摘　　要：小尖山金矿是韧性剪切带型金矿,它受韧性剪切带控制,并以剪切作用为主要成矿机制。它受多级剪切带控制并产于次级剪切带中。金质为多来源,发育于变质岩区。剪切造成的物理化学梯度及构造化学在成矿过程中起主导作用。Xiaojianshan deposit is a ductile shear zone type Au deposit. Shearing is the main ore-forming mechanism. The deposit is controlled by multilevel shear zone and occurs in sub-shear zone. Gold is from many sources.
