本文概述了霍姆斯塔克金矿的地质背景、矿床地质,其褶皱构造与变质作用和成矿作用特点。对霍姆斯塔克矿床成因作了简介:该矿为前寒武纪变质的沉积同生层控及层状矿床,含矿建造产于20—25亿年前的浅海沉积环境,代表了化学沉淀的富铁碳酸盐—硅酸盐沉积物。矿体主要形成于同生沉积,前寒武纪的区域变质作用和褶皱作用形成了现今的富矿体和矿体产出的格局。
This article provides an overview of the Holmstake Gold Geological Background, the geology of the deposit, its fold structure, metamorphism and mineralization. The origin of the Holmestak deposit was briefly described. The deposit is a Precambrian metamorphic sedimentary stratigraphic deposit and stratiform deposit. The ore-bearing construction was deposited in a shallow-sea sedimentary environment of 20-25 billion years ago and represented the chemical Precipitated iron-rich carbonate-silicate deposits. The ore body is mainly formed in syngenetic sediments. The Precambrian regional metamorphism and folds formed the pattern of present-day rich ore bodies and ore bodies.
