摘　　要：深变质岩区通常指遭受到麻粒岩相和高角闪岩相变质作用的变质地区。工作区为巴彦乌拉山深变质岩区,在高级变质区研究中,深熔作用则指那些在与高级变质作用相联系的区域地质事件演化过程中,处于地壳中、深部的变质岩,由于温度升高、压力降低、流体加入或者构造作用发生,导致其部分乃至全部熔融的地质作用和过程。内蒙古巴彦乌拉山地区位于华北陆台北缘西段。这一地区为深变质岩区,区内地层主要以中太古届下阿拉善群为主体。区内主要发生的变质作用是区域变质作用,出露麻粒岩相、角闪岩相、片麻岩相、绿片岩相、以及混合岩,其中包括大范围出露的表壳岩及深熔片麻岩,深熔混合岩。Hypometamorphic rock area usually subjected to metamorphism of granulite facies and areas of high amphibolite facies metamorphism. The work area is the deep metamorphosed rock area of Bayanwula mountain, in the studing, Anatexis re-fers to those evolution in regional geological events associated with high-grade metamorphism in the process, in the crust or the deep metamorphic rocks, due to the high temperature, pres-sure drop, fluid into or tectonics occurred, causing geological effects of the part or all of the melting and process. Bayanwula mountain of Inner Mongolia area is located in the western section of the north margin of North China Platform. In the deep meta-morphosed area, the mainly stratums exposed is Ar2 w. Regional metamorphism is mainly occurred within the area, including granulite, amphibolite facies, gneiss, greenschist facies, and mixed rock, belongs to the supracrustal rocks and plutonic body.
