我国金矿床(点)分布广泛,具有成群成组出现,分段集中展布,成因不受类型、地质构造和时代限制的特点。据此,将全国金矿床(点)划分为108个集中区。它们的分布受地质构造的严格控制。在不同构造单元内,不同类型的矿床与一定的地层岩石、地质构造和成矿物理化学条件有关;矿化的富集与一定的岩石组合有关;矿化类型尽管多种多样,但均受不同形态的构造类型控制,产于特定的部位。因此,在不同地区、不同地质构造中,常形成不同类型、不同规模的金矿床。一个金矿集中区中,绝大多数具有两种以上的成因类型,这主要是成矿物质来源不同所致。我国有优越的金矿成矿条件和广阔的找矿前景。文中提出了五个类型找矿主攻目标。 The gold deposits (spots) in our country are widely distributed, with the emergence of large groups of groups and the concentrated distribution of sections, which are not affected by the type, geological structure and times. Accordingly, the country’s gold deposits (points) is divided into 108 concentrated areas. Their distribution is closely controlled by the geological structure. Within different tectonic units, different types of ore deposits are related to some stratum rock, geological structure and mineralization physicochemical conditions; mineralization enrichment is related to certain rock assemblages; although mineralization types are diverse, they are all affected by different forms The type of construction control, produced in a specific area. Therefore, in different regions and different geological formations, gold deposits of different types and sizes are often formed. In a gold concentrate area, the overwhelming majority have two or more genetic types, mainly due to the different sources of ore-forming materials. Our country has superior gold mineralization conditions and broad prospects for prospecting. The article proposed five main types of prospecting targets.
