摘要:
瓦恰一带地处中国西部重要成矿带，矿产资源丰富，具备良好的成矿地质条件。基于1∶5万水系沉积物测量，系统分析了瓦恰一带 Cu、Pb、Zn等 9种元素的化探异常特征，圈定单元素异常115处、综合异常 9处。结合地质背景对化探异常进行综合评价，通过异常查证，发现欠孜拉夫铅锌铜矿床。通过系统的化探异常评价与找矿效果分析，建立适用的成矿模式。研究结果表明，欠孜拉夫铅锌铜矿床的发现不仅验证了 1∶5万化探异常评价方法的有效性，也为类似地质环境下的化探异常评价提供了新的思路和方法。通过对控矿地质因素及成矿地质特征研究，成功建立了瓦恰岛弧层控-热液叠加型铅锌铜成矿模式，对区域后续矿产勘查具有重要指导意义。

Abstract:
The Waqia area is situated within an important metallogenic belt in western China, characterized byabundant mineral resources and favorable geological conditions for mineralization. Based on 1∶50 000 stream sedimentsurvey data, the geochemical prospecting anomaly characteristics of 9 elements, including Cu, Pb, and Zn, were system⁃atically analyzed, leading to the delineation of 115 single⁃element anomalies and 9 comprehensive anomalies. Integratedevaluation of these geochemical prospecting anomalies within the geological context was conducted, and the QianzilafuPb-Zn-Cu Deposit was discovered through anomaly verification. By systematically evaluating geochemical prospectinganomalies and analyzing the prospecting effect, an applicable metallogenic model was established. Results indicate thatthe discovery of the Qianzilafu Deposit validates the effectiveness of the 1∶50 000 geochemical prospecting anomalyevaluation method and provides new insights and methodologies for evaluating geochemical prospecting anomalies insimilar geological environments. By studying ore⁃controlling geological factors and metallogenic characteristics, a strat⁃abound and hydrothermal superimposed Pb-Zn-Cu metallogenic model for the Waqia island arc was successfully estab⁃lished, offering significant guidance for subsequent regional mineral exploration.
