与金、黄铁矿、少量其他金属硫化物、重矿物和碳氢化合物共生的晶质铀矿矿床,产于四个相互不整合的前寒武纪岩系的礫岩中。含矿礫岩常产于沉积间断面上,或者在区域不整合面上。区域变质作用使礫岩原来的一些组份及其间的关系变得模糊不清。在礫岩基质中,在金属矿物和其他构造间有复杂的连生,有侵蚀和交代现象,就象在热液成因的金属矿床中一样。矿石的分布与断层和其他交错构造无关,但与沉积特征有紧密的关系。本文提出了一些实际证据,表明在礫岩沉积过程中或者在其沉积之后立即发生了铀和金的成矿。
Crystalline uranium deposits symbiotic with gold, pyrite, small amounts of other metal sulfides, heavy minerals and hydrocarbons are found in conglomerates of the four unconformity Precambrian rocks. Ore containing conglomerates are often found on sedimentary facies, or on unconformities. Regional metamorphism obscures some of the original components of conglomerates and their relationships. In conglomerate matrices, there are complex intergrowth, erosion and metasomatism among metallogenic minerals and other structures, just as in hydrothermal-induced metallogenic deposits. Ore distribution is not related to faults and other interlaced structures, but closely related to sedimentary characteristics. This paper presents some practical evidence that uranium and gold mineralization occurred during or immediately after deposition of conglomerates.
