中文摘要：

自然重砂测量是矿产勘查的重要手段之一，提取自然重砂异常中的矿化信息与区域地质、成矿事件之间的内在联系，对揭示区域成矿规律和预测潜在矿床具有重要的意义。云南西邑铅锌矿床是全国资源潜力评价中，通过自然重砂异常并结合其他找矿方法实现找矿突破的成功案例。报道了西邑铅锌矿床自然重砂异常的基本特征，探讨了矿床有关自然重砂异常特征及其在西邑铅锌矿找矿突破过程中的重要作用。

英文摘要：

Natural heavy mineral survey is one of the important methods for mineral exploration. It is significant to extract the information of heavy mineral anomalies and its intrinsic link with regional geology and mineralization for revealing the regional metallogenic regularity and predicting potential deposits. The Xiyi Pb-Zn deposit is a case of successful ore-prospecting breakthrough based on the anomalies of heavy minerals in combination with other prospecting methods. This paper reports the basic characteristics of the anomalies of heavy minerals in the Xiyi Pb-Zn deposit and the important role of these anomalies in the breakthrough of the prospecting work in the Xiyi Pb-Zn deposit.
