摘　　要：白云金矿床产于古元古代辽河群沉积-变质岩系,矿化类型为蚀变岩型。研究表明古元古代含金建造、印支晚期-燕山早期岩浆岩系统和韧-脆性断裂系统与成矿有密切时空及物质联系,是金矿化的主控因素;矿化类型受构造应力场和断裂力学性质控制。The Baiyun gold deposit occurred in Gaixian Formation--Dashiqiao Formation（Pt1 ）, the mineralization type is the altered--rock type. This study reveals that the Paleoproterozoic gold--bearing forma- tions, a Late Indosinian-- Early Yanshanian granitic magma system and ductile--brittle fault system close- ly associated with the minerlization in terms of space, time and materials, accounts for the gold minerliza- ion. The minerlization types are controlled both by the tectonic stress field and by the fracture mechanic property.
