The Alada? melange is located between Mesozoic Tauride carbonate platform units and the Late Cretaceous Pozant?-Karsant? ophiolite its metamorphic sole. comprises a lower, mainly sedimentary unit, composed of variably disrupted thrust sheets deep-sea sediments, with localized matrix mass-flow turbidity current deposits. upper, volcanic-sedimentary highly basalt-pelagic carbonate-radiolarite uni...

In order to improve our understanding of the mineral potential of northern Vancouver Island beyond the wellknown intrusion-related Cu-Au-Ag(-Mo) porphyry deposits (e.g., Hushamu, MINFILE 092L 240 and the former Island Copper mine, MINFILE 092L 158) and base and precious-metal skarns (e.g., Merry Widow, MINFILE 092L 044), we need a better understanding of the stratigraphy of the Bonanza island a...

The transfer (accretion) of materials from a subducting oceanic plate to a subduction-accretionary complex has produced rock assemblages recording the history of the subducted oceanic plate from formation to arrival at the trench. These rock assemblages, comprising oceanic igneous rocks progressively overlain by pelagic sedimentary rocks (chert and/or limestone) and trench-fill clastic sediment...

The metamorphic sole rocks at the base of mantle peridotites from the Mersin ophiolite consist of amphibolites and metasedimentary lithologies. Mineral parageneses in the metamorphic sole rocks exhibit amphibolite and greenschist facies assemblages. Geothermobarometric studies based on mineral assemblages and chemical compositions of minerals indicate that average metamorphic temperature during...

Before its collision with Eurasia1–5, the Indian Plate moved rapidly, at rates exceeding 140mmyr−1 for a period of 20 million years1,3–7. This motion is 50 to 100% faster than the maximum sustained rate of convergence of themain tectonic plates today8. The cause of such high rates of convergence is unclear and not reproduced by numerical models9,10. Here we show that existing geological data11,...
