Introduction: The Phoenix Wet Chemistry Laboratory (WCL) has yielded fascinating new information on the nature of soluble minerals present in soils at the northern latitudes of Mars. Put simply, the WCL was designed to soak a soil sample in water and analyze the chemistry of the soil leachate using sensors and electrodes mounted in the walls of the WCL sample cell [1]. Perhaps one of the most i...

The ‘‘mesopore protection hypothesis’’ [Chem. Geol. 114 (1994) 347; Geochim. Cosmochim. Acta 58 (1994) 1271] proposes that organic matter (OM) may be protected from enzymatic degradation by sequestration within mineral mesopores (2–50 nm diameter). This hypothesis is a leading, though controversial, theory in explaining both the preservation of some extremely labile OM compounds and observed co...

Hyperspectral reflectance has the potential to provide rapid and low-cost mineralogical chemical information that can be used vector in mineral systems. However, spectral signature of white mica chlorite, despite numerous studies, is not fully understood. In this study, we review mineralogy chemistry different chlorite types investigate what changes are responsible for apparent shifts shortwave...
