| 中文摘要: |
| 文章通过对莲花山银铜矿床与成矿关系较密切的次火山岩的岩石化学、微量元素、稀土元素和同位素分析,对该矿床的成矿地质背景进行了探讨;认为莲花山银铜矿床是在太平洋板块向亚洲大陆板块俯冲下产生的弧后引张区,由来源于上地幔或下地壳的深源钙碱性岩浆多次上侵,在相对封闭的还原环境下形成的中高温热液矿床. |
| 英文摘要: |
| Based on analyses of petrochemistry, rare elements, rare earth elements and isotope elements, geology background of Lianhuashan Ag-Cu deposit is discussed. The deposit is located in a stretch region of back arc produced by subduction of Pacific Ocean plate to Asia plate. It is considered that Lianbuashan Ag - Cu deposit is a middle - high temperature hydrothermal deposit formed in a relative close and reduction environment, and by repoated calc- alkaline intrusive coming from upper mantle and lower crust. |
