Size distribution
2 different distributions for quartz (~200 µm) and ferruginous clay (micron-sized). Quartz grains mostly below 300 µm, but a few brown agglomeration of grains with 500-1500 µm
Size method
sieving with mesh of 160 µm
Oxides comments
oxide composition of the raw powder is given in parent matter. Should be different in this size fraction

  Name Arrangement Mass (g) Mass fraction Abundance comments
Quartz grains grains coated by ferruginous clays relative abundance not yet determined, but larger than 60 vol% of the raw powder
brown kaolinite clay with goethite ferruginous clays coating or cementing quartz grains relative abundance not determined, but much smaller than 40 vol% of the raw powder
