位于卡尔特塔南南西方向约37km处的哈依威金矿山中金的矿化与发育于寒武—奥陶系温莎山火山岩中的遭受强烈剪切的流纹质熔岩和火山碎屑岩中的富重晶石红土有关。非常细粒的自然金不规则地分散于砂质红土中,这种红土含有不规则块状重晶石和石英,并被褐铣矿和离岭土所胶结。矿床中部见到角砾结构,金含量最高。据推测,金和重晶石原来是在小型海底火山喷口的近地表细脉带中发生沉淀的。附近硅质富铁岩层被认为是海底黄铁矿喷气岩的风化残余。由于后期强烈的褶皱作用,主要地层发生倒转,火山岩系被抬升并暴露于地表而长期遭受剥蚀。在酸性风化条件下,细脉带的含昔铁矿岩石和喷气岩极易被分解,风化剖面中金发生活化而富集。 1979年至1983年,已回收金21.8kg,估计矿石的推测储量为50000t,品位5g/t。哈依威矿山为成功地进行小规模开采和选矿提供了实例。
The mineralization and evolution of the gold from the Hakeiwei gold mine, located about 37 km south-west of the Carthusian, in the strongly sheared rhyolitic lava and volcaniclastic rocks of the Cambrian-Ordovician Windsor volcanic rocks Rich barite laterite-related. The very fine-grained natural gold is irregularly dispersed in sandy laterite, which contains irregular massive barite and quartz and is cemented by brown-milling and off-setting. In the middle of the deposit, breccia structure is seen with the highest gold content. It is speculated that gold and barite were originally precipitated in the near-surface veins of small submarine volcanic vents. Nearby siliceous iron-bearing formations are considered as weathered remnant of submarine pyrite jet rock. Due to the intense folds in the later period, the main strata were inverted and the volcanic rocks were raised and exposed to the earth’s surface for long-term erosion. In acidic weathering conditions, the veins of fine-veined iron ore and pyroxene are easily decomposed and the gold is activated and enriched in weathering sections. From 1979 to 1983, 21.8kg of gold had been recovered. The estimated reserves of ore were estimated to be 50,000t at a grade of 5g / t. Hariwe mine provided examples for successful small-scale mining and beneficiation.
