Abstract
This is a critical review of “On Major Tectonic Forms of China” by Dr. Huang. Her history of tectonic development is classified by him into the Caledonian, Variscan, Indochinese, Yenshan and Himalayan cycles. Kobayashi is of opinion that the late Variscan movements are appropriate for Eastern Asia to combine with the Indochinese ones into the Akiyoshi cycle. He notes further that the so-called Yenshan orogenic cycle is the late Mesozoic synorogeneses in the Koreo-Chinese Heterogen which was caused by the Sakawa orogenic cycle of the pen-continental geosyncline. While this cycle constructed the folded mountains of the Alpine type (s. 1.), the synorogenic disturbances destructed the heterogen. The so-called Yenshan granite is a product of the batholithic invasion of the Chugoku granite (s. 1.) into the hinterland of the pen-continental Sakawa folded mountains.
