雷公山地区位于扬子准地台与华南褶皱带之过渡地带,发育加里东期由西向东运动的逆冲推覆型过渡性剪切带。该剪切带主要表现为一系列的劈理密集带、剪切褶皱、剪切透镜体、S—C构造、拉伸线理等构造形迹,并发育糜棱岩化岩石。其构造模式为受向面倾斜的主滑脱面控制,由一系列西倾东倒、上陡下缓、右旋逆冲的叠瓦状断裂、褶皱及过渡性剪切带构成逆冲推覆体;其形成时代为志留纪末的加里东运动时期;运动方式由西向东,形成深度在14km以上,其主滑脱面在三江─龙胜断裂带(在本区尚处地下深处)。由于燕山期由东向酉的逆冲推覆运动,将中深层次的构造形迹推到形成侏罗山式褶皱的地层之上,造成不同深度的陡、缓倾过渡性剪切带并列的格局。本区的锑、金、多金属矿的分布严格受过渡性剪切带的控制,矿体往往产于沿陡劈理裂隙充填的石英脉中,形成时代为加里东期。
The Leigongshan area is located in the transitional zone between the Yangtze Platform and the South China Fold Belt, and developed the thrust-nappe transitional shear zone moving from west to east during the Caledonian period. The shear zone is mainly characterized by a series of structural features such as cleavage intensive zones, shear folds, shear lenses, S-C tectonics and tensile line tectonics, and the development of mylonitized rocks. Its tectonic model is dominated by the main slip plane tilted toward the facet and is composed of a series of thrust-nappe bodies with a series of imbricate faults, fold and transitional shear zones with westward dip, eastward dip, right-lateral thrust, ; Its formation era is the Caledonian period at the end of Silurian. Its movement mode extends from west to east, forming a depth of more than 14km. Its main slip surface is in the Sanjiang-Longsheng fault zone, which is still deep underground. Due to the thrusting thrust from the east to the unitary during the Yanshanian period, the middle-deep tectonic trace was pushed to the formation of the Jurassic fold, resulting in the parallel pattern of steep and gentle transitional shear zones at different depths . The distribution of antimony, gold and polymetallic ores in this area is strictly controlled by the transitional shear zone. Ore bodies are often produced in quartz veins filling along steep cleavage and fissures, forming the Caledonian era.
