禾尚田钨锡矿床产于上泥盆统天子岭组碳酸盐岩中，矿床类型为石英细脉带型，脉体具有倾向上延伸长、厚度变化不大等特征。根据区域重、磁及化探资料推测，在九峰岩体与大东山岩体之间的瑶山复背斜，两岩体深部几乎可以相连，矿区深部可能有隐伏岩体，且矿区所做的重力剖面测量工作发现矿区处于隐伏岩体的上凸部位；另外，钨锡矿床的成矿时代与其南北两侧的大东山岩体、九峰岩体时代基本一致，且该时期又为粤北乃至整个南岭地区成岩成矿高峰期；说明禾尚田矿区钨锡矿的成矿与深部的隐伏岩体关系密切，基于此，建立了禾尚田钨锡矿床的成矿模式，为后续的勘查工作提供新思路。

Heshangtian W-Sn deposit occurred in the Upper Devonian Tianziling Formation carbonate rocks is quartz-veinlet-belt type deposit. The ore veins have a tendency of extension elongation, thickness change charac-teristics. According to analysis the regional gravity survey, magnetic and geochemical data, the intrusion of Jiufeng and Dasongshan are connected together at deep of Yaoshan anticlinorium, and the ore bodies are speculation in convex position of concealed intrusion. The mineralization time of Heshangtian W-Sn deposit is similar to intru-sion time of Jiufeng and Dadongshan intrusion when is the peak of mineralization of northern Guangdong province, even to the whole Nanling Range, which indicated the W-Sn mineralization is closely related to concealed intru-sion. The metallogeinc model of Heshangtian W-Sn deposit are established through the above analysis and maybe useful for the future prospecting in this area.
