西昆仑落石沟一带铅锌矿成矿特征及区域预测

Abstract

Abstract:

Sixteen deposits, including iron and base metal, copper and lead-zinc have been found in high potential west Kunlun area，an important metallogenic belt in southwestern Xinjiang. Based on the study of the Baotashan and Luoshigou lead-zinc deposits and gravity, magnetic, chemistry and remote sense information, a regional evaluation conceptual model has been set up, regional ore-controlling law of lead-zinc deposits has been summarized and the predictive components have been determined by the present authors. Using weights of evidence law and 12 variables from geology, geochemistry, geophysics, and remote sense, the mineralized posteriori probability is calculated and five smallest predicted areas are delineated by the present authors.Through summarising the geological constrains of lead-zinc deposits, it is concluded that the Luoshigou area of western Kunlun is the most favorable for looking for hydrothermal lead-zinc deposits.

Key words: Luoshigou area, lead-zinc deposit, metallogenic rules, weights of evidence law, geological constrains, ore-searching and prediction
