在德兰士东部萨比—朝圣者之家金矿区元古界德兰士系的沉积地层内,产出有当地称之为“礁”的层状石英—硫化物—金矿脉,它们同澳大利亚西部的特尔福金矿具有许多相同的特征,从这些矿床中已开采黄金约180t。对埃兰兹霍格特矿详细研究后发现,金有两个沉积作用阶段,这两个阶段都与沉积地层内平行层面的冲断作用有关,变形只产生在强干岩层中的非强干页岩夹层内。大部分金是在矿化的第二阶段带入的,并赋存在早期形成的硫化物矿物的裂隙中,与早期硫化物伴生的强干石英脉的沉积和金的矿化作用,导致“礁”带中变形类型由早期页岩中的剪切作用改变为晚期石英—礁中的复合断层作用,推测金是由伴随断层作用的流体携带运移的,并且成矿来源为岩浆源。
In the Sedimentary strata of the Proterozoic Drains in the Sabi-Pilgrim’s goldfield in eastern Derwent, stratiform quartz-sulphide-gold veins, locally known as “reefs,” are produced, They share many of the same characteristics as the Delphi gold mine in Western Australia, where approximately 180 tons of gold have been mined. A detailed study of the Elandszoggart mine found that gold has two depositional stages, both of which are related to the thrusting of the parallel planes within the sedimentary formation, which deformation is only produced in the non-over-drilled Shale interlayer. Most of the gold was brought in during the second stage of mineralization and was deposited in the fissures of earlier formed sulfide minerals. The deposition of strong dry quartz veins associated with early sulfides and the mineralization of gold led to the “ The type of deformation in the ”Reef" belt changed from the shearing action in the early shale to the composite fault in the late quartz-reef. It is presumed that gold migrated by the fluid accompanying the fault and the ore-forming source was magmatic source.
