摘　　要：大义山复式岩体内发育的云英岩脉和电英岩脉，锡矿化较强。而鳞云母黄玉云英岩、电气石云英岩、白云母云英岩、电英岩、蚀变细粒花岗岩、云英岩—似伟晶岩，亦与锡多金属矿密切有关。显而易见，云英岩化和电气石化是大义山岩体内锡矿的最佳找矿标志。Tin mineralization is developed strongly in the greisen dike and tourmaline-quartzite dike hosted in the Dayishan poly-granite, and the tin mineralization has closed relation with lepidolite-topaz-greisen, tourmaline-greisen, muscovite-greisen, tourmaline-quartzite, altered fine-granite and greisenpegmatite. Obviously, tourmalization and grenization is the best ore guide of prospecting for tin deposit in Dayishan poly-granite.
