在亚利桑那州中部太古界阿帕契统的德里平温泉石英岩中发现了层控铀矿床。主岩是该统上部层位,一种在近海-潮间环境下沉积在盐湖的富钾的碳质粉砂岩。太古界辉绿岩岩床侵入于岩层中并靠近铀矿床。最初粉砂岩来源于火山碎屑,由于成岩作用和与辉绿岩侵入有关的接触变质作用而强烈蚀变。通常,铀成层间浸染状产于细粒层和含大量纹理和缝合线的层中以及呈细脉状平行或穿切层理。已鉴定有晶质铀矿和铀石。铀产地是在成岩-沉积作用时富集的,由于接触变质作用和绿泥石的蚀变作用而变化。成岩作用使铀从火山沉积物中析出并迁移至还 Stratigraphic-controlled uranium deposits were found in the Apollo-type Drifin thermal quartzite in the Archean community of central Arizona. The host rock is the upper strata of the system, a potassium-rich carbonaceous siltstone deposited in salt lakes in an offshore-tidal environment. Archean diabase greenstone intrudes into the rock formation and is close to the uranium deposit. Originally, the siltstone was derived from volcanic debris and was strongly altered by diagenesis and contact metamorphism associated with diabase invasion. Typically, uranium interlaminar disseminates occur in fine-grained layers and in layers containing numerous textures and sutures and in finely veined parallel or transcutaneous stratification. Has identified crystalline uranium and uranium stone. Uranium origin is enriched during diagenesis-sedimentation, due to contact metamorphism and chlorite alteration. Diagenesis releases uranium from volcanic sediments and migrates to the surface
