Monazite Microstructures and Their Interpretation in Petrochronology

open access: yesFrontiers in Earth Science, 2021
The phosphate mineral monazite (LREE,Y,Th,Ca,Si)PO4 occurs as an accessory phase in peraluminous granites and Ca-poor meta-psammopelites. Due to negligible common Pb and very low Pb diffusion rates at high temperatures, monazite has received increasing ...

Surface Mechanism of Fe3+ Ions on the Improvement of Fine Monazite Flotation With Octyl Hydroxamate as the Collector

open access: yesFrontiers in Chemistry, 2021
Froth flotation of fine minerals has always been an important research direction in terms of theory and practice. In this paper, the effect and mechanism of Fe3+ on improving surface hydrophobicity and flotation of fine monazite using sodium octyl ...

The absence of metamictisation in natural monazite [PDF]

open access: yesScientific Reports, 2020
AbstractThe actinide-containing mineral monazite–(Ce) is a common accessory rock component that bears petrogenetic information, is widely used in geochronology and thermochronology, and is considered as potential host material for immobilisation of radioactive waste.

A short-duration pulse of ductile normal shear on the outer South Tibetan detachment in Bhutan : alternating channel flow and critical taper mechanics of the eastern Himalaya [PDF]

open access: yes, 2007
In easternmost Bhutan the South Tibetan detachment (STD) is a ductile shear zone that juxtaposes the Radi (or Sakteng) klippe of the Tethyan Sedimentary Series from underlying high-grade Greater Himalayan rocks.

Radiological assessment of different monazite grades after mechanical separation from black sand

open access: yesScientific Reports, 2023
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-
