TL;DR: Higher abundances of chlorinated hydrocarbons in the mudstone compared with Rocknest windblown materials previously analyzed by Curiosity suggest that indigenous martian or meteoritic organic carbon sources may be preserved in the Mudstone; however, the carbon source for the chlorinatedHydrocarbons is not definitively of martian origin.

TL;DR: In this article, high-speed slip experiments performed on Westerly granite using friction welding apparatus reveal that comminution is an essential precursor to melting by friction, which is not mutually exclusive process.

TL;DR: In this paper, it was observed that phyllosilicates and amphiboles are preferentially consumed to form the melt phase, whilst quartz and feldspar tend to survive as clasts.

TL;DR: The 1990 Geological Society of America Annual Meeting in Dallas, Texas, U.S.A as mentioned in this paper brought together researchers working on various aspects of frictional melting in rock, to provide a forum for the exchange of new ideas and to encourage the production of a thematic set of papers dedicated to the topic.

TL;DR: In this article, the available age data from Greek and Yugoslavian ophiolites and related rocks are reviewed and, where necessary, have been corrected using the decay constants of Steiger & Jäger (1977).
