华南煤炭资源分布与赋煤构造分区

Coal Resources Distribution and Tectonic Division in Southern China

华南赋煤区是我国重要的二叠纪煤炭资源分布区,煤田构造复杂,资源分布极不平衡,对该区开展煤炭资源与赋存特征研究尤为重要。从煤炭资源时空分布特征入手,以赋煤构造分区与控煤研究为主要研究内容,将华南赋煤区划分为扬子和东南2个赋煤构造亚区,18个赋煤构造带(点),着重分析了扬子陆块北缘逆冲赋煤带、滇东褶皱赋煤带、赣中湘南粤北坳陷赋煤带和上饶—安福—曲仁坳陷赋煤带4个赋煤构造带的控煤特征,有助于对该区煤炭资源评价和勘查。

Southern China is the important Permian coal resource distribution area. It has complex coalfield structure and extremely unbal- ance resource distribution, which is significant to study the coal resource and occurrence characteristis of this district. This paper is mainly about researching the coalfield tectonic distribution and coal controlling characteristics based on the spatial and temporal distribution of coal resources.Divided into Yangtse coal occurrence tectonic sub-district, southeast coal occurrence tectonic sub-district and eighteen coal occurrence tectonic zones（point） of this district. Focus on analyzing the four coal occurrence tectonic zones ,which are north edge of Yan- gtse landmass thrust coal occurrence zone, Diandong fold coal occurrence zone, Ganzhong-Xiangnan-Yuebei depression coal occurrence zone and Shangrao-Anfu-Quren depression coal occurrence zone. It contributes to overall understanding of coalfield tectonic framework.
