Variations in the P‐T‐t of Deformation in a Crustal‐Scale Shear Zone in Metagranite

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Deformation in crustal‐scale shear zones occurs over a range of pressure‐temperature‐time (P‐T‐t) conditions, both because they may be vertically extensive structures that simultaneously affect material from the lower crust to the surface, and because ...

Estimation of P-T entrapment conditions of a subduction fluid using elastic thermobarometry: A case study from Cabo Ortegal Complex, Spain [PDF]

open access: yes, 2023
Fluid and mineral inclusions in metamorphic rocks allow the understanding of fluid-involved processes in subduction-zones providing essential contributions to the nature of geochemical processes and element cycling in present day subduction zones.

Timing of late Palaeoproterozoic metamorphism in the northern Belomorian Belt, White Sea region: Conclusions from U-Pb isotopic data and P-T evidence [PDF]

open access: yesBulletin of the Geological Society of Finland, 2001
Brilliant-looking zircon crystals from a garnet-amphibolitic, metamorphosed mafic dyke at Lyagkomina in the Lake Kovdozero area, northern Belomorian Belt, most probably mark the 1875±4 Ma age of peak late Palaeoproterozoic regional metamorphism which ...

P-T conditions of Pan-African orogeny in southeastern Nigeria [PDF]

open access: yesCentral European Geology, 2008
Abstract Different rock types from the area northeast of Obudu, southeastern Nigeria were investigated in order to place constraints on their metamorphic conditions. Detailed petrographic studies indicate four main rock groups in the studied area, namely migmatitic gneiss, migmatitic schist, granite gneiss and a minor amount of amphibolite, metagabbro ...

A re-evaluation of the peak P–T conditions of eclogite-facies metamorphism of the Paleozoic Acatlán Complex (Mexico) reveals deeper subduction

open access: yesScientific Reports, 2022
Eclogites in the Acatlán Complex, southern Mexico, record the subduction history of the complex. Previous studies indicate that the proto-Acatlán Complex reached

More On P-Union and P-Intersection of Neutrosophic Soft Cubic Set [PDF]

open access: yesNeutrosophic Sets and Systems, 2017
The P-union ,P-intersection, P-OR and P-AND of neutrosophic soft cubic sets are introduced and their related properties are investigated. We show that the P-union and the P-intersection of two internal neutrosophic soft cubic sets are also internal ...

An Experimental and Numerical Study of CO2–Brine-Synthetic Sandstone Interactions under High-Pressure (P)–Temperature (T) Reservoir Conditions

open access: yesApplied Sciences, 2019
The interaction between CO2 and rock during the process of CO2 capture and storage was investigated via reactions of CO2, formation water, and synthetic sandstone cores in a stainless-steel reactor under high pressure and temperature. Numerical modelling
