近年来,在江南古岛弧东侧,绍兴—江山深断裂中,陆续发现并勘探了一批金矿床。这类矿床埋藏浅,品位较高,易采易选,经济效益好,而且其地质背景、矿床特征、物质来源和成矿作用等方面,都有其独特之处,故可成为独立的金矿类型——幔源岩浆热液金矿。我国幅员辽阔,板块碰撞带和深断裂均较发育,寻找幔源岩浆热液金矿具有广阔的前景。本文着重讨论这类矿床的成矿特征和成因。
In recent years, a number of gold deposits have been discovered and explored one after another in the Shaoxing-Jiangshan deep fault to the east of the Jiangnan ancient island arc. Such deposits are shallow buried, high grade, easy to adopt and easy to choose, with good economic benefits, and have unique features in terms of their geological background, deposit characteristics, material sources and mineralization, and thus can become independent gold mines Type - mantle-derived magmatic hydrothermal gold deposit. Our country has a vast territory, plate collision zone and deep fault are more developed, looking for mantle-derived magmatic hydrothermal gold has broad prospects. This article focuses on the mineralization characteristics and genesis of these deposits.
