摘要
地质、岩石地球化学及构造变形特征综合研究表明，松树沟超镁铁质岩是底辟侵位于上覆玄武岩中的地幔岩部分熔融残余体，该残余体在底辟上侵的过程中发生塑性变形，并再次部分熔融。其残余物为橄榄质糜棱岩，熔体部分形成中粗粒纯橄岩板状或脉状体及其伴生的铬铁矿。
Combination study of geology geochemistry, petrology and structural deformation on Song shu Gou ultral-mafic rocks shows that the ultra-mafic rocks were the partial melting mantle relics emplaced diapiricaly in the overlying basalt. And Partial melting took place again huring diapiration with medium-coarse dunite slabs and dykes and Cr ore in the melted parts.
