内蒙古甲生盘铅锌硫矿床成因探讨

A Discuss Genesis of Jiashengpan Lead, Zinc and Sulphur Deposit in Inner Mongolia

甲生盘铅锌硫矿床是一个大型层控矿床，赋存于中元古界渣尔泰山群阿古鲁沟组白云质灰岩、砂质白云岩之中，属海底火山喷气—沉积成因。该碳酸盐岩为一套滨海—浅海碳酸盐台地相沉积，同生滑动现象十分发育，存在着古同生断裂，为火山喷气提供了通道。台地坡底沟相这一独特的环境，又为成矿物质的富集提供良好的场所。

Jiashengpan lead,zinc and sulphur deposit is a large stratabound deposit which is occurred in dolomitic limestone,sandy dolomite of Agulugou formation of Chaertaishan group of middle proterozoic Earthen.The deposit belongs to submarine volcanic exhalation-sedimentary genesis.The carbonate rock is a suite of littoral-shallow sea carbonate platform facial sediment,contemporaneous sliding was very development.It exists in palaeocontemporaneous fault and supply channels for volcanic exhalation.The platform slope bottom facies that a well position to supply the sandy material of rich is a specially environment.
