统计浙江、湖南、江西、湖北、新疆、青海、云南、广西、福建、河南、贵州、安徽、广东共计13个省（自治区）61个典型钨矿床（矿区）的自然重砂矿物报出情况，计算各重砂矿物的报出频率，分析得出矽卡岩型、热液型和斑岩型3种类型钨矿床所对应的自然重砂矿物组合及标型矿物组合。结果表明，不同类型的矿物组合既有相似处也有各自的代表标型。如此按照矿床类型建立的自然重砂矿物组合及其含量变化，对建立自然重砂找矿模型具有重要意义。

To investigate the combination characteristics of the natural placer minerals reflected by different types of tungsten depos?its, the authors gathered statistic data of the occurrence situation of 61 typical tungsten deposits (mining areas) from 13 provinces or autonomous region, i.e., Zhejiang, Hunan, Jiangxi, Hubei, Xinjiang, Qinghai, Yunnan, Guangxi, Fujian, Henan, Guizhou, Anhui and Guangdong, calculated the frequencies of occurrence of many kinds of natural heavy minerals, and worked out the mineral assem?blage of skarn, hydrothermal and porphyry tungsten as well as the typomorphic minerals. The results indicate that different types of mineral assemblages has both similarities and their respective standard types. The assemblage of natural heavy mineral and its content variation established by the deposit type are of great significance for the building of natural placer prospecting model.
