Extract

The Japanese archipelago, in the temperate zone, has been affected by volcanic and hot spring action in many geological periods including the Recent one. Complicated clay mineral assemblages have been formed by alteration of volcanic glass both by weathering and hydrothermally, and have been studied by the writer and his collaborators (Sudo, 1950b, 1951; Sudo, Minato and Nagasawa, 1951; Sudo and Ossaka, 1952). The present account, based on these studies and on more recent data, deals with acidic to intermediate types of volcanic glass, which are widely distributed in rocks and soils throughout the islands.
