Geological Relationships between Hydrated Minerals and Fluvial Landforms in Tyrrhena Terra

چکیده
Introduction: Tyrrhena Terra is located in cratered and dissected Noachian terrains in the southern hemisphere [1] south of Isidia Planitia and north of Hellas basin. Tyrrhena Terra contains both highlands and a series of intercrater plains. In this region, many outcrops of phyllosilicates are observed by OMEGA spectrometer on many craters walls or ejecta [2, 3]. Several plains in Tyrrhena Terra display hydrated minerals. THEMIS Daytime IR images (100m/pixel) and HRSC images (13m/pixel) allow to map fluvial landforms and the different geologic/geomorphic units observed in a part of Thyrrena Terra (76° to 87°E, 6°S to 17°S). These two datasets allow us to study the relationship between the location of hydrated minerals and fluvial landforms.

Introduction: The Phyllosian period of Mars [1] displays rocks that are altered at different levels, containing phyllosilicates of various natures, revealing that liquid water played a strong role in their formation. However, debates currently exist to know if this alteration was conducted at the surface in concert with active hydrologic cycle, or in the subsurface in a hydrothermal or warm, we...
متن کاملPhyllosilicates and Other Hydrated Minerals on Mars: 2. Detailled Analysis
Introduction: Hydrated minerals preserve a record of past aqueous conditions on Mars. Recently, phyllosilicates, hydrated sulphates, hydrated silica have been detected in surface rocks by near-infrared spectrometers on orbiting spacecraft [1-4]. At the kilometer-scale resolution of the OMEGA instrument, phyllosilicate exposures are widespread and number in the dozens [5,6], while early discover...

Introduction: The martian highlands preserve a long and complex history of degradation by fluvial, eolian, and mass wasting processes [1-8]. The effects of these processes are best observed on impact craters that characterize the ancient highlands. Previous studies of highland terrains Margaritifer Sinus [9,10], Ismenius Lacus [11,12], Arabia Terra [13], and Promethei Terra [14,15] have shown t...

Extended abstract 1- Introduction Fluvial and aeolian processes are important factors in changing the surface of morphology in the Earth. When rivers and sand dunes meet, the transportation of sediment between them can lead to one of the systems or both of them change. With their connection between river sediment and wind systems there would be lots of reactions, but very little has been st...
متن کاملThe Role of Water for Martian Habitability
A study in context with the Helmholtz Alliance ‘Planetary Evolution and Life’ focused on the (temporary) existence of liquid water, and the likelihood that Mars has been or even is a habitable planet. Both geomorphological and mineralogical evidence point to the episodic availability of liquid water at the surface of Mars, and physical modeling and small-scale observations suggest that this is ...
