Abstract: In order to search for gold-bearing alteration rocks-type gold deposits in the Southern An⁃ hui Province region，a pre-exploration of gold and multi-metallic deposits was conducted in the Baowujian area of Shexian County. Comprehensive collection of previous geological and mineral research data within the area was carried out，and based on comprehensive analysis，1∶10 000 and 1∶25 000 special geologi⁃ cal surveys，1∶10 000 geological profile surveys and soil geochemical surveys，1∶5 000 geological geo⁃ physical profile surveys，electrical sounding，trenching，drilling and electrical well logging were imple⁃ mented in this area. After conducting 1∶50 000 geochemical exploration anomaly verification in this area， the best drilling sites were selected for verification，providing a basis for the next comprehensive explora⁃ tion work. The study investigated the gold deposits (alteration) bodies，gold ore characteristics，rock altera⁃ tion and controlling factors in the area，preliminarily identified the controlling strata，structural morpholo⁃ gy，magmatic rocks and mineralization characteristics in the area，obtained new magnetic and electrical anomaly data，revealed the deep structural styles and the causes of geophysical anomaly，identified multi⁃ ple geochemical anomaly areas，discovered multiple high-value gold points and deep gold mineralization bodies. Based on the comprehensive results of geology，geophysical exploration and drilling，and after com⁃ parison with typical ore deposits in the region，the metallogenic type of gold deposits in the area was pre⁃ liminarily determined，the exploration markers were established，it was clarified that the area has a good prospect for exploration，and the exploration target areas were delineated.
