| 中文摘要: |
| 文章以大别山北麓罗山地区中生代火山岩盆地为研究区对象，在分析盆地火山岩特征及含铀性的基础上，结合现代火山岩型铀成矿理论，认为罗山中生代火山岩盆地具有较好的铀成矿潜力。同时，探讨了罗山冯楼地区铀矿成因，建立了"两层楼"铀成矿模式，并预测本区的主要找矿位置为火山机构内部、盆地基底不整合面上下与切盆断裂交切带内，次要的找矿位置为火山岩盆地内的氧化还原界面附近。 |
| 英文摘要: |
| This paper deals with Mesozoic volcanic basin in the north side of Dabie Mountain. Based on characteristics of the volcanics and its uranium ore-bearing property and the modern uranium metallogenic theory, the Mesozoic volcanic basin in Luoshan county is potential for prospecting volcanic basin type uranium deposit. Genesis of Fenglou uranium deposit in the basin is discussed and 2-layer ore-forming model is built. Targets are mainly predicted at interior of volcanic edifice, above and bellow the unconformity face of the basin basement and in the interior of the zones where faults cut the basin, then near the oxidation reduction interface in the basin. |
