| 摘 要： | 大平掌矿床由上部层状块状硫化物矿体和下部细脉浸染状矿体组成，双层结构清楚。块状矿体中发育典型的草莓状和鲕状硫化物。成矿地质背景和矿石中的金属元素及REE配分形式、S同位素组成、流体包裹体特征等均与黑矿型矿床及现代海底热液活动区硫化物矿床相似。矿床典型的火山喷流沉积成因。

| Abstract: | There was a typical "two-layer structure" in Dapingzhang Cu-polymetal deposit, which was composed of the upper massive sulfide orebody and lower veinlet-disseminated sulfide orebody. Sulfides with framboidal and oolitic texture have been found from massive sulfide ore. The deposit is similar in geological setting, distribution patterns of metal elements and REE, sulfur isotopic composition, and fluid inclusion characteristics to the Kuroko-type deposit and modern sulfide deposits in some sea-floor hydrothermal activity regions. Based on the above evidences, it is suggested that metallogenesis was related to volcanic-exhalative-sedimentation. |
