| 中文摘要: |
| 内蒙古乌兰察布市卓资县哈达图大地构造位置处于华北地台北缘内蒙台隆内,三级构造单元为凉城断隆,石英质玉石矿床与中生代早白垩世白女羊盘期火山构造活动关系密切。矿体赋存于早白垩世火山构造角砾岩中,系火山热液在火山构造裂隙充填成矿,多呈不规则脉状,多期岩浆热液形成的石英质玉石。其主要成分均为硅质,而透明度差异较大,半透明—微透明。据现有资料,早期石英质玉石多数透明度稍低,铁质 、杂质较高,颜色往往较深,多为碧玉、玉髓混合体。而晚期石英质玉石质纯透明。矿区西毗邻四大名山,该区石英质玉石找矿前景广阔,市场需求的快速增长为玉石产业的发展提供了新契机,发展潜力巨大。 |
| 英文摘要: |
| The area is located in Hadatu, Zhuozi county, Ulanchabu city, Mongolia, its geotectonic location is in the northern margin of the North China’s ground uplift and in the inner Mongolia geological uplift, the tertiary tectonic unit is Liangcheng fault uplift, the quartz jade deposit is closely related to the volcanic tectonic activity of the Mesozoic Cretaceous White Female Period, the ore bodies occur in breccias of volcanic structural of the early Cretaceous, which filled into volcanic tectonic fissures with volcanic hydrothermal fluid, mostly in irregular veins, the main components of quartz jades formed by multi-stage magmatic hydrothermal fluid are all siliceous, their transparency is quite different, translucent- micro translucent. According to the existing data, most quartz jades in early have lower transparency, higher iron and impurities, and darker colors, mostly mixed with jasper and chalcedony (The first geological team of Hebei Geology & Mineral Resources Bureau, 2015). The quartz jades in later are pure and transparent. The prospecting potential of the quartz jades deposit which is adjacent to the four famous mountains in the west of the mining area is huge, the rapid growth of market demand provides a new opportunity for the development of the jade industry and broad prospecting prospects. |
