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 magmat.
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
Gold deposits related to intermediate acid hypabyssal rocks were recently discovered in eastern margin of Juggar Basin in Xinjiang.
与中酸性浅成岩有关的金矿是新疆东准噶尔地区新发现的一个重要金矿类型 ,通过解剖有关中酸性小岩体及其典型矿床 ,初步探讨了此类金矿的基本成矿特征 ,认为该矿化类型总体上受控于一套华力西中晚期的中酸性浅成小杂岩体 ,并指出了其找矿方向。
