中国石炭纪的岩相-古地理和古构造特征

以新的石炭纪地质年表为时间坐标,概述了中国石炭纪各期的岩相—古地理特征及其演变规律:石炭纪为一海浸时期,新村期(C_2~1)和上司期(C_2~2)是其中两个地壳运动比较活跃的阶段,根据古生物地理学、古气候学和古地磁学等方面的资料,揭示了中国和东亚地区石炭纪的古构造格局及其变化历程。

CARBONIFEROUS LITHOFACIES—PALEOGEOGRAPHY AND PALEOTECTONICS IN CHINA

The lithofacies—paleogeography and their evolution during the Carbonifeous in China have been discussed in this paper under the new Carboniferous geologic timescale proposed by the author. Generally speaking,the Carboniferous is a marine transgressive period,among which the Xincunian (C_2~1)and Shaagsian(C_2~3) are two ages of active crustal movements. Based on the paleobiogeographic. paleoclimatic, and paleomagnetic data,the tectonic framework and its evolution during the Carboniferous in China and E. Asia have been discussed in the second part of this paper.
