该矽卡岩型铜金矿床位于阿尔泰萨拉寇克申花岗杂岩体与下寡武统火山沉积岩之接触带上,热液型金矿化(360─130℃)多叠加于早期矽卡岩(>400℃)之上。金矿化多分布于石榴万一硅灰石矽卡岩中。在氧化作用过程中导致次生成化物富集、自然金的成色降低,原因是金的活动性比银更强。与之同时,在氧化作用过程中自然金有部分银去除,故其成色与内生矿石中自然金相近。因此,在氧化带中自然金的成色具有广阔的离散性特点。为此,在评价深部矿石过程中应充分地加以考虑。
The skarn copper-gold deposit is located on the contact zone between the Alta Sara Koksong granite complex and the inferior volcanic sedimentary rocks. The hydrothermal gold mineralization (360 130 ℃) is superimposed on the early skarn (> 400 ° C). Gold mineralization and more distributed in pomegranate wollastonite skarn. In the oxidation process leads to the formation of secondary compounds enrichment, natural gold to reduce the quality, because the activity of gold is stronger than silver. At the same time, the natural gold has some silver removed during the oxidation process, so its quality is similar to the natural gold in the endogenous ores. Therefore, the nature of gold in the oxidation zone has a wide range of discrete nature. For this reason, it should be fully considered in the evaluation of deep ores.
