摘要
为全面认识黑龙江省东部珍子山组含煤岩系沉积体系、沉积环境的平面和垂向展布特征以及聚煤特征.采用地质剖面观察及钻孔岩心描述等方法,结合岩石薄片分析,研究了黑龙江东部晚石炭世-早二叠世珍子山组含煤地层的沉积环境和聚煤特征.结果表明:珍子山组岩相类型以砂岩相和黏土岩相为主,沉积环境主要为河流相、滨浅湖相和泥炭沼泽相;厚煤层主要形成在滨浅湖相,位于高位体系域早期和晚期.
Abstract
This paper is focused on exploring the plane and vertical distribution characteristics and coal accumulation features behind sedimentary system and sedimentary environment.The study involves using geological cross-section observations,and drillingcore descriptions,based on the analysis of rock thin-section,analyzing the sedimentary environment and coal accumulation features of the coal-bearing strata of Zhenzishan formationin the late Carboniferous to early Permian in eastern area of Heilongjiang Province.The results indicate that the main components of the lithofacies types of the Zhenzishan forma-tion are the sandstone and mudstone,the sedimentary environments primarily characterized by fluvial fa-cies,marginal shallow lake facies,and peat swamp facies.Thick coal seams are predominantly generited in the marginal shallow lake facies,and located in the early and late stages of HST.
