摘要：

锡石自然重砂测量对寻找锡矿有利。利用已有自然重砂测量数据，可知区内主要的自然重砂矿物组合是锡石+钨族矿物+铅族矿物+黄铁矿+磁铁矿等，对比腾冲梁河地区典型矿床的矿石矿物与自然重砂矿物的组合特征，总结出自然重砂组合对锡矿体的响应程度，自然重砂异常与矿床有极好的相关性；分析了自然重砂矿物组合所蕴含的矿床成因类型信息，有利于判定锡矿床的成因类型和成矿温度，便于快速锁定有效的找矿模型；结合岩浆岩、地层和构造等地质因素，以及地形和水系特征，在该地区圈定出自然重砂异常区，为下一步找矿勘查提出了参考资料。

Abstract:

Cassiterite heavy minerals are indicator for tin deposits. The heavy minerals data shows a mineral combination of cassiterite, tungsten, lead, pyrite and magnetite in work area, which is compared with ore minerals and heavy minerals of Lianghe’s typical deposits. Indication of heavy minerals to tin deposits is summarized by their well relativity. This paper analyzes the deposit genesis implied from heavy minerals combination that can be used to determine the mineralization types and temperature and to find out a workable exploration model. Heavy minerals anomaly zones which are outlined based on magma, strata, structure, terrain and streams provide references for next exploration.

Key words: heavy minerals, Lianghe, Tengchong, comparison, combined features, anomaly zone
