Phase equilibrium modelling and zircon-monazite geochronology of HT-UHT granulites from Kambam ultrahigh-temperature belt, south India
TL;DR: In this paper , the authors present the P-T-t evolutionary history of garnet-cordierite-spinel granulites from different localities in the Madurai block.

Neoproterozoic Mafic Magmatism in Nagercoil Block, Southern India and Its Implications on the Gondwana Collisional Orogeny
TL;DR: In this paper , petrology, geochemistry, and zircon U-Pb/Hf isotopic data of gabbros from the Nagercoil block were used to understand their petrogenesis and tectonic significance.
Age and petrogenesis of mafic granulites from central Madurai block, south India: implications on regional tectonics
TL;DR: In this paper , the authors present detailed petrology, geochemistry and geochronology of representative mafic granulites from the area to understand their petrogenesis and tectonic setting.

Petrological, geochemical and geochronological evolution of massif type charnockite from the Eastern Ghats Province, India: Implications on the regional tectonics of the Rayner-Eastern Ghats orogeny
TL;DR: In this article , U-Pb analysis on oscillatory zoned zircon domains from eight samples yields crystallization ages for the charnockite, which can be correlated with the tectonometamorphic evolution of the province.

Zircon trace element geochemistry: partitioning with garnet and the link between U–Pb ages and metamorphism
TL;DR: In this article, the trace element distribution coefficients between zircon and garnet were analyzed for trace elements using LA-ICP-MS and SHRIMP ion microprobe.
Journal ArticleDOI
Computation of phase equilibria by linear programming: A tool for geodynamic modeling and its application to subduction zone decarbonation
TL;DR: In this article, an algorithm for the construction of phase diagram sections is formulated that is well suited for geodynamic problems in which it is necessary to assess the influence of phase transitions on rock properties or the evolution and migration of fluids.
Journal ArticleDOI
New thermodynamic models and revised calibrations for the Ti-in-zircon and Zr-in-rutile thermometers
John M. Ferry,E. B. Watson +1 more
TL;DR: In this paper, the authors show that the Zr content of rutile coexisting with zircon increases with decreasing the activity of SiO2 and demonstrate that the substitution of Ti in Zircon is primarily for Si.
Journal ArticleDOI
The origins of granulites: a metamorphic perspective
TL;DR: A thorough survey of over 90 granulite terranes or occurrences reveals that over 50% of them record P-T conditions outside the 7.5 ± 1 kbar and 800 ± 50 °C average granulites regime preferred by many authors as discussed by the authors.
