Vanishing Act: Experiments on Fission Track .Traduire cette page

Monazite sand grains were selected from a placer sand deposit, mounted in teflon, and polished. Grains were imaged with electron backscattering to characterize zoning patterns and variations in uranium concentration. Monazite grain mounts were etched in boiling 37% HCl for 50 minutes and fission track densities were determined using standard fission track counting techniques. Durango apatite ...

Monazite sand deposits are inevitably of the monazite-(Ce) composition. Typically, the lanthanides in such monazites contain Monazite powder about 45–48% cerium, about 24% lanthanum, about 17% neodymium, about 5% praseodymium, and minor quantities of samarium, 3. Monazite 3 gadolinium, and yttrium. Europium concentrations tend to be low, about 0.05%. South African "rock" monazite, from ...

TECHNICAL NOTE THE POINT OF ZERO CHARGE OF MONAZITE . · Fichier PDF

Monazite and xenotime are the two major rare-earth minerals widely distributed in heavy mineral sand in placer deposits. Both of them are recovered as by-products from the concentration of heavy minerals such as zircon, r-utile, and ilmenite. However, with some heavy mineral deposits, the valuable constituents are in a finer size range (less than 100 urn), for which the standard physical ...

CD5 monazite (age of 1574 ± 7 Ma) is restricted to the psammo-pelitic granulites, and marks final melt crystallization at the solidus during post-peak cooling (BM 1R stage, where R represents retrograde metamorphism). The metamorphic rim of CD6 monazite (age of 1539 ± 24 Ma) around partially resorbed CD5 domains is linked to the decomposition of BM 1 garnet during the terminal hydration ...
