摘要
通过对新疆阿尔泰山南缘原划为侵入的花岗岩基进行深入的,从宏观到微观的观察、研究后认为应属于 S 型花岗岩.根据岩石包裹体测试结果,求得成岩压力大于101×10~8 pa,温度大于416℃.结合地质特征,属于沿区域上大的复式背斜轴部分布的重熔型半原地混合花岗岩.
Based on macroscopic and microscopic research analysis of the fluid inclusions and Study of the geological charactristics the authors are under the impression that the granitic batholiths in Southern Altay Mountains Xinjiang Autonomous Region are S—type granites They belong to semi-autochthonous remelting migmatitic granites whice extend along the axis of laegr regional anticlinorium The diagenetic perssure is above 1.1kb and the temperature is above 416℃.
