引言赫姆洛矿床是一个产于太古宙变质碎屑岩、火山碎屑岩和火山岩层内的层状中等到局部高品位的Au—Mo矿床,位于安大略省马拉松以东的沿17号公路35公里处(图1,见下一篇文章图1)。矿床地层以具有广泛的角闪岩相片岩和非叶片状花岗变晶变质岩或花岗霏细岩变种为特征。金巨人矿床的主矿带和下矿带作为富Au、Mo、Ba、Sb、Hg、As、V和B的含微斜长石层,赋存在几个不同岩性的岩层中。
INTRODUCTION The Hemlo deposit is a stratiform, intermediate-to-high-grade Au-Mo deposit dating from Archean metamorphic clastic rocks, volcaniclastic rocks and volcanic rock formations along Highway 17 to the east of the Marathon in Ontario Km (Figure 1, see next article Figure 1). The deposit strata are characterized by a broad range of amphibolite and non-leaf granitic metamorphic or granodiorite breccias. The main and lower metallogenic belts of the gold giants deposit are characterized by the presence of slightly plagioclase layers rich in Au, Mo, Ba, Sb, Hg, As, V and B in several rock formations with different lithologies.
