摘要
湖南界牌岭锡矿床蚀变矿化可分为条纹状云母萤石岩化—铍矿化带,细脉状云母萤石化—铅锌矿化带、黄玉—萤石—云英岩化—锡铜锌多金属矿化带和弱—无蚀变矿化带.不同蚀变矿化带物质组分迁移规律有不同的特点.其成矿物质主要来源于花岗斑岩,该矿床是与陆壳重熔型花岗岩类斑岩体有成因联系的斑岩型锡矿床.
The alteration-mineralization zoning in Jiepailing tin ore deposit can be divided into ribbon mica-fluoritization-Be mineralization zone, veinlet mica-fluoritization Pb and Zn mineralization zone, topoz-fluorite-greisenization Sn, Cu and Zn mineralization zone, and weak alteration-unaltered zone. It is characterized that the material component migration regularities of each alteration mineralization zones are different, ore-forming material are mainly derived from granite-porphyry. It is suggested that this porphyry tin deposit is genetically related to continental crust remelted granite-porphyry.
