摘要
This paper,taking lacustrine carbonate rocks of Guanzhuang Group of Pingyi Basin for example,aims at studying the paleogeographic significance of lacustrine carbonate rocks.Taking the sedimentary theory as a guiding theory and based on the outcrop section,the authors analyze the formation and sedimentary features of Guangzhuang Group.The results suggests that the basin was a warm inland environment when lacustrine carbonate rocks were deposited.And the tectonic movement was relatively static,paleotopography was relatively flat,which was favorable to the deposition of the lacustrine carbonate rocks,and carbonate concentration in the environment of shallow water,low and middle energy,little terrigenous fragmental materials.
