Blueschists and associated rocks in the south Sepik region, Papua New Guinea; field relations, petrology, mineralogy, metamorphism and tectonic setting
Blueschists in the South Sepik region of Papua New Guinea are one of several poorly known occurrences along the northern margin of New Guinea's Central Orogenic Belt. It is believed that they formed in a northward-dipping subduction zone, beneath a Palaeogene arc system now accreted along the north …

Geodynamic Evolution of the Aegean Back-arc and its Implication for Associated Precious and Base Metal Mineralization
… complexes. These two sources (Lower Cycladic Blueschist Nappe and Upper Cycladic Blueschist Nappe including the Cycladic Basement) correspond to known tectono-stratigraphic units of different provenance and age and help to correlate the basement over considerable distances, even where …

Advances in Subduction Zone Processes
… prograde metamorphism as it transitions from blueschist to eclogite facies resulting in the breakdown of volatile-bearing minerals and producing anhydrous minerals and a free fluid phase. Previous works attempting to understand the evolution of subducted lithologies have provided a firm …

Applications of Elastic Modeling, Thermobarometry, and Thermal History Modeling to (Ultra)high-Pressure Metamorphic Rocks
… ((U)HP) metamorphic rocks, such as blueschists and eclogites, are formed during metamorphism of subducted crust and sediments along relatively cold geothermal gradients. (U)HP metamorphic rocks may be incorporated into the subduction zone accretionary wedge and exhumed, thereby …

THE INTERPLAY BETWEEN CATION ORDERING AND ELASTICITY OF OMPHACITES TO UNRAVEL PTT PATHS OF METAMORPHIC ROCKS
… minerals of eclogites and is also found in blueschist facies and ultra-high-pressure rocks. Its widespread occurrence makes it a valuable candidate for Raman elastic geothermobarometry, a method that uses the deformation recorded by mineral inclusions to determine the pressure and …
