Basing on detailed field survey and laboratory researches on lithological features, mineralogical composition, geochemical and zircon SHRIMP U-Pb data, together with the mineralogical study of chromitite and mantle peridotite heavy mineral bulk sample, various proceedings and recognitions have been achieved:(1) The mantle peridotite is the remnants of partial melted MOR mantle altered by SSZ fluids.
通过详细的野外调查和室内岩石薄片的岩相学、矿物成分、岩石地球化学和锆石SHRIMP U-Pb同位素年代学,铬铁矿和地幔橄榄岩的人工重砂大样的矿物学研究,取得以下进展和认识:(1)认为康金拉地幔橄榄岩为部分熔融MOR地幔残余,叠加了SSZ流体的改造。

According to the geochemical data, the formation of mantle peridotite might be: during the spreading of ocean floor, the MOR mantle underwent variable degrees of partial melting and formed the depleted mantle peridotite with podiform chromitite; during the spreading of ocean basin, intra-ocean subduction happened, REE and LILE rich fluids containing water derived from the subduction slab migrated upwards and metasomatism happened to peridotite relic.
康金拉矿区的地幔橄榄岩的地球化学特征反映了其形成过程的复杂性,表现为:洋底扩张期间,扩张脊下的MOR型地幔的经历了不同程度的部分熔融,形成了亏损地幔橄榄岩,该地幔橄榄岩中赋存了来自深部的豆荚状铬铁矿。

The deep origin of Kangjinla podiform chromitite is suggested by: that for the Kangjinla chromitite and the mantle peridotite rocks, the compositions of the chrome spinel, olivine and clinopyroxene are rather different, which indicates that the chrome spinel in the chromitite is neither the simple concentration of that in the host rocks nor with certain genic relation with mantle peridotite. Though the chromitite might be exotic for host rocks, both of them were carried from deep mantle to the shallow place by mantle plum.
康金拉铬铁矿石与矿体围岩地幔橄榄岩的铬尖晶石、橄榄石和单斜辉石等成分方面明显不同,认为矿石铬尖晶石并非是由副矿物铬尖晶石富集而成,与地幔橄榄岩也不存在成因联系,认为豆荚状铬铁矿床对于近矿围岩地幔橄榄岩而言为外来体,但两者可能均是由地幔深部被地幔柱带到上部。
