The anomalies determined using a soil geochemical survey and prospecting model of the Matou gold deposit in Sichuan Province

摘要: 四川马头金矿位于冕宁—盐源走滑造山带,属深切割第四系覆盖区,地表找矿线索有限。本次找矿阶段通过1:10 000土壤地球化学测量工作,圈定了综合异常区,并实施槽探工程验证,发现了金矿体,取得了较好的找矿效果。同时,结合工作区地质、地球化学异常特征,建立了以HT3异常区为主体的地质—地球化学找矿模型,并提出了下一步找矿方向。Abstract: The Matou gold deposit is located in the Mianning-Yanyuan strike-slip orogenic belt and is part of the deeply cut Quaternary coverage area and, thus, has limited surface prospecting clues. In this prospecting stage, a comprehensive anomaly area was delineated through the 1:10 000 soil geochemical survey. Then, gold ore bodies were discovered through trenching engineering, indicating excellent prospecting performance. Moreover, this study established a geological-geochemical prospecting model dominated by the HT3 anomaly area by combining the geological and geochemical anomalies in the work area. Finally, the next prospecting direction was proposed.
