Since their recent first record within the Egyptian Nubian Shield, auriferous and uraniferous
marbles (Au= 0.98–2.76 g/t; U= 133–640 g/t) have rarely been addressed, despite not only …

The Um Ara area, in the south Eastern Desert of Egypt contains a number of uranium
occurrences related to granitic rocks. U-rich thorite, thorite and zircon are the main primary …

Wet climatic episodes are known to have prevailed in the Egyptian Sahara several times
during the late Quaternary, most recently during the Holocene 8000 yr ago. Earlier wet …

An alkaline brine containing uranyl (UO22+) leaked to the thick unsaturated zone at the
Hanford Site. We examined samples from this zone at microscopic scale to determine the …

The present work aims at identifying Nb-Ta-, Zr-Hf-, REE-, Th-U-bearing two-mica granite
from geological, geophysical cross-sections and mineral chemistry studies from three …

MIS 3 environmental conditions in Africa north of the Equator and the Arabian Peninsula
have long been controversial due to data scarcity and methodological caveats. In this paper …

Electron microprobe analysis (EMPA) and microscopic investigations were performed on
monazite grains from the black sand deposits of northern Sinai beach. Electron microprobe …

The present study is an application of a radiochemical procedure for the determination of
238U, 235U and 234U as well as uranium isotopic ratios in El Sela ore grade samples that …

The present work aims to integrating detailed geologic field studies with natural
radionuclides activity ratios as a tool for studying uranium-mobility in three rock types at El …
