| 中文摘要: |
| 位于雅鲁藏布江蛇绿岩带东段的罗布莎豆荚状铬铁矿,产于构造含矿杂岩带中,受幔型韧性剪切带、透镜网络系统和脆性断裂系统的控制,经历了从地幔到地壳、从伸展到挤压、从形成到形变、从改造成矿到矿床改造的成矿演化过程,可划分为重熔贯入型、韧性剪切型、熔离渗滤型、结晶分异型等四种成因类型,是在岩石圈伸展背景下形成的地幔动力矿床。 |
| 英文摘要: |
| The Luobusha podiform chromite deposits, located at the east secton of Yarlu Zangbu River ophiolite belt, existed in ore-bearing structure complex zone, controlled by mantle ductile shear zone, lens network system and brittle fault system, underwent the metallogenic evolution from mantle to crust, from extension to compression, from formation to deformation, from reworking metallogenesis to reforming of chromite deposits, can be divided into four kinds of genetic types including remelting injection type,ductile shear type, melting infiltration and crystallographic differentiation type. They are mantle dynamic deposits formed in the tectonic setting of Mosozoic lithosphere extension. |
