Screening and potential analysis of the target area of the Yue'e tin-copper polymetallic deposit in Xiengkhouang,Laos
The Yue'e copper-tin polymetallic deposit in Xiengkhouang,Laos is located in the western part of the Xiengkhouang-Vietnam Changshan regional tectonic belt of the important iron,copper and gold poly-metallic metallogenic belt in Southeast Asia.The deposit is covered by thick vegetation and Quaternary,and its the degree of research is low.By analyzing the data of the mining area,the 1∶25,000 ditch system sec-ondary halo measurement was carried out,the target area was screened,and the prospecting potential was e-valuated.The results show that the skarn type copper polymetallic deposit and the tectonic hydrothermal al-tered tin polymetallic deposit are the prospecting prospects for the two different types of deposits in the min-ing area.The mineralization is closely related to magmatic rocks,and the NE-trending fault is an important ore-controlling and ore-bearing structure in this area.The shallow prospecting should be carried out around the NE-trending faults.The deep part may be the contact alteration area between the surrounding rock and the rock mass,which is the main prospecting direction.By carrying out 1∶25,000 ditch system secondary halo measurement,4 prospecting target areas and 10 prospecting prospect areas were selected.Combined with anomaly and engineering verification,1 medium-sized tin polymetallic deposit and 1 small and rich skarn copper ore body were found.
