Extended Data Fig. 3: Chemical composition of CLMR in NWA 7533.
From: Evidence for pre-Noachian granitic rocks on Mars from quartz in meteorite NWA 7533
Chemical composition of the quartz-bearing CLMR (in yellow) and of other CLMR (in pink, see Extended Data Fig. 2 for location of each CLMR from corresponding numbers) compared to the bulk matrix of NWA 75337. (a) CaO versus MgO, (b) Al2O3 versus FeO. Average compositions are derived from the average of electron microprobe data obtained on a series of ten to twenty 12*9 μm raster point analyses. Error bars are standard deviations for these analyses (see Supplementary Table 1).
