descriptive terms (for various sizes) are given in Table A.1 in correlation to rock types;
mineralogical composition
quartz, feldspars and related silicate minerals
dark coloured minerals (e.g. biotite, amphibole, pyroxene)
clay minerals
carbonate minerals (e.g. calcite and dolomite)
siliceous amorphous material (e.g. glass)
carbonaceous material (e.g. coal and graphite)
salts (e.g. halite [rock salt]), gypsum)
swelling minerals (e.g. anhydrite and clay minerals)
sulfide minerals (e.g. pyrite)
void content
primary voids (e.g. gas bubbles in volcanic rocks)
secondary voids (e.g. solution voids)
