美国新墨西哥的芒特泰勒铀矿床赋存于威斯特瓦特峡谷的砂岩中。地下水把凝炭岩中的铀溶带到具有氧化还原环境的砂岩中沉积成矿床。主要矿物为水硅铀矿及沥青铀矿,富含共生炭质物质。有三个主矿床产于“C”砂岩层,一个主矿床产于“D”砂岩层。每个矿床的形态复杂,矿化从呈细脉到厚几米、宽几十米、长几百米的大矿床,矿体厚度最大为10米。总储量1.21亿磅U_3O_8,平均品位0.25％U_3O_8。最小可采厚度2米,边界品位0.10％。
The Mount Taylor uranium deposit in New Mexico, USA, is hosted in sandstone in the West Point Gorge. Groundwater deposits the uranium dissolved in the carbonaceous rocks into sandstones that have a redox environment and deposit into mineralized beds. The main minerals are hydrated silicon uranium ore and uranium ore, rich in symbiotic carbonaceous material. There are three main ore deposits in the “C” sandstone and one main ore deposit in the “D” sandstone. The shape of each deposit is complex. Mineralization ranges from the veinlets to a few meters in thickness, tens of meters in width and several hundred meters in length. The ore body thickness is up to 10 meters. The total reserves of 121 million pounds U_3O_8, the average grade of 0.25% U_3O_8. The minimum recoverable thickness of 2 meters, the border grade of 0.10%.
