Catalog Page for PIA02065 Ganges Chasma is part of the Valles Marineris trough system that stretches nearly 5,000 kilometers (3,000 miles) across the western equatorial region of Mars. The smooth floor of Ganges Chasma, particularly in the area south and west of the bright stack of layered material, is a thick, relatively flat sheet of dark, windblown sand. Ganges Chasma is approximately 3 to 5 kilometers (2-3 miles) deep. photojournal.jpl.nasa.gov /catalog/PIA02065   (392 words)

Last check: 2007-11-05) Ganges Chasma is part of the Valles Marineris canyon system that stretches nearly 5,000 kilometers (3,000 miles) across the western equatorial region of Mars. The floor of Ganges Chasma is a thick, relatively flat sheet of dark windblown sand. The jumbled troughs and depressions that run from the north side of Ganges Chasma toward the upper right corner of the image were caused by a cavern forming under the surface followed by a partial collapse. starryskies.com /solar_system/mars/3d-gallery/39.html   (300 words)

Mars Odyssey Mission THEMIS: Feature Image: Rockslides and Outcrops in Ganges Chasma This portion of Ganges Chasma, part of the Valles Marineris canyon system, contains several enormous overlapping landslides and provides scientists a view into the misty depths of martian geologic time. Ganges Chasma slices through almost 5 km (3 miles) of the martian crust and reveals ancient rocks and layers in the walls of the canyons that would otherwise be unseen. The presence of this mineral indicates that this region has remained relatively dry, because olivine weathers away rapidly in watery environments. themis.asu.edu /feature_ganges   (252 words)

Mars Global Surveyor MOC2-295 Release   (Site not responding. Last check: 2007-11-05) Ganges Chasma---or Gangis Chasma (as it is sometimes spelled)---is a several kilometers-deep side canyon at the east end of the vast Valles Marineris trough system. In several places, portions of the steep walls of Ganges Chasma have collapsed down into the chasm, creating large landslide deposits. The linear grooved and ridged pattern of the upper surface of the landslide results from shear as the mass of rock and debris was moving across the landscape. mars.jpl.nasa.gov /mgs/msss/camera/images/10_30_01_releases/ganges/index.html   (233 words)

Mars Odyssey: Multimedia The color differences in this image show compositional variations in the rocks exposed in the wall and floor of Ganges (blue and purple) and in the dust and sand on the rim of the canyon (red and orange). The floor of Ganges is covered by rocks and sand composed of basaltic lava that are shown in blue. A layer that is rich in the mineral olivine can be seen as a band of purple in the walls on both sides of the canyon, and is exposed as an eroded layer surrounding a knob on the floor. mars.jpl.nasa.gov /odyssey/gallery/canyons/PIA04262.html   (261 words)

Ganges Sedimentary Rocks :: Mars Astrobiology Magazine :: Search for Life on Mars Mariner 9 images acquired in 1972 first revealed a large, light-toned, layered mound in Ganges Chasma, part of the vast Valles Marineris trough system. These rocks record a history of events that occurred either in Ganges Chasma, or in the rocks brought to the surface by the opening of Ganges Chasma.

Mars Odyssey Themis Image - Ganges Chasma Sand Sheet A sand sea differs from a dune field in two ways: 1) a sand sea has a large regional extent, and 2) the individual dunes are large in size and complex in form. Today's sand sheet is located in the Ganges Chasma portion of Valles Marineris. As with yesterday's image, note that the dune forms are seen only at the margin and that the interior of the sand sheet at this resolution appears to completely lack dune forms. www.blackanthem.com /scitech/2005041604.html   (300 words)

PSRD: Olivine on Mars Spectroscopists determine that the composition of the Ganges Chasma floor is basaltic and that the walls contain a discrete layer of basaltic rock with 10 to 15% olivine of composition Fo This layer of olivine is being examined with Mars Odyssey THEMIS data (see image below). E), orange and red tones on the plateaus are dust, blue on the canyon floor is basalt, and the purple bands trending east-west in the canyon walls are olivine-bearing basalt. Their work shows that olivine-bearing rocks in Nili Fossae, Ganges Chasma, and other areas resemble the mineralogies of meteorites ALH A77005 (~55% olivine) and Chassigny (~90% olivine) with ~Fo composition. www.psrd.hawaii.edu /Nov03/olivine.html   (2063 words)

SPACE.com -- New Mars Photos Show Lively Landscape Toe of Ganges Chasma Landslide: The grooved and ridged pattern of the upper surface results from shear. Some Mars scientists have speculated that removal of ground ice could cause the pitting, but whether this is actually the case is unknown and cannot be known with any certainty from the photograph alone. More upheaval is visible at several spots in the Ganges Chasma, a canyon at the East end of the vast Valles Marineris trough system, where steep walls, several kilometers high, have collapsed into the chasm, leaving enormous landslide deposits. www.space.com /scienceastronomy/solarsystem/mgs_oct_pics_011107.html   (984 words)

Eos Chasma - Wikipedia, the free encyclopedia Eos Chasma is a chasma in the southern part of the Valles Marineris canyon system of Mars.

AGU Journal highlights - 14 April 2005 The 1976 Viking Orbiter was the first spacecraft to collect images of landslides in the Ganges Chasma, a large canyon on Mars. Recalculating the dimensions using the newer data, they conclude that the Martian landslide may be the result of a slow gravity-driven process over the course of millions of years, not the catastrophic event previously suggested. The researchers propose that rock terraces can be explained by deep-seated gravitational creep, while the movement of the talus is similar to that of slow-moving rock glaciers on Earth, but they concede that this would require ice, which has not yet been found in Ganges Chasma. www.eurekalert.org /pub_releases/2005-04/agu-ajh041405.php   (2196 words)

STRATIGRAPHIC ANALYSIS OF GANGES MENSA, MARS   (Site not responding. Last check: 2007-11-05) Many theories have been proposed for their origin, the most likely being volcanism (subaqueous or subglacial) and lacustrine deposition. Ganges Mensa, located at -7.5 N, -49.0 W in the middle of Ganges Chasma in eastern Valles Marineris, Mars, is approximately 100 km long, 50 km wide, and, in parts, stands 4 km high. Co-registering the Viking Mars Digital Image Map, 13 Mars Orbiter Camera swaths, and Mars Orbiter Laser Altimeter data allowed examination of the deposits' stratigraphy. gsa.confex.com /gsa/2001AM/finalprogram/abstract_29177.htm   (324 words)

JPL.NASA.GOV: News Releases During its first year of surveying the martian surface, Odyssey's camera system provided detailed maps of minerals in rocks and soils. "A wonderful surprise has been the discovery of a layer of olivine-rich rock exposed in the walls of Ganges Chasm. Olivine is easily destroyed by liquid water, so its presence in these ancient rocks suggests that this region of Mars has been very dry for a very long time," said Dr. Philip Christensen, principal investigator for Odyssey's thermal emission imaging system at Arizona State University, Tempe. www.jpl.nasa.gov /news/news.cfm?release=2003-034   (429 words)

An Odyssey Of Mars Science: Part 2 TES first found evidence of olivine in small surface outcrops sprinkled across Mars, and THEMIS' maps have allowed us to locate them far more precisely. There is one 100-meter thick layer of it clearly exposed in the wall of Ganges Canyon -- a side branch of Mars' gigantic Marineris Valley -- which was apparently laid down as an ancient lava flow, and which has been unweathered ever since its exposure to the surface. A larger layer of olivine has been exposed in the Nili Fossae area, on the slopes of the great ancient shield volcano in the Syrtis Major area. www.spacedaily.com /news/lunarplanet-2003-03a2.html   (1562 words)
