| Abstract: | Tibet Dangxiong Lawu copper zinc ore diposit tectonic locaed in the middle northern section of oregon Ximalayan tectonic areas.In discussing the ore-forming geological background,based on geological characteristics were studied.The ore bodies are distributed in layered skarn of day imnah anticline axis turning side of upper carboniferous Permian to gu group.relatively uniform type mineralization.Wall-rock alteration formation can be roughly divided into metallogenic metallogenic epoch of prosync and post periods.Through analysis and study of the ore-controlling factors,ree distribution and fluid inclusion,stable isotopes characteristics,summarizes the mineralization mechanism of the ore deposit.meanwhile points out the ore-prospecting criteria. |
