华北地块北缘金矿床类型及成矿系列

华北地块北缘是我国金矿的主要产地之一。其金的成矿地质背景复杂，主要可分为变质基底区、地槽区、盖层区、中生代火山断陷盆地、构造－岩浆活动带５种类型。该区大部分金矿床与中生代构造岩浆活动有关。以成矿作用为主要依据将华北地块北缘金矿床划分为三大类：一类是侵入岩浆热液型金矿床；一类是火山－热液型金矿床；第三类是沉积－改造型金矿床。结合成矿地质背景分析和矿床类型的划分，将华北地块北缘金矿床划分为三个系列组合，即侵入岩浆热液金成矿系列组合、火山－次火山热液金成矿系列组合及沉积－改造金成矿系列组合。

THE GOLD DEPOSIT TYPES AND METALLOGENETIC SERIES ON THE NORTHERN BORDERLAND OF NORTH CHINA MASSIF

The northern borderland of North China massif is one of important metallogenetic provinces of gold in China. There are 5 kinds of geological settings: metamorphic basement area, geosyncline area, cover area, Mesozoic volcanic fault basin and tectonic magmatic active belts. Most of the gold deposits are related with Mesozoic tectonics and magmatic activities. Based on their metallogenesis, the gold deposits are divided into 3 types and 7 subtypes, in which 3 types are intrusive magma hydrothermal , volcanic hydrothermal , and sedimentary remaked type.In light of analysis on the metallogenetic geological settings and subdivision of the ore deposit types, the metallogenetic series of the gold deposits on the northern borderland of North China massif can be divided into 3 series associations:intrusive magma hydrothermal, volcano subvolcano hydrothermal and sedimentary remaked gold ore forming series associations.
