浅成脉状金矿是指在近地在至1.5km深度,以充填方式形成,总体形状呈脉状金矿床。其赋矿围岩是多种多样的,以火山岩、次火山岩、浅侵入体最为常见,此外还有变质岩等。热液矿床的形成深度对矿体形状、产状、规模、物质组成和结构构造有重要影响。浅成脉状金矿是我国仅次于中深脉状金矿的第二个重要类型。介绍了浅成脉状金矿的地质特征及进一步分类的方案。
The shallow-veined gold deposit is formed in a filling manner at a depth of 1.5 km in the near-field and has a veined gold deposit in its overall shape. The ore-hosting rocks are diverse, with volcanic rocks, sub-volcanic rocks, shallow intrusions the most common, in addition to metamorphic rocks. The depth of hydrothermal deposit formation has an important impact on ore body shape, shape, scale, material composition and structure. Shallow-vein gold deposits are the second most important type in China after the deep-veined gold deposits. The geological characteristics and further classification schemes of shallow-veined gold deposit are introduced.
