北京石灰岩成矿规律研究

Study on Metallogenic Regularity of Limestone in Beijing

石灰岩为北京地区优势特色矿产,资源量丰富,集中分布在北京西山和北山地区,赋矿地层主要为寒武系与奥陶系。本文收集了北京地区石灰岩矿产地分布信息,对其赋矿地层、规模以及构造特征进行研究,探讨了北京地区石灰岩矿产地质特征及其分布规律,提出北京地区石灰岩成矿区带划分方案,总结了各区带成矿地质特征,研究成果进一步提升北京石灰岩矿产地质认识,为地方矿政管理提供了重要参考。

This paper discusses the geological characteristics and distribution rules of limestone mineral resources in Beijing.Limestone is the dominant characteristic mineral resources in Beijing.The deposits are mainly distributed in the Xishan and Beishan areas with abundant resources.The cambrian and ordovician are the main ore bearing strata.According to the distribution of ore deposits,stratigraphic and structural characteristics,we divide the limestone metallogenic belts and summarize the metallogenic geological characteristics.This paper enhances the understanding of limestone mineral geology in Beijing and provide an important reference for the local mining administration。
