摘　　要：通过对大义山锡多金属矿田基本地质特征和成矿规律的综合研究,查明锡多金属矿化主要产于大义山花岗岩体的内外接触带中,阐述了矿体分布与定位规律,分析了赋锡多金属矿花岗岩特征、断裂构造、褶皱和岩体构造对矿体形成、演化与就位的制约关系。认为成矿作用主要与中侏罗世 -晚侏罗世的花岗质岩浆活动相关,并探讨了大义山岩体和锡多金属矿成岩成矿机制及该锡多金属矿的找矿方向。According to the integrated studies of general geological characteristics and metallogenic regularities, it is shown that the Sn-Pb-Zn-Sb-W polymetallic mineralization is mainly distributed along inside or outside contacting zone of Dayishan granite body. Ore body distribution pattern and ore fixing regularities are stated. Tin-rich granite characters, faults, folds, massif structure and their restraints on formation, evolution and location of ore bodies are analyzed. It is suggested that tin mineralization is related with middle-late Jurassic granite magmatism. Dayishan granite genesis and tin prospecting potentiality are lastly discussed.
