山东栖霞地区水系沉积物地球化学特征及找矿预测

Geochemical Characteristics of Stream Sediments and Metallogenic Prognosis in Qixia Area of Shandong Province

摘要:

在开展1∶5万水系沉积物测量工作基础上，对栖霞地区的元素分布特征、元素富集和分异特征、元素相关性分析、单元素异常特征等地球化学特征进行了初步分析。结合地质成矿背景，根据化探异常和元素成矿特征圈定27处组合异常，并进行了综合分析和异常查证，验证多处异常具有较好的蚀变矿化，其中在AS21区发现5条蚀变带，4条金矿（化）体，说明该区具有良好的找矿前景。

Abstract:

Based on stream sediment survey with the scale of 1∶50000, geochemical characteristics have been preliminarily analyzed, such as element distribution characteristics, element enrichment and differentiation characteristics, element correlation analysis and element anomalies. According to anomalies and elements mineralization characteristics in combination with oreforming geological setting, 27 composite anomalies have been circled. Comprehensive analysis and anomaly verification have been carried out, and good alteration and mineralization in many anomalies have been verified. 5 alteration zones and 4 gold ore (mineralized) bodies have been found in AS21 area. It is indicated that there has a good prospecting potential in this area.
