Electron-microprobe age mapping of monazite
High resolution X-ray maps of Th, U, Pb, and Y in monazite can be used to construct age maps, which reveal the continuous spatial distribution of ages in a single grain of monazite. The age mapping algorithm and three examples are presented to illustrate the capabilities and applications of this mapping technique, the insights it can provide into monazite geochronology in general, and its limit...

Prograde suites of pelitic rocks were examined with electron microprobe INTRODUCTION and laser ablation inductively coupled plasma mass spectrometry to Monazite [(Ce,La,Th)PO4] plays an important role in determine the systematics of element partitioning between coexisting studies of igneous and metamorphic petrogenesis. Foremonazite, xenotime, and garnet. Monazite grains that grew in most, mona...
متن کاملMonazite Dating of Lunar Meteorite Nwa
Introduction. According to their textural and geochemical similarity it was suggested previously that the lunar meteorite NWA 4734 could be launch paired with Antarctic Mare basalts (LAP 02205/224/226/436-03632-04841) themselves possibly paired with NWA 032/470 lunar meteorites despite their different textures (1-5). A possible clue about the pairing issue is evidently their age. Method : After...
متن کاملSedimentological Analysis of Sands
This paper presents a practical sequence to study sand grains at the macroscopical scale. The approach consists of two mains phases, the recognition of the grains and the assessment of some of its characteristics. The method is validated on the dimensional features by comparison with a sieving procedure through the analysis of eight large sand samples of different locations.
متن کاملThe management of radiation hazards from the mining of mineral sands in Western Australia
This paper is concerned with the approach followed in Western Australian for dealing with the environmental hazards of ionising radiation associated with the mining and processing of titaniferous minerals contained in mineral sands deposits. There is a growing public awareness of the risks posed by one of these minerals, monazite, which emits low levels of radiation as it contains thorium and u...
