New Mechanism of the Formation of the Uranium-Titanium Association in Ores of Paleovalley Deposits

摘要

Uranium-titanium association in ores of paleovalley deposits demonstrates space and genetic control of uranium mineralization by clastogene iron-titanium oxides (typically modified ilmenites); this link is more preferable than that to carbonaceous matter and iron sulfides. Ore-bearing uranium-titanium association is most widely abundant in paleovalley deposits of North America (sandstone type) located in alluvial sandstone enriched in iron-titanium oxides with a wide age range from the Miocene in Southern Texas to the Late Jurassic in New Mexico [1,2].
