浅成岩浆体系结晶机理研究

Studies of Crystallization Mechanism of Hypabyssal Magmatic System

随着岩浆体系结晶机理研究的不断深入，火山岩和侵入岩岩浆动力学理论已经进入到模型建立阶段。本文试图通过对安徽沙溪斑岩体进行实例研究，先求出斜长石斑晶的存储时间，再算得晶体成核速率和生长速率。

With the increasing deepening of the study on crystallization mechanism of the magmatic system, the magmatic kinetic theory of volcanic and intrusive rocks has entered the stage of establishing a model. Through the study of the example of Shaxi porphyry body in Anhui Province, the authors first figured out the storage time of plagioclase phenocrysts, then calculated the nucleation rate and growth rate of the crystals and , on such a basis, established the thermal model for cooling of the hypabyssal magmatic system
