摘要
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。
Granitic rocks of different ages and different origins are extensively developed in east Junggar, meallogenesis which of is quite obvious Two most representative kinds of granitic metallogenetic magmatic formations from them, namely, post-orogenic alkali granite of A 2 -type and intermediate-intermediate acidic hypobyssal intrusive of the cordilleran I-type granite are studied The former is closely and chiefly related to tin mineralization to form a tin deposit; the latter to copper-gold mineralization to form a copper deposit series and a gold deposit series in itself system The two show a obvious exploration prospect Especially, the gigantic exploration prospect of the gold deposit series is related to the intermediate-intermediate acidic hypobyssal intrusive
