摘　　要：赛什塘成矿带位于印支—海西造山带,成矿构造环境属于活动大陆边缘带,与主要产于汇聚板块边缘的斑岩铜矿的成矿地质背景相一致。成因类型为与斑岩成矿系统有关的夕卡岩型铜矿床,也可称为"赛什塘式"铜矿。矿体的形成主要受断裂构造、岩体构造与接触带构造、地层与构造、岩相等控制。The Saishitang metallogenic belt is located in the Hercynian - Indosinian orogenic belt, its metallogenic tectonic envi- ronment belongs to the active continental margin which is consistent with the metallogenic geological background where the porphyry copper deposits are mainly formed by the orogenic process within the convergent plate edge. The genetic type of the deposit is the skarn type copper deposit related to the metallogenic system of the porphyry type copper deposit. Therefore, it is named as ＂ Saishitang type＂. The formation of copper orebodies are mainly as followings： fracture structure, rock mass structure and contact structure, strata and structure, lithofacies and so on.
