A detailed and comprehensive TEM, EPMA and Raman characterization of high-metamorphic grade monazites and their U-Th-Pb systematics (the Góry Sowie Block, SW Poland)

Eleven monazite grains, two from a migmatitic gneiss and nine from two felsic in order to assess processes affecting U-Th-Pb age record. Two monazite grains from Raman results indicate moderate radiation damage. Monazite in...

New find monazite-(Nd) in sediments of the Drahany Upland

Authigenic monazite-(Nd)was found in greywackes from the Protivanov Formation, Drahany Upland. Monazite forms irregular aggregates up to 150 micrometers in diameter. Monazite aggregates enclose a variety of detrital and aut...

Monazite hydrothermal alteration during high temperature diagenesis of the greywackes from the Drahany Upplands (Bohemian Massif, Czech republic)

Detritic monazite-(Ce) is mediom to highly corroded by hydrothermal diagenetic fluids. Newly formed phases (rhabdophane-(Ce), synchysite-(Ce))were formed. Lead and medium to heavy REE are preferentially leached from the monazite....
