| 中文摘要: |
| 大草坪钼矿位于冀北上黄旗构造岩浆岩带钼多金属成矿带中,赋矿围岩为花岗岩及花岗闪长岩,成矿时代为燕山期,成矿作用受燕山造山带的控制。研究表明,其成矿物质来源具多源性、多成因、多期次叠加的特征。包裹体液相成分分析显示成矿热液以大气降水为主,包裹体均一化温度为100~360℃,主要在180~220℃范围内;Si,S同位素数据显示成矿流体来源于深部,并与侵入岩体同源,说明大草坪钼矿床属与燕山期岩浆作用有关的中低温热液矿床。 |
| 英文摘要: |
| Dacaoping molybdenum deposit is located in Mo-poly-metal metallogenic belt at Shanghuangqi tectonic-magmatic belt in northern Hebei Province,hosted by granite and granodiorite and formed in Yanshanian period.The metallogeny is controlled by Yanshan orogenic belt.It is characterized by multi-sources,multi-genesis and multi-ore-forming-stage.Ore fluid is mainly meteoric water.Homogenization temperature data of fluid inclusions in range of 100 to 360℃ and concentration between 180 to 220 ℃ indicate that Dacaoping Mo deposit is a meso-epithermal deposit. |
