摘　　要：玲珑—焦家地区金矿受长期活动的郯庐左旋平移剪切带及中生代地幔热隆伸展构造的双重控制 ,两种相互独立的动力学体系叠加后构成举世罕见的正滑 -走滑复合型成矿构造体制 .石英脉型与蚀变岩型金矿分别形成于早期 (韧性至脆韧性域 )的左旋走滑 -正滑成矿构造体制与晚期 (脆性域 )的正滑 -左旋走滑成矿构造体制 ,两类金矿体的雁列型式。The gold deposits in Linglong-Jiaojia district are controlled by both the Tanlu shear zone, which is long-term active and characterized by left-lateral strike, and the extensional tectonics caused by mantle uplift in Mesozoic ear. The superimposition of two kinds of independent dynamic systems formed a rare metallotectonic regine which is the compound type of normal-slip and strike-slip. The gold-bearing quartz type and alteration type were formed in the early (ductile and brittle-ductile domain) left-lateral strike-slip_normal slip metallotectonic regine and later (brittle domain) normal slip_left-lateral strike slip metallotectonic rigine respectively, and their en-echelon type ,dip and dip-angle, pitch and pitch-angle are confined by the condiction of dynamics under the different tectonic rigine. Therefore, new realizations on Jiaojia fracture, Potouqing fracture and Linglong fracture are formed.
