摘　　要：芙蓉锡矿田位于炎陵-蓝山北东向重磁梯级带的中段南侧。锡矿产于骑田岭复式花岗岩体南部内外接触带,多呈脉状产出。锡矿体与围岩有明显的磁性、电性差异,物化探异常与矿体的空间分布有密切关系,综合异常的浓集部位,反映了矿体的分布位置。此规律对寻找新矿体和新锡矿产地具指导意义。The Furong tin ore field located at the south in the middle part of the Yanling - Lanshan northeast gradient zone of gravity magnetic anomaly. The tin deposits are occurred as the veins in the southern part of the Qitianling composite granite body and its contact zone. There are obvious differences in magnetic and electrical property contrast between the tin deposits and its country rocks. The geophysical and geochemical anomalies are closely related to the distribution of the tin deposits, and the tin deposits are distributed in the concentration place of the comprehensive anomalies. These laws have guiding significance for prospecting new tin deposits.
