(1) The principal rock-forming minerals and rock-grains found in Koyama and Shimohojo sand-dune soils in Tottori district, are quartz, microcline, orthoclase, oligoclase, augite, hornblede, hypersthene, biotite, magnetite, ilmenite, zircon, apatite, ferruginous quartz, quartzite, siliceous slate and chert. (2) From the observation on the relative stability. to weathering of rock-foming minerals and rock-grains found in surface layers (0〜10 cm in depth) and underlaying layers (90〜100 cm in depth) of Koyama and Shimohojo sand-dune soils, a weathering sequence (ordered in stability in every category) of these minerals and rock-grains was presumed as follows : Most stable : quartz, zircon. Stable : magnetite, ilmenite, apatite. Moderatly stable : hornblende, augite hypersthene, quartzite, chert, ferruginous quartz, siliceous slate. Least stable : microcline, orthoclase, oligoclase, biotite.
