The closed system ages were calculated from the measured Th 230 /U 234 and Pa 231 /U 235 activity ratios. Because of discordances found between the Th 230 and Pa 231 ages of many of the shell samples analyzed, it was assumed that shells do not usually form an …

A bibliography of 479 references encompassing the fields of uranium and thorium geochemistry and mineralogy, geology of uranium deposits, uranium mining, and uranium exploration techniques has been compiled by the Ecological Sciences Information Center of Oak Ridge National Laboratory. The bibliography was produced for the National Uranium The latest decades uranium exploration in South China has gotten some new discovery in granite uranium deposit,beside the silicification zone type and siliceous vein type mineralization(100 Ma),there is an elder type mineralization(100 Ma).Based on the detail former study,this paper more confidently identifies this elder type mineralization as sericitic alteration rock type.

Uranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust.Uranium is one of the more common elements in the Earth's crust, some 40 times more common than silver and 500 times more common than gold. [1] It can be found almost everywhere in rock, soil, rivers, and oceans. [2] The challenge is to find those areas where the concentrations are adequate to … Uranium deposits in these primary rocks are usually unattractive owing to their low uranium values (generally 100--300 ppm) and high thor• ium:uranium ratios. In Iran. uraninite veins have been identified within fenitised wall-rocks surrounding Alpine carbonatitic dykes. The gangue mineralogy within these uraninite veins is a combination of one or more of the following: aegirine. riebeckite. albite. and …

In a pair of well- and poorly-drained soils developed on Ordovician carbonate rocks in Central Pennsylvania, the distribution with depth and chemical form of 238 U, 232 Th, and 226 Ra have been compared to soil properties. Concentrations range from 3.3 to 8 ppm U and 6.3 to 11 ppm Th in the soils.

So I would like to know if such has ever been found, or if it's possible to have uranium deposits so near to the ocean.
