摘要
湘中涟邵煤田北段发育由下石炭统测水煤系组成的寒婆坳向斜,通过对向斜东西两翼构造的研究,发现了一条与岩浆侵入具有成生联系的逆冲推覆构造F1,并建立了一个新的逆冲推覆构造模型。根据F1发育特征可分为三个带:岩浆膨胀带、挤压运移带及锋带。F1下盘地层产状平缓,煤与石墨矿可能保存完好,初步估算在垂深600m以浅,其资源量在7000万t以上。
Based on geological structure research in the western and eastern wings of the Hanpoao syncline composed of the Carboniferous Ceshui coal measures, a thrust fault F1 genetically related to magmatic intrusion has been found, thus a new thrust nappe tectonic model set up. Since the occurrence of the strata in lying wall of F1 is gentle, the coal seams and graphite may preserve in good condition. According to a preliminary estimation, the resources will be over 70 million ton above 600m depth.
