鄂东南地区构造特征及其控岩控矿规律

鄂东南地区经历了印支期、燕山期、四川期构造运动。印支期形成了一系列道冲—滑覆构造；燕山期形成了扭动变形系列及盆岭构造，四川期造成区内上挤下张的应力环境。燕山—四川期构造作用造就了岩浆上侵的构造环境、控制了岩浆侵位方式及成矿作用。印支期构造则控制了岩体、矿体在空间的分布，不同级别的构造单元控制了不同级别的岩浆岩带及成矿单元，矿床体则主要赋存于逆冲—滑覆构造系列中。

CHARACTERISTICS OF THE STRUCTURES AND THEIR ROCK AND ORE CONTROL LOW

In southeastern Hubei, as a result of the tectonic movements, a series of thrust detachment structures were formed in Indosinian, the torsional deformation series and the basin and range structures were formed in Yanshanian and stress environment of upper compressing and lower tensiling was formed in Sichuanian. The tectonism from Yanshanian to Sichuanian has built up the tectonic environment for the magmatic intruxion and controled the magmatic emplacement way and metallogenesis. The structures in Indosinian controls the spacial distribution of the rocks and ore bodies and different classes of tectonic elements controls different classes of magmatic rock belts and ore-formig units respectively. The ore deposit bodies are mainly occured in the thrust -detachment structural series.
