内蒙古呼山煤盆地乌固诺尔勘查区地质特征及其聚煤规律研究

Analysis on Geological Characteristics and Coal Accumulating Pattern in Wagner Area of Hushan Coal Basin in Inner Mongolia

摘要:

乌固诺尔勘查区是一个大型的陆相沉积煤盆地，主要含煤地层为早白垩世伊敏组和大磨拐河组，煤炭资源丰富，为呼山煤盆地中的富煤盆地之一。通过对勘查区已有地质资料，并结合其结构、构造、岩性、厚度以及岩相特征等资料进行分析研究，初步了解了勘查区的形成、演化及聚煤规律。

Abstract:

Wagner area is a giant continental sedimentary coal basin with abundant coal reserve. Main coal layers are Yimin group and Damo Guaihe group in lower series of Cretaceous system. They are one of the coalrich basins in Hushan coal basin. Based on previous geological information, combining with analysis and study on structures, texture, lithology, thickness and lithofacies characterisitcs, emergence, evolution and coal accumulating pattern of this basin have been studied.
