| 摘 要： | 至2018年底,湖北省已探明资源储量矿产有91个矿种及1418个矿产地。本文采用最新同位素年代学数据,讨论了吕梁旋回、晋宁旋回、加里东旋回、印支旋回、燕山旋回和喜马拉雅旋回等6个构造旋回的构造-地层-岩浆时空演化过程,探讨了各构造旋回演化过程中发生的岩浆成矿作用、沉积成矿作用、变质成矿作用、表生成矿作用、流体成矿作用,划定了6个成矿系列组和32个矿床成矿(亚)系列,总结了成矿规律。湖北省有3个爆发性成矿时期:早震旦世在神农架—宜昌—钟祥地区生物化学沉积形成了磷矿矿集区,晚侏罗世到早白垩世在鄂东南地区发生了与岩浆成矿作用有关的大规模铁铜多金属成矿作用,白垩纪—古近纪在江汉盆地沉积形成了石膏-盐-石油等矿床。

| Abstract: | By the end of 2018, proven resource reserves in the Hubei Province included 91 minerals and 1418 mines. Based on the latest radiometric dates, this paper discusses the tectonic- stratigraphic- magmatic spatiotemporal evolution of the six tectonic stages including the Lvliang, the Jinning, the Caledonian, the Indosinian, the Yanshanian, and the Himalayan. Various processes including magmatic mineralization, sedimentary metallogenesis, metamorphic metallogenesis, surface metallogenesis, as well as fluid metallogenesis involved in their evolution are discussed. Furthermore, 6 groups of minerogenetic series of deposits and 32 minerogenetic (sub- ) series were identified, and their metallogenic regularity summarized. Three explosive mineralization periods have been determined in Hubei. Phosphorous deposits were mineralized by biochemical processes in the Baokang- Shengnongjia- Yichang- Zhongxiang area during the Early Sinian. From late Jurassic to early Cretaceous, large- scale Fe- Cu- Au polymetallic metallogenesis related to magmatic metallogenesis occurred in the southeastern Hubei. Gypsum- salt- petroleum were deposited in the Jianghan basin during the Cretaceous- Paleogene. |
