摘　　要："东岩墙"位于广西大厂铜坑-长坡锡矿(大厂主体矿山)东侧,一直被认为是单一花岗斑岩岩墙。文章研究认为"东岩墙"除了花岗斑岩外,还有次玄武岩、闪长玢岩及构造破碎带。"东岩墙"是一SN向、多期次构造-岩浆活动带,是大厂锡矿的主要控岩控矿构造。East dyke is located at Tongkeng -- Changpo tin mine on the eastern side in Guangxi Dachang. It has always been regarded as a single granite--porphyry dyke. Through the research, the authors found that for the composition of east rock wall, in addition to granite--porphyry, there are sub--basalt, diorite porphyry and tectonic fracture zone. The east dyke is actually a north--south, multi--phase tectonic--magmatic belt. It is the main ore and rock controlling structure of Dachang tin deposit.
