The geological history of Northeast Syrtis Major, Mars
As inferred from orbital spectroscopic data, Northeast Syrtis Major bears considerable mineral diversity that spans the Noachian-Hesperian boundary despite its small geographic area. In this study we use observations from the High Resolution Imaging Science Experiment, supplemented with Context Camera imagery, to characterize and map the lateral extent of geomorphic units in Northeast Syrtis Ma...
متن کاملThe Syrtis Major volcanic province, Mars: Synthesis from Mars Global Surveyor data
[1] We investigated the geology, stratigraphy, morphology, and topography of Syrtis Major, one of the large Hesperian-aged volcanic provinces on Mars. New data from the Mars Global Surveyor (MGS) and Odyssey spacecraft allowed us to study Syrtis Major in unprecedented detail. On the basis of Mars Orbiter Laser Altimeter (MOLA) data we estimated the thickness of Syrtis Major lavas to be on the o...
متن کاملIdentification of a New Outflow in the Syrtis Major Region, Mars
Introduction: Outflow channels on Mars are formed by very energetic floods suggesting catastrophic episodes of concentrated water flows [1]. These floods comes from a gigantic release of water such as in terrestrial glacial surge, but their exact origin is debated. Outflow channels of the Xanthe Terra region east of the Tharsis area are all of the Late Hesperian epoch and their source regions a...
متن کاملSilica deposits in the Nili Patera caldera on the Syrtis Major volcanic complex on Mars
The martian surface features abundant volcanoes and evidence for past liquid water. Extant or relict martian volcanic hydrothermal systems have therefore been sought in the pursuit of evidence for habitable environments1. The Mars Exploration Rover, Spirit, detected deposits highly enriched in silica with accessory minerals, suggesting formation by hydrothermal leaching of basaltic rocks by low...
متن کاملIdentification of quartzofeldspathic materials on Mars
[1] A unique spectral component has been identified near and on the central peaks of two 30 km diameter craters in northern Syrtis Major. These exposures are clearly visible in Thermal Emission Imaging System (THEMIS) color radiance images as well as THEMIS and Thermal Emission Spectrometer (TES) surface emissivity data. Both TES and THEMIS data indicate the presence of increased 1050–1250 cm 1...
