摘要
伊宁盆地是新疆主要聚煤盆地之一,预测煤炭资源总量2178.8亿t。通过对含煤盆地岩石地层分析,发现研究区发育三套红层,即三叠系小泉沟群(T2-3xq)红层,侏罗系水西沟群(J1-2sh)红层及古近系红层,三套红层分属于两个构造层。根据红层与煤系地层的关系分析,认为古近系红层覆盖区最有可能发现隐伏的整装大煤田。查清红层的层序,对指导找煤及加速进行煤田地质勘查有着重要意义。
The Yining Basin is one of major coal-accumulating basins in Xinjiang with predicted total coal resources 217.88 billion tons. Through coal-beating basin lithostratigraphie analysis, found that there are three sets of red bed in the study area, namely Triassic Xiaoquangou Group (T2-3xq) red beds, Jurassic Shuixigou Group (JI-2sh) red beds and Paleogene red beds, the three sets belonging to two synthems. Based on relations between red beds and coal measures strata, considered that hidden intact large-scale coalfields could be found under the Paleogene red beds covering. So that to recognize red beds sequences has major significance in coal looking guiding and speeding up coalfield exploration.
