P-T estimates of peak Bushveld metamorphism in the eastern Bushveld complex, Limpopo Province, South Africa : constraints from P-T pseudosections
… were performed on a refined number of samples, pseudosections for these samples were produced using Perplex. Electron microprobe analyses were used to analyze mineral chemistries of five samples and the resultant data used to construct isopleths for these samples in Perplex. The isopleth data …

N-S shortening during orogenesis in the Mt Isa Inlier: the preservation of W-E structures and their tectonic and metamorphic significance
… combined with textural relationships and P-T pseudosections, using key localities across the Eastern Fold Belt of the Mt Isa Inlier, has resolved the cause of the LP/HT signature. Measurement of FIAs in the Eastern Fold Belt has revealed phases of deformation and metamorphism that could not …

Microprobe dating of monazite in relation to porphyroblast growth and thermodynamic modelling P-T paths for rocks affected by prolonged orogenesis
… mineral growth for southeastern Vermont. P-T pseudosections were utilised to map mineral reactions for samples that contain garnet porphyroblasts with inclusion mineralogies that reveal partial mineral assemblages prior to garnet growth. Pseudosections were modelled in the system MnKFMASH for …

Structural and metamorphic evolution of the Robertson River metamorphics with pressure-temperature-deformation-time (P-T-D-t) path
… Isopleth thermobarometery, using P-T pseudosections in the MnNCKFMASH system for garnet porphyroblasts selected based on FIA trends in their core, reveal that the pressure increased progressively from 3- 4kb at 530º-550ºC to 6-7kb at 600º-620ºC during medium pressure temperature …

Metamorfismo ercinico di bassa-pressione: evoluzione tettonico-metamorfica del complesso di mandatoriccio (massiccio della Sila - Calabria)
… post-dated the Hercynian orogeny. P-T pseudosections show that micaschists and paragneisses of the Mandatoriccio complex followed a clockwise P-T path characterised by four main prograde phases: thickening, peak-pressure condition, decompression and peak-temperature condition. During …

Metamorphoseentwicklung im Kaokogürtel, NW-Namibia
Der Kaokogürtel in NW-Namibia gehört zu den panafrikanischen Orogensystemen Westgondwanas. Er besteht aus präpanafrikanischen Grundgebirgseinheiten und panafrikanischen vulkano-sedimentären Deckgebirgseinheiten, die einer grünschiefer- bis granulitfaziellen Metamorphose unterlagen. Für Metapelite …
