摘要
The Huangling anticline,situated in the middle Yangtze block with anticlinal uplift structures,is a key region to understanding the distribution and controlling factors of lead-zinc deposits.In this paper,from the perspective of regional sedimentary-tectonic evolution,the tectonic evolution process of the Huangling anticline were discussed.Results of statistical analysis of low-temperature thermochronological data show that there were mainly four different uplift stages in the Huangling anticline area since the Mesozoic,which were closely related to the regional tectonic events.In Middle-Triassic to Middle-Jurassic period(240-160 Ma),there was no tectonic deformation around the Huangling anticline,which was mainly affected by basal irregular activity control and appeared slow differential uplifting,characterized by multiple formation of the parallel unconformity and paleogeographic pattern differences.The Late-Jurassic to early stage of Late-Cretaceous(160-95 Ma) tectonothermal event,by the effect of Qinling-Dabie orogenic belt and the Xuefeng-Jiangnan intra-continental fold and thrust belt bidirectional extrusion,the middle and upper Yangtze basin sedimentary center and Yanshanian arc hedge tectonic belts were converged migration from east to west,and the NNE-trend Huangling anticline was formed as an independent structural unit and assumed strong uplifting.At the Late-Cretaceous to Middle-Eocene stage(95-45 Ma),Huangling anticline was relatively stable or slowly uplift.Since the late Eocene(45-0 Ma),with the main tectonic events of the angular unconformity between the Neogene and Paleogene and corresponding tectonic deformation,including the Huangling anticline,the Middle-Upper Yangtze region was overall suffered a rapid uplift denudation under the compression with NE-SW direction.Among them,the Late-Jurassic to Early-Cretaceous was an important period of the formation and stereotyped structural framework of Huangling anticline.
