湘西北下寒武统牛蹄塘组石煤研究综述

Reviewing of Research on Stone Coal of Lower Cambrian Niutitang Formation in Northwest of Hunan

石煤是早古生代浅海环境中主要由菌藻类、海绵等原始动、植物遗体在浅海环境条件下经过成千上万年的腐泥化作用和煤化作用而形成的高硫分、高灰分、低热值的劣质煤。中国湘西北下寒武统石煤的蕴藏量大,并且其伴生矿含量也丰富。加强石煤及其伴生矿产的研究,对其综合勘探、综合开发和综合利用等方面意义重大。对湘西北下寒武统牛蹄塘组石煤特征、成因及其伴生的矿产资源进行了综述,最后分析了前人研究中存在的问题,并进一步对研究方向进行了展望。

Stone coal is low-quality coal that is high sulfur content coal, high ash content coal and low heat value coal. It is mainly composed of the original plant and animal, such as bacteria, algae and sponges, remained under the condition of shallow marine environment and got through thousands of years of corrupt argillation and coalification. In China, the northwest of Hunan is abundant in stone coal of Lower Cambrian, which is rich in associated minerals. Therefore, it is very important to do some research of stone coal and its associated minerals, especially in the comprehensive exploration, comprehensive development and comprehensive utilization. This paper summarized the characteristics, causes and associated mineral resources of stone coal of Lower Cambrian Niutitang Formation in the northwest of Hunan, analyzed the problems existing in the previous studies, and further discussed the research direction.
