Raman spectroscopy of sediments from the Antarctic Dry Valleys; an analogue study for exploration of potential paleolakes on Mars
Abstract A Raman spectroscopic study was performed on igneous sediments dominated by plagioclase, K‐feldspar, quartz and pyroxene from the Dry Valleys region of Antarctica. Lakes from this region of Antarctica have been investigated as possible analogues for paleolake environments on early Mars. Gai...
