摘要墨江金厂位于哀牢山成矿带上,是我国西南地区重要的金镍矿床之一。为掌握墨江金厂外围找矿潜力,在观音山地区开展土壤地球化学测量工作,研究土壤中As、Au、Co、Cu、Ni、Sb、V、W、Ti元素的分布特征。基于区内成矿地质背景,运用聚类分析、冷热点分析和因子分析等方法,归纳总结区内元素成矿规律,共圈定6个综合异常。研究结果表明,Sb、As、Au、Cu、V、Ni在该区域较为富集,Au、Ni高值众多,富集程度强烈,具有局部富集成矿的可能。其中Au与其他元素相关性较弱,成矿具有多期性和复杂性,Co、Ni常伴生于岩体外接触带附近,与超基性岩体关系紧密。揭示了观音山地区具有较好的找矿潜力,应以金矿为主攻矿种,同时兼顾砷锑矿和钴镍矿。研究结果可为在区域内开展新一轮找矿突破战略行动指明找矿方向。

Abstract：Jin Mountain in Mojiang is located within the mineralization belt of the Ailao Mountains, and it is a significant gold-nickel deposit in Southwest China. To assess the prospecting potential in peripheral Jin Mountain of Mojiang, the authors performed soil geochemical analyses in Guanyin Mountain area, focusing on the distribution characteristics of elements such as arsenic (As), gold (Au), cobalt (Co), copper (Cu), nickel (Ni), antimony (Sb), vanadium (V), tungsten (W), and titanium (Ti) within the soil matrix. Based on the metallogenic geological background in the area, the authors summarized the mineralization patterns of these elements and delineated 6 synthetic anomalies, using cluster analysis, hot and cold spot analysis, and factor analysis. These findings reveal a relative enrichment of Sb, As, Au, Cu, V, and Ni in the area, with particularly high concentrations of Au and Ni, indicating a pronounced degree of enrichment and potential for localized mineralization. Notably, Au exhibits a weaker correlation with other elements, suggesting a complex and multi-stage mineralization process. Conversely, Co and Ni frequently occurred in proximity to the contact zones of rock bodies, and are closely associated with ultramafic rock formations.It is indicated that Guanyin Mountain area has good prospecting potential, and gold mine should be primarily targeted, and arsenic-antimony and cobalt-nickel deposits in the second place. This research could provide the prospecting direction for the new round of strategic action for breakthrough in prospecting in this region.
