The gold mineralizations of China have a wide distribution over the country and a variety of types. A majority of them are of medium to small size. Metallogenetic features of several main types gold deposits and their economical significance in industrial utilizations are summarized in this paper. Their types are: quartz vein type, fractured-altered rock type. porphyry type, volcanic rock type, carbonate type, placer and accompanying gold. From a view point of industrial utilization, of the annual output of gold for the whole country, 75% are came from gold -bearing rocks, 10% from placer and 15% from accompanying gold in other deposits. With regard to the prospect and guideline for gold exploration in future, the author hold that it is necessary to proceeding from actual conditions lay particular emphasis on the exploration of the most prospective gold deposits, the fractured altered rock type and quartz vein type (composite vein). Furthermore. measures should be adopted to work out a long term plan and to strengthen investigation in order to make a break through in search for world-large gold deposits in our country.

我国金矿资源的特点是:分布广、类型杂、中小型矿床居多数。文中概述和列举了我国金矿几个主要类型的成矿特征及其在工业利用上的经济意义。这些类型是:石英脉型、破碎蚀变岩型、斑岩型、火山岩型、碳酸盐型、砂金型和伴生金。从工业利用上看,全国黄金年产量的75%采自岩金,砂金占10%,伴生金占15%。就我国今后找金矿的前景和地质工作部署问题,作者提出:要从现实出发,续继侧重扩大最有潜在远景的破碎蚀变岩型和石英大脉(复脉、脉带群)型金矿床。从长远考虑,要进一步采取措施,加强科研工作,制定规划,有目标地探索世界型的金矿床在我国突破的可行性和现实性。

Tectonically, the Liaoning Province is situated in the northern part of the North China Platform. It makes up the eastern end of a gold-polymetal metallo-genie belt that constitutes part of the Pacific metallogenic belt.The gold deposits in the Liaoning Province are classified into four types in this paper: a) the Mesozoic volcanic-bubvolcanic hydrothermal type; b) the Me-sozoic altered and fractured quartz lodes; c) the Mesozoic Maoling altered rock type and d)the Archean Longwangmiao greenstone type....

Tectonically, the Liaoning Province is situated in the northern part of the North China Platform. It makes up the eastern end of a gold-polymetal metallo-genie belt that constitutes part of the Pacific metallogenic belt.The gold deposits in the Liaoning Province are classified into four types in this paper: a) the Mesozoic volcanic-bubvolcanic hydrothermal type; b) the Me-sozoic altered and fractured quartz lodes; c) the Mesozoic Maoling altered rock type and d)the Archean Longwangmiao greenstone type. The above four types of gold deposits are concentrated in ten auriferous provinces in the Liaoning Province. These auriferous provinces are strictly controlled by the long active EW trending basement structures, the regional NW-SE trending compressive structures and the Mesozoic NE to NNE trending structural-magmatic zones. The auriferous provinces are usually located at the intersections of these structures. These auriferous provinces comprise two "U" shaped patterns in the western and southern Liaoning Province respectively, somewhat similar to two conjugate images. The"U" pattern in the southern Liaoning Province was controlled by the contact line between the eugeosyncline and miogeosyncline of the Early Proterozoic aulacogen-the so-called"M-Z"line, e.g., it is controlled by the basement structural active zone) whereas the "U" pattern in the western Liaoning Province was controlled by the marginal fractures of the Mesozoic volcanic basin,The famous Tanlu Fracture zone serves as the axis of the two conjugate "U"patterns.Deep geophysical data suggest that the tectonic style of the Liaoning Province had been closely related to the formation-accreation-remobization events of the Sino-Korean platform. Most of the gold lodes in the region are located adjacent to deep fractures(depths greater than 5 km).

本文将辽宁省金矿划分四种类型,十个主要金矿集中区。这些集中区均受华北地台东西向基底构造活动带及中生代太平洋板块俯冲影响、所产生的北西向构造挤压带和北东向构造—岩浆岩带的复合作用控制。它们分别处于太不洋成矿带的内带(辽东)和外带(辽西)。并以郯庐断裂为轴线,构成了两大“U”字形,类似共轭曲线展布的构造样式。根据深部地球物理资料,综合分析了控制金矿集中区构造样式的形成机制。区内脉状金矿大都分布在深断裂(深度大于五公里断裂)带附近。

广西金矿可分为含金石英脉型;含金破碎带蚀变岩型;微细浸染型;次火山岩型和含金方解石脉型等七种。近几年的找矿突破,己使微细浸染型金矿的保有储量取代含金石英脉型金矿而跃居前茅,其与破碎带蚀变岩型金矿应为广西近期找金的主攻方向。而所圈定的五个成矿区又都各自存在不同的找金远景类型,找矿布署上应予区别对待。
