鹤岗煤田益新矿晚侏罗世含煤岩系沉积演化
首发时间:2009-06-30
摘要:结合区域构造特征,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,进而研究分析了益新矿区石头河子组和石头庙子组的沉积演化,得出益新矿区含煤岩系为石头河子组的滨湖—湖泊—湖泊三角洲沉积体系. 成煤作用主要为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。

Late Jurassic Sedimentary Evolution on Coal Bearing Rock System in Yixin Mine of Hegang Coal Field
Abstract:The author combines the characteristics of regional tectonic,reaserch and analysis the characteristic of formation、lithology、Lithofacies and Sedimentary Cycle on coal bearing rock system in Yixin mine, and then analyzed the sedimentary evolution of Shitouhezi group and Shitoumiaozi group in Yixin mine .The paper educed that coal bearing rock system Sedimentary environment is the lakeshore—lake—lake delta Sedimentary system during the Shitouhezi deposition period in Yixin mine. The mainly coal accumulation is the swamping of the lake delta and disappearance of lakes. Then, a large number plants flourish growth、dead、accumulation and formed thick coal seams.
Keywords: Yixin Mine Shitouhezi formation Sedimentary evolution
