摘　　要：根据矿石建造分析原理和秦岭造山带泥盆纪热水沉积盆地特征，将秦岭造山带多金属热水沉积矿石建造划分为秦岭微板块陆缘复合盆地金或金多金属矿石建造和秦岭微板块内裂陷－ 坳陷盆地铅锌金多金属矿石建造，并据各二级矿石建造内部的特点划分出次级矿石建造。从秦岭造山带大地构造演化角度论述了矿石建造形成的地质背景和各矿石建造之间的关系。According to the principle of formation analysis and characteristics of Devonian thermal sedimentary basin, the thermal sedimentary ore formation of Qinling orogenic belt is divided into Au polymetallic ore formation on the continental margin of Qinling microplate and the Pb-Zn-Au polymetallic ore formation within the rifting basin in Qinling microplate. Accoding to the character of second-order ore formation, they are subdivided into the third-order ore formation. Based on the tectonic evolution of Qinling orogenic belt, the tectonic settings and the relations among the ore formations, and the control of contemporaneous fault on ore deposits are briefed.
