本文应用概率图的研究方法,对东南地洼区内若干铀矿床范围内赋存铀矿体的上震旦统——下寒武统各层铀量,进行概率分布的系统研究,获得了区域及矿床范围内地层形成初始状态的含铀量数据(底数),从而得出本区云硅泥岩型铀矿床并非沉积成岩所成的认识,比较赋矿层与上下岩层铀量底数表明,赋矿层具有较高的含铀底数,可能是矿床的铀源层,各层位铀量呈多峰型混合分布及多总体的事实,证明区内本类型铀矿床是在具有铀源层的基础上,经后期成矿作用的迭加、改造或再造而成。 本文通过四个矿床实例,从矿床元素的概率分布这一侧面,提供一定信息,论证东南地洼区内云硅泥岩型铀矿床属于多因复成铀矿床。
In this paper, we use the method of probability map to systematically study the probabilistic distribution of uranium in the Upper Sinian-Lower Cambrian layers of uranium ore bodies within the range of several uranium deposits in the southeast Diwak region, And the uranium content data (base) of the initial formation of the strata in the deposit area, and then conclude that the cloud-silicate uranium deposit in this area is not an understanding of sedimentary diagenesis. Comparing the base amounts of uranium in the ore-dressing layer and the upper and lower strata shows that the ore-dressing layer has The higher uranium base number may be the uranium source layer of the deposit, the multi-peak mixed distribution of uranium in each layer and the fact that it is multi-aggregated. It is proved that this type of uranium deposit in this area is based on uranium source, Late mineralization superimposed, transformed or reborn. In this paper, we provide some information from the side of probability distribution of deposit elements through four ore deposit examples. It is concluded that the cloud-silicon and mudstone-type uranium deposit in the dike area of the southeast depression belongs to the multi-factor complex uranium deposit.
