| 摘 要： | 大厂锡多金属矿床是世界闻名的超大型矿床,笔者从构造控矿、同位素测年、流体包裹体、成矿物质来源及同生沉积成矿等五个方面综述了近半个世纪来该矿床的一些研究进展,并结合近年来野外调查研究,认为大厂锡多金属矿床属后生成因,成岩、成矿是燕山晚期同一构造-热事件的产物,成矿过程中有幔源流体的显著参与,矿体产出形态的空间变化受不同深度的构造特征所控制。

| Abstract: | The Dachang tin-polymetallic deposit in Guangxi is one of the largest tin deposits all over the world.However,this deposit has long been in debate as to its origin.There are different opinions,one is that the Dachang deposit was formed by replacement of hydrothermal solution originated from Yanshanian granites,another consider that this deposit was formed by submarine exhalation during the Devonian.This paper presents some new data by recent study of structure control-rule,isotopic geochronology,the fluid inclusions,the mineralization material origin isotopic labeling and so on,based on these data and field investigation,the authors regard both vein-type orebody and strtiform orebody in Dachang area were formed at the Late Yanshannian instead of the Devonian,and mantle fluids were involved in the metallogenic process,and different occurrence modes of orebody are controlled by the different structural assemble style. |
