| 中文摘要: |
| 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,与斑岩铜矿主要产于汇聚板块边缘造山作用的成矿地质背景相一致。成因类型为:与斑岩铜矿成矿系统有关的夕卡岩型铜矿床；也可称为“赛什塘型” 斑岩铜矿；具有“三位一体”矿化分布模式；矿床富集规律主要有:断裂构造复合控矿规律,岩体构造与接触带构造复合控矿规律,地层与构造复合控矿规律,岩相控矿规律以及蚀变分带控矿规律。 |
| 英文摘要: |
| The Saishitang metallogenic belt is located in the Hercynian-Indosinian orogenic belt, its metallogenic tectonic environment 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” porphyry copper deposit which is characterized with “Trinity” mineralization distribution pattern. The enrichment regularities of copper orebodies are mainly as followings:complex fracture structure controlling, composite controlling of rock mass structure and contact structure,, composite controlling of strata and structure, and compositing controlling of lithofacies and alteration zoning. |
