Extended Data Fig. 2: Petrology of the quartz-bearing CLMR.
From: Evidence for pre-Noachian granitic rocks on Mars from quartz in meteorite NWA 7533
(a) SEM BSE map of the quartz-bearing CLMR where all the quartz grains, including those contained in quartz-bearing clasts, were found in section SP10. (B) The close-up BSE map illustrates the varied and complex microtextures observed in this melt zone, including pyroxene clumps with a plagioclase aureole as described in Hewins et al.8. A fine-grained rim surrounds the inner vitrophyric melt (b).
