Titanite petrochronology linked to phase equilibrium modelling constrains tectono-thermal events in the Akia Terrane, West Greenland

On the Consistency of Thermal Events in the East Greenland/West Greenland Current System and off Labrador

Based on conductivity, temperature, depth (CTD) measurements with rosette mounted bottle performed along standard oceanographic sections off Greenland, the consistency of thermal events was analyzed. High consistency of events was found for the sections off Southeast Greenland and West Greenland, low consistency was revealed for the northernmost section off East Greenland and the West Greenland...

Phase-equilibrium constraints on titanite and rutile activities in mafic epidote amphibolites and geobarometry using titanite–rutile equilibria

Activities of titanite (Ttn, CaTiSiO5) and ⁄or rutile (Rt, TiO2) phase components were calculated for 45 well-characterized natural titaniteor rutile-undersaturated epidote–amphibolites by using the equilibria: (i) 3 anorthite + 2 zoisite ⁄ clinozoisite + rutile + quartz = 3 anorthite + titanite + water (referred to as TZARS) and (ii) anorthite + 2 titanite = grossular + 2 rutile + quartz (refe...

The current status of titanite–rutile thermobarometry in ultrahigh-pressure metamorphic rocks: The influence of titanite activity models on phase equilibrium calculations

Modelling Bidispersive Local Thermal Non-Equilibrium Flow

In this work, we present a system of equations which describes non-isothermal flow in a bidispersive porous medium under conditions of local thermal non-equilibrium. The porous medium consists of macro pores, and in the solid skeleton are cracks or fissures which give rise to micro pores. The temperatures in the solid skeleton and in the fluids in the macro and micro pores are all allowed to be...

Uniformity of the phase space and fluctuations in thermal equilibrium

General relations are found between the measure of the uniformity of distributions on the phase space and the first moments and correlations of extensive variables for systems close to thermal equilibrium. The role played by the parameter of the Renyi entropy for the analysis of their fluctuations and correlations is studied. Analytical results are verified and illustrated by direct simuations ...
