福建大田广平推覆构造与隐伏煤、多金属矿

Guangping Nappe Structures,Hidden Coals and Polymetallic Ores in Datian County,Fujian Province

广平推覆构造是与广平—龙凤场平卧向斜相伴产出的褶皱推覆构造,是由一组大致沿石炭—二叠纪不同地层岩性界面发育的滑脱断层和沿外来岩系底界分布的逆冲推覆断层构成。推覆构造是内生铁硫铅锌多金属矿的重要控矿构造,同时,对二叠纪含煤地层的保存和破坏有重要作用。研究和分析推覆构造特性,对于我省寻找隐伏矿产有重大意义。

the Guangping nappe structures,with the concomitance of the Guangping-Longfengchang horizontal syncline,are comprised of a group of the decollement faults developed along the Carboniferous and Permian lithologic interfaces and the thrust nappe faults along the bottom boundary of exotic rock series.The nappe structure is one of important ore-controlled structures forming the endogenic polymetallic ores such as iron,led and zinc and plays an important role in the preservation and destruction of Permian coal-bearing strata.Study on the nappe structures is great significance in searching for hidden ores in Fujian Province.
