Home Plate is a plateau in the Columbia Hills of Gusev Crater [1]. It is a layered sequence of clastic rocks with alkali basaltic composition. Based on stratigraphy, structure, sedimentology, mineralogy, and bulk chemistry it is interpreted as pyroclastic deposit and thought to be extensively hydrothermally altered [1-5]. The hydrothermal alteration is presumed to be of high and low temperature...

The tufts at Yucca Mountain in south-central Nevada are being studied by the Yucca Mountain Project (YMP) to determine their suitability for a high-level radioactive waste repository. For predictive purposes, it Is important to understand the alteration history of Yucca Mountain and to know how the minerals in Yucca Mountain tufts respond to changing conditions such as elevated temperatures. Th...

Abstract Constraining deep-water recycling along subduction zones is a first-order problem to understand how Earth has maintained hydrosphere over billions of years that created conditions for habitable planet. The pressure-temperature stability hydrous phases in conjunction with slab geotherms determines much H2O leaves the or transported deep mantle. Chlorite-rich, metasomatic rocks form at s...
