梅杰斯克里克(Majors Creek)金矿的矿脉主要由石英、碳酸盐脉石以及金、金—银碲化物和贱金属硫化物组成,存在于硅化和绢云母化的岩墙或布雷德伍德岩体(Braidwood Granite)的花岗闪长岩中。流体包裹体的研究表明,沉淀作用发生在350℃—80℃范围内的低盐度矿液中。具经济意义的Au-Ag碲化物大约在155℃时发生沉淀。矿物沉淀作用是由于液相CO_2从原生富CO_2的水流体中析出所致。所见到的泥化蚀变是沸腾带之上酸性淋滤作用的产物。矿化作用具有浅成低温热液矿化的特征,可能是在热液循环期间形成的。推测梅杰斯克里克金矿和邻近的伊登—亚尔威尔断裂(Eden-Yalwal Rift)带中类似的浅成低温热液金矿床具有成因关系。
The veins of the Majors Creek gold mine are mainly composed of quartz, carbonate gangues, and gold, gold-silver tellurides and base metal sulfides, present in silicified and sericitized dikes or in brad In the granodiorite of the Braidwood Granite. Fluid inclusions studies have shown that the precipitation occurs in low salinity ore fluids in the 350 ° C-80 ° C range. Au-Ag tellurides of economic importance precipitate at about 155 ° C. The sedimentation of minerals is due to the precipitation of liquid phase CO 2 from the primary CO 2 -rich aqueous fluid. The muddy alteration seen is the product of acid leaching over the boiling zone. Mineralization has the characteristics of epithermal mineralization, probably formed during the hydrothermal cycle. It is speculated that there is a genetic relationship between the similar megacytremal hydrothermal gold deposits in the Mejeskerke gold deposit and the adjacent Eden-Yalwal Rift belt.
