笔者通过对龙陵—潞西地区各个花岗岩体矿物内包裹体的研究,获得以下认识: 1.各花岗岩体中各种类型的固相和多相流体包裹体的出现,说明(?)区花岗岩浆经历了高温到低温逐渐冷却的演化过程。 2.发现了熔融玻璃质(结晶质)一流体包裹体。这种特殊类型包裹体的出现,说明原始岩浆是极不均匀的.并富含水等挥发性组份。 3.燕山期的岩浆活动从早期到晚期形成的岩体,它们的成岩温度是逐渐降低的,从1020℃到800—850℃。 4.研究表明该区花岗岩应是重熔岩浆型花岗岩,属壳源成因系列。
Through the study of the inclusions of various granites in Longling-Luxi area, the following findings are obtained: 1. The occurrence of various types of solid and multiphase fluid inclusions in each granite, indicating that the The pulp experienced a gradual cooling from high temperature to low temperature. 2. Found molten glass (crystalline) a fluid inclusions. The advent of this particular type of inclusion indicates that the original magma is extremely heterogeneous and is rich in water and other volatile components. 3. Yanshanian magmatism From early to late formation of rock mass, their diagenetic temperature is gradually decreased from 1020 ℃ to 800-850 ℃. 4. The study shows that granite in this area should be remelted magmatic granulite, belonging to the genesis series of crust.
