REE-bearing minerals in Drava river sediments, Slovenia, and their potential origin
Monazite and xenotime are major ore minerals for rare earth elements (REE), Y, and actinides, a powerful tool for radiometric dating and indicators of the geological genesis of the parent rock.

Radiological assessment of different monazite grades after mechanical separation from black sand
In Egyptian black sands, monazite is a precious mineral characterized by its composition, which includes crucial constituents such as thorium, trace amounts of uranium, and rare earth elements. It is essential to evaluate and quantify the extent of gamma-

New monazite U-Pb age constraints on the evolution of the Paleoproterozoic Vaasa granitoid batholith, western Finland [PDF]
The Vaasa batholith, western Finland, is a large, peraluminous granitoid pluton that crystallized at 1.88–1.87 Ga during the culmination of the Svecofennian orogeny.

MINERALOGY AND GEOCHEMISTRY OF CHLORITHOLITES FROM THE NEPRYAKHINO GOLD FIELD, SOUTH URALS [PDF]
The chlorite rocks (chloritolites) exposed in a bedrock of the Mokhovoe boloto (Moss swamp) gold placer (East Uralian Megazone, South Urals), which occurs on ultramafic rocks, are studied.
