,U-Ore Mineralization of Hypergenesis Reduction Zone: Uranium “Blacks”,eralogical ATEM-studies of loose black U-mineralization show that uranium black’s composition can be represented by at least three different mineral forms: oxide (uraninite of different degrees of crystallinity), silicate (coffinite) and phosphate (ningyoite).泥瓦匠 发表于 2025-3-23 16:07:45

,U-Ore Mineralization of Hypergenesis Reduction Zone: Uranium “Blacks”,ium-ore accumulations in the hypergenesis region (have been identified by L.N. Belova) was described. Examples of typical uranium mineral zones manifestation in nature (at known U-deposits) are shown in the table. Processes of hypergenic zonality formation by uranium minerals have been looked and sc表示问 发表于 2025-3-24 09:11:48
New Minerals Family: U4+-Phosphates,tion on U.-phosphates has been systematized and generalized. Here optical, chemical and structural minerals characteristics were summarized in a single table. These phases’ mineralogical characteristics (morphological and crystallochemical) and their occurrences described. The first section summariz不连贯 发表于 2025-3-24 11:28:30
Some Aspects of Uranous (U4+) Mineralogy in the Light of Crystallochemical ATEM Data,nd Brockite (samples Fersman Mineralogical Museum, Moscow) have been analyzed together with the literature data on rhabdophane-like minerals. Existing systematization in this mineral group have been clarified. Questions of isomorphism and systematics of phosphates in Rhabdophane mineral group are co呼吸 发表于 2025-3-24 17:18:03
Paleochannel Sandstone-Type Uranium Deposits of Vitim Ore Region,ium ore region, Russia. All deposits belong to sandstone economic type, basal channel subtype; in Russian it commonly called as paleovalley, paleo-riverbed or paleo-streambed. Here predominant ore component is ningyoite in crystalline and mineraloid form. These ores, little-known previously and unkn牛马之尿 发表于 2025-3-24 22:28:30
