黔桂地区早泥盆世晚期碳稳定同位素变化及其对海平面变化的响应
The carbon isotope variation and its responses to sea level changes during the late Early Devonian period in Guizhou and Guangxi
摘要
Abstract
Based on the sedimentary sequence characteristics of the typical sections in different facies zones in Guizhou and Guangxi, the authors recognized two obvious sea level fluctuations during the late Early Devonian period. On such a basis, the sedimentary sequences are divided into two third grade sequences(SQ1, SQ2). The sequences (SQ1, SQ2)can be correlated regionally. In addition, the authors observed that the curve ofδ13C from Lower Devonian Dale Formation in Xiangzhou of Guangxi is coincident with the curve of the regional sea level fluctuations. This study indicates that the geochemistry as well as the sequences was well controlled by the sea level changes.关键词
