noctis labyrinthus drainage pattern

Noctis Labyrinthus is notable for its unusual pattern of intersecting valleys, which give the region a maze-like appearance when viewed from above. This image from NASA's Mars Reconnaissance Orbiter shows a small (0.4 kilometer) mesa, one of several surrounded by sand dunes in Noctis Labyrinthyus, an extensively fractured region on the western end of Valles Marineris. The order of this layering is unique to the unnamed depression and is typically reversed in most Martian contexts, with the mafic smectites forming the bottom Noachian-age layer. Include a simple sketch of the drainage below. Question: WATER INTRODUCTORY GEOLOGY Now Let's Travel To Mars! The deflection pattern implies at least 11 km of left-slip motion after the initiation of the deflected drainage system . These features you are seeing are linear valleys. This hypothesis has been challenged because carbonate spectral signatures have not been detected in the Noctis Labyrinthus network. The rock layers in this image were likely horizontal when the materials were first deposited, but are now tilted to high angles, approaching 90 degrees, so we get a … 3D). Dust covers most of this region, leading to its rather uniform appearance. In this Viking 1 image, the canyons of Noctis Labyrinthus are filled with water ice fog from frost sublimated by the early morning sun. Identify any evidence of erosion/deposition in the valley floor and suggest a process by which this valley may have formed.Locate Noctis Labyrinthus (this feature is on the western edge of Vallis Marineris, the “Grand Canyon of Mars”).Assume that water has flowed through this area: what type of drainage pattern is … Thin dark layers on floor of Noctis Labyrinthus; enlargement from same image. Courtesy NASA/Malin Space Science Systems. Noctis Labyrinthus is an intricate system of Late Hesperian and Early Amazonian linear troughs and rounded pits con- necting the Tharsis volcanic rise and western Valles Marin-eris next to Martian equator. Figure 13.8 Left: a typical deranged pattern; right: a typical radial drainage pattern developed around a mountain or hill. [6] Based on CRISM spectral imagery, authors studying this depression have interpretatively identified the presence of: Of the hydrated iron sulfate minerals observed in the basin, some of them - such as ferricopiapite - are not stable in modern Martian conditions. These features you are seeing are linear valleys. The polygonally fractured western Noctis Labyrinthus marks the present summit region (middle); ancient radially fractured plains, some of Noachian age , extend to the north, where lava flows and small shields from the younger Tharsis Montes region embay and are superposed on the ancient fractured deposits. [24] Noctis Labyrinthus [left]. In some places, particularly notable in the lower-right corner of the plan view image (above), wind has drawn the dust into dune fields that extend up onto the surrounding plateaus. This hypothesis is not widely favored because chaos terrain morphology, proposed to form from this mechanism, is not found in the Noctis Labyrinthus fracture network.

Suggest some possible place/feature names - you might also wish to explore the Colorized Terrain … Noctis Labyrinthus is a group of intersecting canyons that lies at the western end of Valles Marineris. These deposits, dated to the late Hesperian, post-date most Martian deposits of hydrated minerals. Let's Look At A Few Fea- Tures On Mars. Grabens happen when a center section drops lower than sections on either side. The transition zone between maze-like troughs of Noctis Labyrinthus and the main Valles Marineris canyon system are shown in this THEMIS visible camera image. Locate Noctis Labyrinthus Assume that water has flowed through this area: what type of drainage pattern is present here? ... drainage patterns. [8] Some authors have also proposed that Noctis Labyrinthus' chasmata may have formed due to extensional faulting in weakened rocks composed of interlayered tuff and lava flows, known to produce pit crater chains parallel to graben. The pit is the only one of its kind in Noctis Labyrinthus and has a greater variability than almost any other location yet observed on the planet. Assume that water flowed through these valleys at some time. [5] Because of its location at the center of the Tharsis uplift, the melting associated with this creep could have been facilitated by increased heat flow to this area during periods of increased magmatic activity. 9. One hinged slab (Big Slab) on the north wall is not incised (Fig. plagioclase) diminishing the acidity and thus kinds of minerals observed. 7. Assume that water has flowed through this area: what type of drainage pattern is present here? [2] It is thought that this faulting was triggered by volcanic activity in the Tharsis region. Geomorphologists and hydrologists often view streams as being part of drainage basins. The region is notable for its maze-like system of deep, steep-walled valleys. Layers in the lower portion of two neighboring buttes within the Noctis Labyrinthus formation on Mars are visible in this image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

A fourth type of drainage pattern, which is not specific to a drainage basin, is known as radial (Figure 13.8, right). a. Trellis b. Dendritic c. Rectangular d. Radial e. Deranged 41. This is a radial drainage pattern (if it was carved by water). In some places the valley floors are rougher, disturbed by landslides, and there are places where the land appears to have sunk down into pit-like formations. 13.2 Drainage Basins A stream is a body of flowing surface water of any size, ranging from a tiny trickle to a mighty river. b. Locate Noctis Labyrinthus (this feature is on the western edge of Vallis Marineris, the “Grand Canyon of Mars”). What does this type of drainage pattern suggest about the underlying bedrock? Landslides are seen in extraordinary detail in the flanks of this unit and along the valley walls (most notable in the perspective view, top), with eroded debris lying at the base of the steep walls. Layers in the lower portion of two neighbouring buttes within Noctis Labyrinthus. 40. These features you are seeing are linear valleys. [6], In 1980, Philippe Masson of the University of Paris-Sud offered an integrated interpretation of the structural geochronology of Valles Marineris, Noctis Labyrinthus, and Claritas Fossae in light of imagery from Mariner 9 and the Viking Orbiter.

The Coprates and Phoenicis Lacus quadrangles of Mars contain the Valles Marineris, Noctis Labyrinthus, and Claritas Fossae areas, each of which shows distinctive structural patterns. The Coprates and Phoenicis Lacus quadrangles of Mars contain the Valles Marineris, Noctis Labyrinthus, and Claritas Fossae areas, each of which shows distinctive structural patterns. An unnamed depression near the southernmost extent of the Noctis Labyrinthus system, near the divide of Syria Planum and Sinai Planum and at the western end of the Valles Marineris, was found to be one of the most mineralogically diverse sites yet observed on the planet. c. The linear channels suggest the material making up the flanks of this volcano is somewhat easily eroded: the most common explanation for this is that the flanks of Apollinaris are covered with pyroclastic material rather than rocky lava flows. Locate Noctis Labyrinthus (this feature is on the western edge of Vallis Marineris, the “Grand Canyon of Mars”). Noctis Labyrinthus, on the eastern edge of the Tharsis Plateau, ... , and display first and second order parallel drainage patterns. (Answer options include Radial, Dendritic, Rectangular, or Trellis) Other articles where Dendritic drainage pattern is discussed: valley: Drainage patterns: Dendritic patterns (see figure), so called because of their similarity to branching organic forms, are most common where rocks or sediments are flat-lying and preferential zones of structural weakness are minimal. What does this type of drainage pattern suggest about the underlying bedrock? [7] In the chasmata of Noctis Labyrinthus, these pit crater chain collapse zones propagate directionally with a V-shaped tip, and can be used as an indicator of the direction into which magma withdraws from its underlying chamber. The region is notable for its maze-like system of deep, steep-walled valleys. [6], Moasic of Viking 1 Orbiter pictures showing location of Noctus Labyrinthus. As the underlying magma body drains, the chamber's pressure decreases and it begins to deflate. Chasmata and pit crater chains like those of Noctis Labyrinthus are likewise also not observed near areas where phreatomagmatic activity is strongly believed to have occurred, such as the Sisyphi Montes. It is in the Phoenicis Laus quadrangle. Close-up of complex, dark dunes in the previous image of the floor of Noctis Labyrinthus, as seen by HiRISE under HiWish program. Light-toned butte on floor of Noctis Labyrinthus; enlargement from same image. Scientists have wondered if Mars ever had rainfall. [8], Other authors have suggested that phreatomagmatic processes were associated with the formation of the Noctis Labyrinthus chasmata. Noctis Labyrinthus is notable for its unusual pattern of intersecting valleys, which give the region a maze-like appearance when viewed from above. The latter material is interpreted as such from an unusual doublet shape resolved on its spectra. Include a simple sketch of the drainage; take a digital photograph of your sketch to include in your lab report. Locate Noctis Labyrinthus Assume that water has flowed through this area: what type of drainage pattern is present here? [8] Critics of a purely tectonic hypothesis have also noted that although pit crater chains (central to the diking hypothesis) are generally aligned and coincident with graben, they are occasionally found to bifurcate and to cross coeval graben in a perpendicular direction in the vicinity of Noctis Labyrinthus. This is a radial drainage pattern (if it was carved by water). The chronological relationships among these trends and their relation to the stratigraphy has been determined. Include a simple sketch of the drainage; take a digital photograph of your sketch to include in your lab report. a. Trellis b. Dendritic c. Rectangular d. Radial e. Deranged 41. The walls of these valleys are very high (~5 km) and quite steep, with slopes approaching 35degs. Floor of Noctis Labyrinthus showing layered structures, as seen by HiRISE under HiWish program. Radial patterns form around isolated mountains (such as volcanoes) or hills, and the individual streams typically have dendritic drainage patterns. b. Many canyons have a classic graben form, with the upland plain surface preserved on the valley floor. [5], The Noctis Labyrinthus fracture zone is centered at the heart of the Tharsis Rise, dividing a plateau of Hesperian-Noachian age that is understood to be of a basaltic composition.

Include a simple sketch of the drainage; take a digital photograph of your sketch to include in … It has a diameter of 1190.31 km. The entire network of plateaus and fractures spans some 1200 km, about the equivalent length of the river Rhine from the Alps to the North Sea. Using CRISM spectral data on HiRISE visual images for context, the researchers proposed that the variability of this pit is a result of hydrothermal alteration, with the dissolution of extant calcium-rich minerals (e.g. Identify any evidence of erosion/deposition in the valley floor and suggest a process by which this valley may have formed.Locate Noctis Labyrinthus (this feature is on the western edge of Vallis Marineris, the “Grand Canyon of Mars”).Assume that water has flowed through this area: what type of drainage pattern is present here?

Other articles where Trellis drainage pattern is discussed: river: Drainage patterns: Trellis (or espalier) drainage patterns result from adjustment to tight regional folding in which the folds plunge. A pattern of drainage which is branching, ramifying or dichotomising, thereby giving the appearance of a tree. [3] Research described in December 2009 found a variety of minerals, including clays, sulfates, and hydrated silicas, in some of the layers. 40. [6] No evidence of fluvial or aeolian erosion is observed in this region.[5]. Denudation produces a zigzag pattern of outcrops, and adjustment to this pattern produces a stream net in which the trunks are aligned on weak rocks exposed along fold… Apollinaris Mons is an ancient shield volcano in the southern hemisphere of Mars.It is situated near the equator, south of Elysium Planitia and north of the impact crater Gusev (the landing site of the Mars rover Spirit).Elysium Planitia separates it from the volcanic province of Elysium to its northwest. A chain of crater-like depressions forms, where the extent of the collapse dictated by how deeply the magma body is located. [4], Noctis Labyrinthus is located in the heart of Tharsis at the western end of the Valles Marineris, manifesting as a network of graben that extends in a spider-like network before coalescing into a coherent, relatively shallow graben swarm that curves in a semicircular fashion towards the south into the Claritas Rise. The origin of the canyon by faulting is most apparent in Noctis Labyrinthus at the western end of Valles Marineris. Assume that water has flowed through this area: what type of drainage pattern is present here? [6] Some researchers have counterproposed that rather than a sequentially reversed depositional event, this basin formed in a single, highly heterogeneous event. The three large mountains on the left are Tharsis Montes. Denudation produces a zigzag pattern of outcrops, and adjustment to this pattern produces a stream net in which the trunks are aligned on weak rocks exposed along fold… The Coprates quadrangle goes from 0° to 30° south latitude and 45° to 90° west longitude (315-270 E). 6. What does this type of drainage pattern suggest about the underlying bedrock? The walls of these valleys are very high (~5 km) and quite steep, with slopes approaching 35degs. Image is 20 mile wide. Analyses of the structural trends seen within these quadrangles show four principal trend directions. The center coordinates of Noctis Labyrinthus are 7.0 S and 102.2 W (257.8 E). 40. The researchers offered the first theoretical explanation as to how the chasmata of Noctis Labyrinthus formed. This block of martian terrain, etched with an intricate pattern of landslides and wind-blown dunes, is a small segment of a vast labyrinth of valleys, fractures and plateaus. The region, known as Noctis Labyrinthus – the “labyrinth of the night” – lies on the western edge of Valles Marineris, the grand canyon of the Solar System. Layers probably contain a variety of minerals that were formed with groundwater. The canyons of this feature are faults known as grabens. Here, we show that Noctis Labyrinthus, a unique system of troughs connecting the Tharsis volcanic rise and western Valles Marineris, retains geologic evidence of conduit development associated with structurally-controlled groundwater flow through salt-rich upper crustal deposits. a. Include a simple sketch of the drainage; take a digital photograph of your sketch to include in your lab report. Locate Noctis Labyrinthus (this feature is on the western edge of Vallis Marineris, the “Grand Canyon of Mars”). Assume that water has flowed through this area: what type of drainage pattern is present here? Close-up of layers on floor of Noctis Labyrinthus; enlargement from the center of the previous picture. The graben are known as the Claritas Fossae beyond this point. A synthesis of deformation patterns within and around the Thaumasia Plateau, Mars, points to a new interpretation for regional deformation and the origin of Valles Marineris and associated outflow channels. Noctis Labyrinthus context. The region, known as Noctis Labyrinthus – the “labyrinth of the night” – lies on the western edge of Valles Marineris, the grand canyon of the Solar … In the top third of the image, on the western side of the northernmost trough, a buildup of relatively bright … Drainage pattern is the pattern formed by the streams, rivers, and lakes in a particular drainage basin.They are governed by the topography of the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Of the studied pits, 31 pits fell within the HiRISE DEM coverage and were found to have a mean depth of 5.9 ± 1.2 m (Figure 5 ). The linear channels suggest the material making up the flanks of this volcano is somewhat easily eroded: the most common explanation for this is that the flanks of Apollinaris are covered with pyroclastic material rather than rocky lava flows. In the Search tab, type in Noctis Labyrinthus and zoom in to get a good view. 40. RequiredIntroduction to the Solar System in Earth science. Open Educational Resource.Inner Planets in Earth science. Consider the material that makes up Apollinaris: what does the presence of these linear channels suggest about the strength (ability to resist erosion) of the underlying material? 9. a. Include a simple sketch of the drainage below; take a digital photograph of your sketch to include in your lab report. Noctis Labyrinthus (Latin: the labyrinth of night) is a region of Mars between Valles Marineris and the Tharsis upland. [7], Other authors have proposed an alternate origin for Noctis Labyrinthus, linking its formation to the Valles Marineris and likening its initial formation to the expansion and collapse of a dense lava tube network. Noctis Labyrinthus (Latin: labyrinth of the night) is a region of Mars between Valles Marineris and the Tharsis upland. The formation of the fracture zone have been dated to the Late Hesperian based on crater countingage date… The straight alignments of many canyon walls, and the faulting in several directions associated with Noctis Labyrinthus, combine to suggest that the Valles Marineris system is composed of great rift valleys formed on the surface of a dome. Such drainage could occur slowly, fulfilling the requirement that interdune deposition be low energy, and only partial burial could be accounted for by the many different paths such drainage could take.

Locate Noctis Labyrinthus (this feature is on the western edge of Vallis Marineris, the “Grand Canyon of Mars”). Coprates quadrangle is famous for depicting the "Grand Canyon of Mars", the Valles Marineris Canyon System. Locate Noctis Labyrinthus (this feature is on the western edge of Vallis Marineris, the “Grand Canyon of Mars”). The total left-slip motion of the southern Valles Marineris fault zone is estimated to be 150–160 km, which may have been absorbed by east-west extension across Noctis Labyrinthus and Syria Planum in the west and across Capri and Eos Chasmata in the east. [6] Furthermore, opaline silica deposits observed within this depression display spectra that may occasionally suggest interpersal with the iron sulfate mineral jarosite and the phyllosilicate mineral montmorillonite.
