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

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，进而建立起浅成岩浆体系冷却的热模型。
