摘　　要：安家营子金矿田位于大兴安岭—太行山中生代巨型构造岩浆带中段。金矿床赋存于燕山期二长花岗岩小侵入体中，矿床标型地质地球化学特征可以与绿岩金矿及浅成低温热液金矿对比，具有某些过渡性特征。矿床类型属中温（３００℃）偏高、中深（１６～２．５ｋｍ）成下地壳重熔岩浆热液金矿床，亦可以称之为斑岩型金矿床，其资源潜力巨大。AnJiaYingZi gold minerogenetic field is situated at the midsection of DaxinganlingTaihangshan great Mesozoic tectonicmagmatic zone.The gold ore deposits are hosted in a small intrusion of Yanshanian monzogranite.The typomorphic geologicalgeochemical features of gold deposits can be comparsed with both greenstone formation gold deposits and epithermal gold deposits,showing some intermediate characters.The type of gold deposits belong to middletemperature (slightly higher than 300℃) medium depth(1.6～2.5km) hydrothermal deposit which is derived from remelting lower crust rocks.They can be called porphyrytype gold deposit and has great resources potentialities.
