中酸性小岩体的内部及附近的围岩中常形成与岩浆岩体有关的大型、超大型矿床,已成为找矿工作的一个重点方向。由于地质工作程度的限制,中酸性小岩体易被遗漏,严重制约了该类型矿化的发现。在新疆西准噶尔达尔布特断裂带下盘加甫沙尔苏地区找矿工作中,通过综合分析,提出了以遥感手段为主导的中酸性小岩体型矿化找矿模型:利用ASTER数据,通过图像增强处理、图像解译识别中酸性小岩体并提取蚀变遥感异常,结合地质、化探信息综合分析后确定重点检查区域。野外检查发现了加甫沙尔苏斑岩型钼矿化点,证实了该方法的有效性。该方法可以为西部地区中酸性小岩体型矿产资源勘查提供借鉴。
The formation of large and superlarge deposits related to magmatic rocks in and around the medium acidic small rock mass has become a focus of prospecting. Due to the limited degree of geological work, small-medium acidic rocks are easily missed and the discovery of this type of mineralization is severely restricted. In the prospecting work of the Xiapanbu fault zone in Xizhunar, Xinjiang, and the prospecting of the Funchal Su area, a medium-acidic lithofacies mineralization prospecting model dominated by remote sensing was proposed through comprehensive analysis: using ASTER data, Enhanced processing and interpretation of small acidic rocks in the image interpretation and extraction of remote sensing anomalies, combined with geological, geochemical information comprehensive analysis to determine the key inspection area. The field inspection revealed the Mo-Shacha porphyry molybdenum mineralization sites, confirming the effectiveness of the method. The method can provide references for the investigation of medium and small rock mass mineral resources in the western region.
