变质细碎屑岩型金矿床在国内外分布广泛，其中部分矿床具有超大型规模。矿床由三个阶段形成：沉积阶段在相对半封闭还原海盆中发育，常夹火山物质及热水沉积且富碳、硫、金的浊流沉积物，构成了金的矿源层；区域变质阶段随温度、压力增高，有机质破坏，粘土矿物消失，金被释出、归并、定向迁移、集中得到初步富集；成矿阶段的构造热液事件使金从变质细碎屑岩中淋出、迁移，或与其他来源的金汇集、沉淀构成矿床。矿床可分活化带型及造山带型，成矿主要为改造作用产物，少数矿床可能有岩浆叠加作用发生。
Metamorphic fine clastic rock gold deposits are widely distributed at home and abroad, some of which have a very large-scale deposits. The deposit is formed by three stages: the depositional stage is developed in the relative semi-closed reduced sea basin, often containing volcanic material and hydrothermal sediment and rich in carbon, sulfur and gold turbidity flow sediments, forming the gold source layer; regional metamorphism stage The temperature and pressure increase, the destruction of organic matter, the disappearance of clay minerals, the release of gold, the mergence and directional migration, and the initial concentration enrichment. The tectono-hydrothermal events in the ore-forming stage allow gold to leach and migrate from the metamorphic fine clastic rocks, Or together with other sources of gold, sedimentary deposits. The ore deposit can be divided into active zone type and orogenic belt type. The metallogenetic alteration is mainly the product of alteration, and a few mineral deposits may have superposition of magma.
