摘　　要：从南华北地区石炭系二叠系有机质热演化的区域地质背景研究入手,根据其有机质热演化程度及其分布规律,对有机质热演化的成因类型进行了研究。指出研究区存在深成(区域)变质和火成接触变质两种类型,且以深成(区域)变质类型为主,火成接触变质类型仅分布在永城等局部地区,对有机质热演化的影响范围极为有限。Starting from the study of geologic background of Carboniferous-Permian organic mass thermal evolution in south Huabei area, a study is conducted on the genesis of thermal evolution of organic mass. It is pointed out that in the studied area there exist katogene metamorphism (area); igneous contact metamorphism, where the katogene metamorphism is dominated, the igneous contacting metamorphism is only distributed in Yongzheng area etc, for which the influence of thermal evolution is greatly limited.
