“…Metamorphic P-T conditions of the basaltic eclogites found among metasedimentary rocks have been estimated using of classical exchange thermo-and barometers and phase diagram calculations using the JUN92.bs database file and THERIAK-DOMINO software package (De Capitani & Brown, 1987;De Capitani & Petrakakis, 2010). Applying the classical geothermobarometric tools (Carswell & Harley, 1990;Krogh, 2000;Newton & Smith, 1967;Råheim & Green, 1974) on garnet-clinopyroxene pairs of well-preserved eclogite samples (Van 95), provide pressures ranging from 1.9 to 2.4 GPa and temperatures spanning 480-540°C (Figure 4).…”

Late Cretaceous eclogitic high-pressure relics in the Bitlis Massif

et al. 2013

A new occurrence of eclogites was found in the Kesandere valley in the eastern most part of the Bitlis complex, SE Anatolia. These high-pressure (HP) relics were preserved in calc-arenitic metasediments within the high-grade metamorphic basement of the Bitlis complex. The eclogitic parageneses were strongly overprinted during decompression and heating. These new eclogites locality complements the evidence of blueschist-facies metamorphism documented recently in the meta-sedimentary cover sequence of this part of the Bitlis complex. Thermodynamic calculations suggest peak conditions of ca. 480-540°C/1.9-2.4 GPa. New U/Pb dates of 84.4 ± .9 and 82.4 ± .9 Ma were obtained on zircons from two Kesandere eclogite samples. On the basis of geochemical criteria, these dates are interpreted to represent zircon crystallization during the eclogitic peak stage. Kesandere eclogites differ from those previously described in the western Bitlis complex (Mt. Gablor locality) in terms of lithologic association, protolithic origin, and peak P-T conditions (600-650°C/1.0-2.0 GPa, respectively). On the other hand, eclogitic metamorphism of Kesandere metasediments occurred shortly before blueschist-facies metamorphism of the sedimentary cover (79-74 Ma 40 Ar/ 39Ar white mica). Therefore, the exhumation of Kesandere eclogites started between ca. 82 and 79 Ma, while the meta-sedimentary cover was being buried. During this short time span, Kesandere eclogite were likely uplifted from~65 to 35 km depth, indicating a syn-subduction exhumation rate of~4.3 mm/a. Subsequently, eclogite-and blueschist-facies rocks were likely retrogressed contemporarily during collision-type metamorphism (around 72-69 Ma). The Bitlis HP rocks thus sample a subduction zone that separated the Bitlis-Pütürge (Bistun?) block from the South-Armenian block, further north. To the south, Eocene metasediments of the Urse formation are imbricated below the Bitlis complex. They contain (post Eocene) blueschists, testifying separation from the Arabian plate and southward migration of the subduction zone. The HT overprint of Kesandere eclogites can be related to the asthenospheric flow provoked by subducting slab retreat or break off.

“…Also pseudosections are powerful tools to: (1) check and visualize the implications of thermodynamic databases; (2) develop new equations of state and solution models; (3) plan new experimental work and (4) understand natural systems. In this paper computer program THERMOCALC [8] [9], GIBBS [10] [11] [12] and THERIAK-DOMINO [13] are discussed and pseudosections are generated on some chemical data taken from the published literature from the Himalaya and Alps and also new chemical and EPMA data generated from the Garhwal Himalaya to demonstrate the capabilities of THERMOCALC and THERIAK-DOMINO.…”

In this paper computer program THERMOCALC, GIBBS and THERIAK-DOMINO are discussed and pseudosections are generated on some chemical data taken from the published literature from the Himalaya and Alps and also new chemical and EPMA data generated from the Garhwal Himalaya to demonstrate the capabilities of THERMOCALC and THERIAK-DOMINO. Usefulness and limitations of computed pseudosections (equilibrium assemblage diagrams) with THERIAK-DOMINO and THERMOCALC in understanding evolutionary history of metamorphic rocks are discussed

“…With the advent of comprehensive thermodynamic datasets and advanced computer protocols (Powell & Holland, 1988;Connolly, 1990;Powell et al, 1998;de Capitani & Petrakakis, 2010), phase equilibria modelling has become accessible to everyone in their pursuit of P-T conditions and P-T-t paths, and in understanding the development and evolution of mineral assemblages. Phase equilibria modelling of crustal melting is possible for peraluminous protolith compositions (White et al, 2001(White et al, , 2007, such as pelites and granites, and has led to advances in understanding crustal melting and the evolution of residues-migmatites and granulites-after melt loss.…”

Introduction to a virtual special issue on crustal melting

Journal Metamorphic Geology

View full text Add to dashboard Cite

This virtual special issue represents a collection of papers concerning Crustal Melting selected by the Editor from those published on various aspects of this theme in the JMG since 1982. The papers are grouped into sequences that address topics that have been prominent in the JMG during the last 30 years concerning the origin, evolution and tectonic role of migmatites and migmatitic granulites in crustal evolution. These topics are: Open-and closed-system processes in the formation of migmatites and migmatitic granulites; thermobarometry, P-T paths, phase equilibria modelling and retrograde processes in formerly melt-bearing rocks; geochronology in partially melted rocks; and, microstructures, deformation and tectonics of melt bearing rocks.About one-third of the papers published in the JMG since its inception concern the origin, evolution and tectonic significance of migmatites and migmatitic granulites in crustal evolution, including the first special issue published by the JMG concerning ÔStudies in the genesis and deformation of migmatitesÕ edited by Tracy The selection of papers in this virtual special issue is by no means comprehensive, but it is intended as a representative selection of what has been published in the JMG over 30 years to give the reader a broad overview of crustal melting. Furthermore, although many papers address more than one topic, each is included only once and has been placed within the most appropriate section.
