麦克莱思矿化呈狭长扁透镜矿体(平均品位1.8％U_3O_8)产于阿萨巴斯卡砂岩系与下伏的太古界/下元古界阿菲布群基底之间的不整合面上。~(40)Ar/~(39)Ar激光探针和K/Ar常规分析资料是根据采自下列环境的伊利石测定的:①高品位U(-Ni-Co)矿化周围的蚀变晕圈;②砂岩系内部重结晶的沉积岩层;③砂岩中石英颗粒间的填隙物和④风化层。蚀变晕圈中的伊利石得到年龄值为1321±44和1002±33Ma(n=20),这与该区其他铀矿床已
The mineralization of McClelze’s elongated, flat lens ore (average grade 1.8% U_3O_8) was produced on the unconformity between the Athabasca sandstone and the underlying Archean / Lower Proterozoic Affymetrix basement . The ~ (40) Ar / ~ (39) Ar laser probe and K / Ar routine analysis data were based on illites collected from the following environments: ① Erosional halo around high mineralization of U (-Ni-Co) Circle; ② reclaimed sedimentary rock within the sandstone system; ③ interstitial sandstone quartz particles and ④ weathering layer. The illite in the altered halo is obtained at ages of 1321 ± 44 and 1002 ± 33Ma (n = 20), which is consistent with the other uranium deposits in the area
