Extended Data Fig. 4: Petrology and chemical composition of quartz-bearing clasts.
From: Evidence for pre-Noachian granitic rocks on Mars from quartz in meteorite NWA 7533
SEM BSE images and corresponding SEM EDS mapping of four quartz-bearing clasts (QBC) identified in the quartz-bearing CLMR of NWA 7533. The lithic clasts shown are (a) clastno. 1, (b) clast no. 3, (c) clast no. 4, and (d) clast no. 5. Qtz = quartz, Kfs = K-feldspar, Pl = plagioclase, Px = pyroxene, Il = ilmenite, Ap = apatite.
