中国东北部(包括黑龙江、吉林、辽宁三省和内蒙古自治区东部)的广大地区中,已发现的晚侏罗世——早白垩世煤盆地有数十个之多,盆地都属断陷类型,聚煤量丰富,以含有巨厚煤层为特征,煤层累计厚度有超过240米者,著名的有阜新、霍林河、元宝山、平庄、伊敏、扎赉诺尔、铁法和胜利等煤盆地。这些盆地的沉积、构造和含煤性很有特色并有共性,作者选择了典型盆地从盆地的几何形态和构造格架、沉积序列、地层格架、沉积相的组成和空间配置以及聚煤特征等多方面进行研究,并与区域内同类型盆地和我国一些现代断陷湖盆做了广泛对比,试图概括此类盆地的沉积模式和构造演化特征,以用于新区预测和勘探。
In the vast area of northeastern China (including the three provinces of Heilongjiang, Jilin, Liaoning and the Inner Mongolia Autonomous Region), there are dozens of Late Jurassic-Early Cretaceous coal basins discovered, all of which belonged to faulted type and poly The coal is rich in coal and is characterized by a thick coal seam. The total thickness of the coal seam is more than 240 meters. The famous coal bases such as Fuxin, Huolin River, Yuanbaoshan, Pingzhuang, Yimin, Zhalainuoer, Tiefa and Shengli coal basins . The sedimentation, tectonics and coal-bearing properties of these basins are very characteristic and common. The author chose the typical basin from the basin geometry and tectonic framework, sedimentary sequence, stratigraphic framework, composition and spatial distribution of sedimentary facies, And other aspects of the study and with the same type of basins in the region and some modern fault basin lakes in China made a comparison, trying to summarize the sedimentary patterns and tectonic evolution characteristics of these basins for the new area prediction and exploration.
