This chapter focuses on phosphates that are significant in metamorphic rocks. A quick
survey of phosphate mineral descriptions at a commercial mineral web-site revealed over …

High-temperature metamorphic rocks are the result of numerous chemical and physical
processes that occur during a potentially long-lived thermal evolution. These rocks chart the …

Laser-ablation split-stream (LASS) analysis—high-speed, high spatial-resolution,
simultaneous isotopic and elemental analysis—enables petrochronology at a new level …

We report measurements of Pb diffusion in both synthetic (CePO4) and natural monazites
run under dry, 1-atm conditions. Powdered mixtures of prereacted CePO4 and PbZrO3 were …

Abstract Monazite [(Ce, LREE, Th, U, Ca)(P, Si) O 4], with complex zoning in Th and other
elements, is commonly observed in metamorphic and igneous rocks. The hypothesis that …

Prograde suites of pelitic rocks were examined with electron microprobe and laser ablation
inductively coupled plasma mass spectrometry to determine the systematics of element …

Progressive Early Silurian low‐pressure greenschist to granulite facies regional
metamorphism of Ordovician flysch at Cooma, southeastern Australia, had different effects …

The Main Central Thrust (MCT) juxtaposes the high‐grade Greater Himalayan Crystallines
over the lower‐grade Lesser Himalaya Formation; an apparent inverted metamorphic …

The dominant occurrence of phosphate minerals in crystalline rocks is as accessory phases,
most notably apatite, monazite, and xenotime. Because these minerals tend, to varying …

Monazite growth and composition has been modeled in the system K2O–Na2O–CaO–MnO–
MgO–FeO–Al2O3–SiO2–H2O–Y2O3–Ce2O3–P2O5–F and a pseudosection is presented …
