Whole-rock Geochemistry and Metamorphism of Blueschist/eclogite-facies Mafic Rocks on Syros, Cyclades, Greece
The island of Syros consists largely of possibly-repeated sequences of glaucophane-bearing calcareous schists, mafic schists, dolomite marbles, and calcite marbles containing abundant aragonite pseudomorphs (Dixon, 1969; Hecht, 1984). Several discrete, fault-bounded packages of blueschist/eclogite-facies mafic rocks with minor serpentinite are also found on the island. Although the mafic rocks ...
متن کاملLate Miocene–Pliocene eclogite facies metamorphism, D’Entrecasteaux Islands, SE Papua New Guinea
The D’Entrecasteaux Islands of south-eastern Papua New Guinea are active metamorphic core complexes that formed within a region where the plate tectonic regime has transitioned from subduction to rifting. While rapid, post 4 Myr exhumation and cooling of amphibolite and greenschist facies rocks that constitute the footwall of the crustal scale detachment fault system have been previously docume...
متن کاملAge Constraints for Emplacement of the Northern Cache Creek Terrane and Implications of Blueschist Metamorphism
Ophiolitic and accretionary units and associated blueschists of the Cache Creek terrane constitute the most complete evidence of a coherent subduction zone within the Canadian Cordillera. The rocks occupy a central position in the Intermontane Superterrane, a complex of arcs that includes most of the accreted crust in British Columbia (Figure 1). The Cache Creek terrane contains exotic fossil f...
متن کاملM . A . Forster Æ G . S . Lister Several distinct tectono - metamorphic slices in the Cycladic eclogite – blueschist belt , Greece
Several relatively thin tectono-metamorphic slices have been recognized in the Cycladic eclogite– blueschist belt, through detailed studies on Ios, Sifnos, Syros, and Tinos. A sequence of distinct metamorphic mineral growth events has been documented. These recur in each tectonic slice, although individual slices are dominated by different events. To constrain the timing of these processes, the...
متن کاملMelioidosis in New Caledonia
Recognized melioidosis-endemic areas are widening. In the South Pacific, melioidosis is endemic in New Caledonia, northern Australia, and Papua New Guinea. We report the first 4 documented cases of human melioidosis from New Caledonia. Molecular typing of 2 Burkholderia pseudomallei isolates suggests a link to Australian strains.
