(SSA) was measured to investigate controls on this parameter for several primary silicate
minerals (PSM) used to estimate rates of weathering. The SSA measured by gas adsorption
for a given particle size of relatively impurity-free, laboratory-ground samples generally
increases in the order: quartz≈ olivine≈ albite< oligoclase≈ bytownite< hornblende≈
diopside. Reproducibility of BET SSA values range from±70%(SSA< 1000 cm2/g) …
