摘 要: 结合区域构造特征及矿区构造演化,分析了益新矿区含煤岩系的地层、岩性、岩相和沉积旋回特征,对益新矿区石头河子组和石头庙子组的沉积演化进行了研究。研究表明:益新矿区晚侏罗世含煤岩系的沉积环境主要为石头河子组滨湖—湖泊—湖泊三角洲沉积体系。湖泊三角洲和湖泊於浅沼泽化,大量植物茂盛生长、死亡、堆积形成较厚煤层。
关 键 词: 地质学;益新煤矿;石头河子组;沉积演化

Abstract: The paper combines the regional tectonic characteristics and mining area structure evolution, analyzes the characteristics of formation, lithology, lithofacies and sedimentary cycle of coal-bearing rock system in Yixin mine, and then researches the sedimentary evolution of Shitouhezi group and Shitoumiaozi group in Yixin mine. The results show that the main sedimentary environment of coal-bearing rock system of Yixin mine in late Jurassic was the lakeshore-lake-lake delta sedimentary system during the Shitouhezi deposition period. The main coal accumulation was due to swamping of the lake delta and disappearance of lakes. Then, a large number of plants flourished, died, accumulated, and formed thick coal seams.
Key words: geology; Yixin mine; Shitouhezi group; sedimentary evolution
