Location, Location, Location: Monazite Behaviour During UHT Metamorphism and Melt Crystallization
ABSTRACT Monazite is a robust mineral for recording the suprasolidus evolution of migmatites and granulites. However, monazite commonly has diverse compositions and yields variable dates in a single sample; understanding the controls on monazite behaviour and composition during partial melting and melt crystallization are not always straightforward ...

P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)
ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,

Pegmatites of the Mokromoskovsk granite pluton
Introduction. The Mokromoskovsky pluton is composed of light gray granites and dark gray granodiorites. Light gray granites are composed of oligoclase (35-40%), microcline (20-25%), quartz (30-35%), and biotite (2-5%).

Multiseasonal and geobotanical approach in remote detection of greisenization areas in the Serra da Pedra Branca Granite, Goias State, Brazil [PDF]
Multiseasonal analysis of LANDSAT multispectral images in CCT format permitted the mapping of lithologic facies in the Pedra Branca Granite, using geobotanical associations, which occur in the form of variations in the density of cerrado vegetation, as ...

Análisis del tratamiento en medio ácido de partículas de pizarra
Slate particles were treated in liquid acid medium. The results were analyzed as a function of the disolved ions and specific surface area values. Infrared spectroscopy (FT-IR) and X- ray difraction were also used in this study.
