Evaporative Salts from Saline Lakes on Tibet Plateau: an Analog for Salts on Mars,

Martian salts: Salts have been identified on Mars by spectrometers on orbiters and rovers. Among them, Mg-, Ca-, and Fesulfates were identified or implied in Meridiani outcrop [1] and in Gusev salty soils and rocks [2,3]; kieserite (MgSO4.H2O) and “polyhydrated sulfates” were found in Valley Marineris, Meridiani Planum, and gypsum (CaSO4.2H2O) near North Pole [4,5,6,7]. Recently, chloride-beari...

Experimental studies of Mars-analog brines

Evaporite deposits may represent significant sinks of mobile cations (e.g., those of Ca, N, Mg, and Fe) and anions (e.g., those of C, N, S, and Cl) among the materials composing the Martian surface and upper crust. Carbon and nitrogen are especially interesting because of their role as atmospheric gases which can become incorporated into crustal rocks. However, the nature of evaporite precursor...

Endolithic cyanobacteria in halite rocks from the hyperarid core of the Atacama Desert.

In the driest parts of the Atacama Desert there are no visible life forms on soil or rock surfaces. The soil in this region contains only minute traces of bacteria distributed in patches, and conditions are too dry for cyanobacteria that live under translucent stones. Here we show that halite evaporite rocks from the driest part of the Atacama Desert are colonized by cyanobacteria. This coloniz...

Model Crystals to Test Techniques in Astrobiological Exploration of Evaporites on Mars

Introduction: The search for life on Mars involves many potential strategies for the analysis in situ of surface samples or the analysis of returned samples in a controlled environment, in particular analyses seek evidence of tangible life and/or biomolecules. It is important to develop mineralogical standards suitable for testing the techniques that will be used for these analyses. Evaporites ...

Acid-sulfate Weathering of Synthetic Martian Basalt: the Acid Fog Model Revisited

Introduction: One of several models that has been proposed to explain the present chemical and minera-logical nature of the Martian surface is referred to as the " acid-fog " model. This model involves the recent (up to 1Ga), slow and continuous interaction of acidic volatiles, presumably of volcanic origin, with the exposed Martian basaltic crust [1, 2]. As a result of this interaction, minera...
