为探究不同类型锡矿床所反映出的自然重砂矿物组合特征，统计了云南、福建、江西、浙江、湖南、青海和广西7省共35个典型锡矿床的自然重砂情况，通过计算和分析各自然重砂矿物在所对应类型矿床中的报出频率，得出矽卡岩型、热液脉型和斑岩型3种锡矿所对应的自然重砂矿物组合。所反映出的重砂矿物组合既有相似之处，如均出现锡石+白钨矿（或黑钨矿）的矿物组合，亦反映出不相同的地方，如矽卡岩型锡矿石榴子石报出率高，斑岩型锡矿锆石报出率高等。因此，按照矿床类型建立的自然重砂矿物组合对于建立自然重砂找矿模型具有重要意义。

To investigate the combination characteristics of natural heavy minerals reflected by different types of tin deposits, the au?thors gathered statistic data of the occurrence situation of 35 typical tungsten deposits (mining areas) from seven provinces or autono?mous region of Yunnan, Fujian, Jiangxi, Zhejiang, Hunan, Qinghai and Guangxi, calculated the frequencies of occurrence of many kinds of natural heavy minerals, and worked out the mineral assemblages of skarn, hydrothermal and porphyry tin deposits as well as the typomorphic minerals. The results show that they have a certain sameness in mineral association, such as the existence of cassiter?ite+scheelite (or wolframite) assemblage without exception, and also show some differences;for example, the frequency of occur?rence of garnet is relatively high for the skarn type tin deposit, whereas he frequency of occurrence of zircon is relatively high for the porphyry type tin deposit. The natural heavy mineral assemblage based on deposit type is of great significance for the formulation of the ore-prospecting model of natural heavy minerals.
