此篇分中国东部地壳运动为四大期,(一)秦领期在古生代之末在东部不甚显著·(二)燕山期在东部范围较广南北皆有,其时代在侏罗纪终,白垩纪前,其连带现象为花岗闪长岩之侵入及接触铁矿及铜矿之生成,造山运动终後则有斑状火山岩流之喷出.(三)南领期南方花岗岩及金属矿带之生成约在第三纪初或至早白垩纪终.(四)陇山期第三纪後半期之摺曲惟甘东及川东较著。
This paper points out that the crustal movement in eastern China has four major phases, (1) the Qinling period was not significant in the eastern part of the Paleozoic, and (2) the Yanshanian period had a wider area in the east than in the north and south. At the end of the Jurassic period, Before the Cretaceous, its associated phenomena were the intrusion of granodiorite and the formation of iron ore and copper ore, and the eruption of porphyritic volcanic rocks after the orogenic movement. (3) The southern granite and metallogenic belt Was formed around the beginning of the Tertiary or early Cretaceous. (4) The bending of the late Gansu and Gansu eastern parts of the Longshan period was evident.
