中文摘要：

对瑶上坑地区土壤元素含量进行数学地质分析及单元素异常评价可知,研究区土壤中Cu和Mo、Pb和Zn具有良好的亲和性,其中Cu和Mo的异常范围一致性较好,异常强度高,规模大,主要分布于岩体与老变质岩接触带两侧,可能与不同岩性界面充填的中高温成矿热液有关。研究区共圈定了4个土壤地球化学综合异常块段,对Ⅱ号综合异常块段进行工程查证,发现元素异常高值与与石英破碎带有关的张性断裂关系密切。建议对其他3个综合异常块段开展相关工程查证,从而确定各元素异常与北东向断裂构造、岩性接触带之间的关系。

英文摘要：

Yaoshangkeng area in eastern Yuhuashan volcanic basin lies in the northeastern part of the Qinzhou-Hangzhou metallogenic belt. The complex tectonic setting of the study area is favorable for mineralization. According to the result of mathematical analysis and single element anomalies,Cu has a close affinity with Mo,so do Pb and Zn. The copper anomaly area and molybdenum anomaly area,characterized by large size and high intensity,are distributed on both sides of the contact zones between magmatic rocks and metamorphic rocks,show good consistency with each other,and may be related to the medium-high temperature mineralized hydrothermal filling metasomatism on the lithologic interfaces. Four areas were selected as targets for further exploration,and anomaly verification for target area II shows that the strongest anomalies usually appear around the fractured quartz veins caused by extension fractures. In order to determine the major factors（ NE-trending faults or different lithological contact zones） that are responsible for element anomalies,the authors suggest the performance of relevant anomaly verification in the other three target areas.
