东准噶尔地区，不同时期和成因归属的花岗质岩石广为发育，成矿作用十分明显。对其中最具代表性的两类花岗质成矿岩浆建造，即Ａ２型造山后碱性花岗岩和隶属科迪勒拉Ⅰ型花岗岩类的中性—中酸性浅成侵入岩进行研究。前者主要与锡的成矿密切相关，形成自成体系的锡矿床系列。后者主要与铜、金成矿息息相关，形成自成体系铜矿床系列和金矿床系列。二者均具有很好的找矿前景，尤以与中性—中酸性浅成侵入岩类有关的金矿床系列，其找矿前景巨大。 The eastern Junggar region, different periods and genesis of granitic rocks are widely developed, the mineralization is very obvious. Two of the most representative types of granitic mineralization magmatisms, that is, the A2 type orogenic alkaline granite and the Cordillera-type I granites are studied. The former is closely related to the tin mineralization and forms a self-contained tin deposit series. The latter is mainly related to copper and gold mineralization, forming a series of self-formed copper deposits and gold deposits. Both have good prospects for prospecting, especially gold deposits related to neutral-moderately acidic shallow intrusive rocks, with a great potential for prospecting.
