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 …

Monazite is a light rare earth element (LREE)-bearing phosphate mineral that is present in a
wide variety of rock types, has an extremely variable composition reflecting host rock …

Laser-ablation ICPMS has become widely accessible as a powerful and efficient multi-
element microanalytical technique. One of its key strengths is the ability to analyse a wide …

High mass resolution multicollector inductively coupled plasma mass spectrometry (MC-ICP-
MS) was assessed for iron isotope measurement of natural samples after matrix separation …

Abraded fragments (200–400 μm) of a large, chemically homogeneous, and non-metamict
Brazilian monazite crystal, characterised by a concordant U–Pb ages of 474±1 Ma …

Hydrothermal monazite is one of the most reliable geochronometers for U-Pb dating of
epigenetic or hydrothermal ore deposits because its blocking temperature, at ca. 700° C, is …

Low-temperature alteration of monazite is documented in three centimeter-sized monazite
crystals from Norway (Arendal), Madagascar (Ambato), and Sri Lanka. The three crystals …

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 …

Zircons from the polyphase Tamlalt–Menhouhou gold deposit were examined in order to
define the age of the sodic metasomatism (albitization), which is assumed to be related to …
