混合岩建造的大地构造类型及其对比

混合岩建造按其形成的不大同大地构造环境，可划分为2个大地构造类型：地洼型混合岩建筑和地台型混合岩建造。地洼型混俩岩建筑具有独特的大地构造属性，明显不同于地槽型混合岩建造，这主要表现在：（1）产出于后地台块断造山带的大地构造环境，限于规模较大的线性断裂带之内；（2）具有独特的由变质岩－混合岩－花岗岩呈三位一体的组合建造系列，在混合岩中存在高温低压相系的矿物组合。

The tectonic types of migmatite formation and their contrast

The migmatite formations are devided into the geosyncline type migmatite formation and the Diwa type migmatite formation from the tectonic setting.The Diwa type migmatite formation posesses an independent tectonic property. It is obviously different in the two aspects from the geosyncline type migmatite formatin. (1)It was formed in the tectonic setting of the Diwa block-faulting orogenic belt after platform, and restricted to the big linear fault zone. (2)There is a distinctive association formation series that was three in one formed by the metamorphic rock, the migmatite and the granite, and there is a mineral association of the facies series of the high temperature and the low pressure in the migmatite.
