UPb geochronology of the Sri Lankan basement
TL;DR: In this paper, Baur et al. used upper-intercept ages of zircons from metapelites in the Highland Complex to establish a new geochronological framework, which is consistent with previously published work on SmNd model ages.
Journal ArticleDOI
Proterozoic crustal evolution of southernmost India and Sri Lanka
Ingo Braun,Leo M. Kriegsman +1 more
TL;DR: In this article, the Southern Granulite Terrain of India comprises four Proterozoic domains (from north to south): the Madurai Block, and the Achankovil, Ponmudi and Nagercoil Units.
Journal ArticleDOI
Two-feldspar geothermometry: a review and revision for slowly cooled rocks
TL;DR: In this article, a modified version of the Fuhrman and Lindsley (1988) programme was used to reverse the K−Na exchange and derive concordant temperatures.
Journal ArticleDOI
Single zircon ages, PT evolution and Nd isotopic systematics of high-grade gneisses in southern Malawi and their bearing on the evolution of the Mozambique belt in southeastern Africa
TL;DR: In this article, single zircon U−Pb and Pb-Pb ages and Nd isotope data for orthogneisses and metapelites collected around Lilongwe and farther south in the region around Blantyre and Zomba were reported.
Journal ArticleDOI
Ultrahigh-temperature Metamorphism (1150°C, 12 kbar) and Multistage Evolution of Mg-, Al-rich Granulites from the Central Highland Complex, Sri Lanka
Krishnan Sajeev,Yasuhito Osanai +1 more
TL;DR: In this article, a range of reaction textures indicative of a multistage P-T history following an ultra-high-temperature metamorphic peak was found in the central Highland Complex, Sri Lanka.

An experimental study of the effect of Ca upon garnet-clinopyroxene Fe-Mg exchange equilibria
D. J. Ellis,David H. Green +1 more
TL;DR: In this paper, a series of basaltic compositions and compositions within the simple system CaO-MgO-FeO-Al2O3-SiO2 have been crystallized to garnet-clinopyroxene bearing mineral assemblages in the range 24-30 kb pressure, 750°-1,300° C temperature.
Journal ArticleDOI
An experimental study of the partitioning of Fe and Mg between garnet and orthopyroxene
TL;DR: In this article, the effects of Calcium on Fe-Mg partitioning between garnet and orthopyroxene were investigated in the pressure-temperature range 5-30 kbar and 800-1,200° C in the FeO-MaggO-Al2O3-SiO2 (FMAS) and CaO-FeO-mgO-aluminous Orthopyroxenes (CFMAS) systems.

Thermodynamic calibration of geobarometers based on the assemblages garnet-plagioclase-orthopyroxene (clinopyroxene)-quartz
R. C. Newton,D. Perkins +1 more
TL;DR: Two mineralogic geobarometers based on the assemblage garnet-plagioclase-pyroxeneqvartz, common in granulite-grade quartzofeldspathic and basic lithologies, have been calibrated almost entirely from measured thermodynamic quantities, especially enthalpy of solution and heat capacity measurements as mentioned in this paper.

The Granulite Uncertainty Principle: Limitations on Thermobarometry in Granulites
B. Ronald Frost,Thomas Chacko +1 more
TL;DR: In this paper, three geothermometers based on reversed experimental data and applicable to granulites: the two-pyroxene, two-oxide, and garnet-clinopyroxene thermometers.

Thermal models for the magmatic accretion and subsequent metamorphism of continental crust
TL;DR: In this article, one-dimensional conductive relaxation models for the thermal evolution of continental crust which has undergone magmatic thickening in a predominantly recumbent tectonic regime are presented.
