摘要
郝泉沟大地构造位置处于北祁连加里东褶皱带东段中部火山岩带上。矿石呈现出自形-半自形-他形的结构,其构造形态不仅包括脉状-网状,同时松散块状结构也是其主要形态之一。对于矿石而言,含量最好的矿物为铁矿,矿石金成色可高达860%左右。
Haoquangou geotectonically locates in the central volcanic rock belt of the East Caledonian fold belt in North Qilian.The ore has a self-shaped,semi-self-shaped and other-shaped structure,which includes not only vein-network structure,but also loose block structure.For Ore,its content of the best minerals for iron ore,its gold fineness can be as high as 860%.
