WebSchist has large, flattened grains of platy minerals like muscovite, biotite, and chlorite. These crystals are elongated and oriented roughly parallel to one another. Quartz and feldspar are often present and may or may not be elongated. Larger crystals of bulky minerals like garnet are commonly included. Schist.

WebThe graphitic schist had 0.79 % ROC, which was very similar to the total C of the rock (Tables 1 and 2). Furthermore, the AB soil spiked with graphite, as an additional sample without natural graphite but with a high CaCO 3 content (1.87 % C), showed a similar underestimation as observed with the calibration samples (Fig. 5).
