PhD-project: Developing Strategies For Predicting Locations Of Past Hydrothermal Activity On Mars

It is increasingly recognized that hydrothermal activity has occurred on Mars. Geomorphological and mineralogical evidence show that Mars hosted at some point and for some time a hydrosphere. Massive volcanic provinces and giant rift systems occur which could have harbored hydrothermal systems. Moreover Mars’ surface is saturated with impact craters, varying from a few meters to thousands of kilometers in diameter. Impacts therefore provided another heat source, possibly resulting in impact-induced hydrothermal activity (IIHA) and associated mineralization. ‘Signals’ of hydrothermal activity in impact craters could include the occurrence of crater mounds, crater deltas, possible crater lake deposits, CRISM derived clay signatures inside craters and valley networks around crater rims.
The spatial pattern is investigated to determine if the signals are random, i.e. controlled locally by the impacts themselves, or non-random and controlled by the surrounding pre-impact structure and geology.
