Summary:On the basis of such data as metallogenic geological condition, geneses of ore deposits, tin rock types and material components, tin ore deposits (occurrences) in the Zhejiang region are grouped into six types, i.e., porphyry type, skarn type, greisen type, cassiterite-quartz vein type, cassiterite-sulfide type, and placer. Geotectonically, tin ore deposits (occurrences) in this region were mainly formed in diwa stage from the Mesozoic-Cenozoic. The clastic formation of geosynclinal type, the carbonate formation of platform type and the acidic volcanic formation of diwa stage are respectively favorable tectonic horizons for tin ore formations of lithophile type, skarn type tin deposits, and tin ore formations of porphyry or lithophile type. In tectonic units, the tin ore formations of lithophile type are mainly distributed in the Chencai-Longquan geodome, while the tin ore formations of siderophile type and sulphophile type occur mainly in the Fuyang-Kaihua diwa subsidence zone. In infrastructure, the tin ore deposits (occurrences) are concentrated in plunging positions of basement uplift (western Zhejiang uplift) and the depths of basement depressions (eastern Zhejiang depression). Tin ore deposits (occurrences) and tin-polymetallogenic factor areas in Zhejiang province all lie on the southwest side of the NW-trending Wenzhoujinhua-Jiande fault line, and this makes up another feature of tectonic distribution of tin. In view of the structural and formational control of the mode of occurrence of tin, the author holds that the Wuao-Yangbin area seems to be the most favorable area for the prospecting of tin deposits in Zhejiang province.
