摘要
通过野外剖面踏勘情况、采集样品实验结果的综合分析,系统研究了新景矿含煤岩系沉积环境及其聚煤特征。运用岩石学、有机化学、测井相分析等研究手段,识别出新景矿山西组沉积环境为河控浅水三角洲沉积,并进一步将其三角洲沉积相划分为3个亚相和8个微相,对其主要特征逐一进行了描述。
In order to clarify the spreading regularity of every coal seams in Xinjing and give a hand to coal producing, it is necessary to understand the sedimentary environment of coal-bearing strata and the law of coal-gathering. Based on study and analysis of core data, well logging data and outdoor section reconnaissance in Xinjing, the writer identified that Shanxi formation in this area is a kind of shallow-water delta depositional environment controlled by river, and further divided it into 3 subfacies and 8 microfacies, by using principles and methods of petrology, geochemistry, geophysics, at the same time, described its main features individually.
