| Abstract: | The Heizhushan Area is located in the Eastern Kunlun Qimantag-Dulan Hualixi period iron，cobalt，copper，lead，zinc，tin，wollastonite（antimony，bismuth） metallogenic belt（Ⅲ11）-Ulan-Uzhuer The copper（tin） metallogenic sub-zone（Ⅳ15） of the Valixian period，and has superior metallogenic geological conditions.In order to better guide the regional prospecting work and delineate the prospecting prediction target area，this study carried out a 1:25 000 river sediment measurement in the Heizhushan Area，and used factor analysis and R-type cluster analysis to analyze the test results.Based on the analysis，7 comprehensive anomalies have been delineated based on the mineralization geological characteristics of the study area，of which AS2 and AS4 are relatively strong.Through the abnormality verification of the AS4 and AS2 abnormal areas，a lead-zinc-silver barite ore body and a quartz barite vein were discovered.Combining the regional tectonic background，mineralization conditions，resource potential and other factors，it is believed that the AS2 and AS4 anomalous areas delineated by river sediment measurement have good prospecting prospects.Among them，the discovery of quartz barite veins in the abnormal area of AS2 provides a new prospecting direction for the research area to find the low-temperature hydrothermal quartz barite deposits in micro-cracks. |
