Energy, Waste and the Environment: A Geochemical Perspective
Rare earth element distribution patterns of the sandstones enclosing the U ore
and Sm-Nd isotope data of groundwater suggest that fissio- genic REE were
mobilized due to dissolution of uraninite and migrated over at least 3 m but less
than ...

Are Round Uraninite Grains Detrital? The interpretation of round uraninite grain
shapes is controversial. Davidson (1960, p. 155) drew attention to round
pitchblende grains in vein deposits from Freiberg, Germany. More recently

Euhedral and massive pyrite associated with uraninite and galena are
considered penecontemporaneous with the mineralization. Detailed study of the
iron sulfides shows that those associated with mineralization have been enriched
in cobalt ...

economic grade. However, the new mineralogical evidence for the origins of
uraninite and pyrite is not in agreement with anoxygenic or reducing atmospheric
conditions 2.8-2.0 b.y. ago. Thus an alternative reason is necessary to explain

The Chemical Evolution of the Atmosphere and Oceans
The mineralogical, petrographic, sedimentologic, and geochemical data that
point to a detrital origin for much of the uraninite in the conglomerates of the
Witwatersrand and in the Blind River-Elliot Lake region are weighty, and the
implications ...

Crystalline uraninite (U02) is intergrown with skeletal crystals of siegenite (with
the general formula (R2R23S4) where R2 = Fe, Ni, Co, Cu and R3 = Co, Ni, Cr).
The intergrowth simulates a simultaneous crystallization intergrowth. However ...

Field Guide to Rocks & Minerals of Southern Africa
Uraninite is a heavy, radioactive ore mineral, the radioactivity caused by the
presence of uranium. It forms cubic or octahedral crystals that are normally dark-
brown to black. Uranium is used in nuclear power stations and in the medical
field.

Late uraninite, coffinite or calcite fills numerous fractures in the pitchblende
veinlet. In the intensively fractured parts of the veinlet, galena crystals, up to 3 mm
in size, are common and the uraninite/coffinite ratio drops dramatically. Native
