摘要：

A clay mineral investigation of certain subalpine soils showed the presence of smectitic clay in the upper sola. A more detailed study suggested that these clays wee forming authigenically and further, that they were formed through synthesis of amorphous material, probably from a volcanic ash source, accompanied by some degradation of primary chlorite and illite.
