On the importance of minding one s Ps and Ts: metamorphic processes and quantitative petrology
This Special Issue comprises a selection of the papers given at a two-day discussion meeting held at the University of Melbourne, Australia in June 2009 to celebrate Roger Powell s 60th birthday. At this milestone, it is fitting to review Roger s career to date. He has published 200 scientific papers on topics that range from lowto high-grade metamorphism, from lowto ultrahigh-pressure (UHP) me...
متن کاملThe contribution of metamorphic petrology to understanding lithosphere evolution and geodynamics
In the early 1980s, evidence that crustal rocks had reached temperatures >1000 C at normal lower crustal pressures while others had followed low thermal gradients to record pressures characteristic of mantle conditions began to appear in the literature, and the importance of melting in the tectonic evolution of orogens and metamorphicemetasomatic reworking of the lithospheric mantle was realize...
متن کاملEvidence from ophiolites, blueschists, and ultrahigh-pressure metamorphic terranes that the modern episode of subduction tectonics began in Neoproterozoic time
Earth is the only known planet with subduction zones and plate tectonics, and this fact demonstrates that special conditions are required for this mode of planetary heat loss. Sinking of cold, dense lithosphere in subduction zones is the principal plate-driving force, so plate tectonics could not have begun until Earth cooled sufficiently to allow lithosphere to collapse into the underlying ast...
متن کاملCharacteristic thermal regimes of plate tectonics and their metamorphic imprint throughout Earth history: When did Earth fi rst adopt a plate tectonics mode of behavior?
Where plates converge, one-sided subduction generates two contrasting thermal environments in the subduction zone (low dT/dP) and in the arc and subduction zone backarc or orogenic hinterland (high dT/dP). This duality of thermal regimes is the hallmark of modern plate tectonics, which is imprinted in the ancient rock record as penecontemporaneous metamorphic belts of two contrasting types, one...
متن کاملFrom Continental Drift to Plate Tectonics
SINCE THE l6TH CENTURY, CARTOGRAPHERS HAVE NOTICED THE jigsaw-puzzle fit of the continental edges. Since the 19th century, geologists have known that some fossil plants and animals are extraordinarily similar across the globe, and some sequences of rock formations in distant continents are also strikingly alike. At the turn of the 20th century, Austrian geologist Eduard Suess proposed the theor...
