中文摘要: |
独石口沸石矿位于沽源晚侏罗世火山—沉积盆地南缘,赋矿地层主要为张家口组上亚组凝灰岩。矿床沉积古环境为小型陆相淡水盆地,盆地发育受燕山期岩浆岩侵入影响,在一系列同沉积断裂构造控制下形成。含矿层形成至今,矿区始终处于相对下降趋势。矿石矿物组分单一,主要为斜发沸石,矿化均匀,品位稳定,沉积环境稳定持久,矿床类型为内陆淡水湖火山碎屑沉积型矿床。同时代火山—沉积盆地成矿潜力巨大。 |
英文摘要: |
The Dushankou zeolite deposit is located in the southern margin of the Late Jurassic volcanic-sedimentary basin in Guyuan, and the ore-bearing strata are mainly the upper subgroup tuff of the Zhangjiakou Formation. The sedimentary paleo environment of the zeolite deposit is a small-scale continental freshwater basin; its development is affected by the Yanshanian magmatic rock intrusion and is formed under the control of a series of synsedimentary fault structures. The mining area has been in a relatively downward trend since the formation of the deposit. The ore mineral composition is simple, mainly clinoptilolite. The deposit has even mineralization and stable grade, indicating a stable and long-lasting sedimentary environment. The deposit type is a volcano- clastic sedimentary deposit in inland freshwater. The zeolite deposits formed in contemporaneous with volcano-sedimentary basins indicates that the mineralization has a great potential. |
