-
(2006)Recent hydrothermal Fe-oxyhydroxide precipitates (ochres) were sampled during two submersible expeditions to the NE part of the Marsili Seamount summit (SE Tyrrhenian Sea). The Marsili ochres belong to type 1 primary ...
-
(2006)The magmatic processes leading to porphyry-Cu mineralization at Santa Rita are reconstructed on the basis of petrographic studies, thermobarometry, and laser-ablation inductively-coupled-plasma mass-spectrometry analyses ...
-
(2006)We present new mineral and whole-rock compositions and Sr-Nd-Hf-Pb-O-H isotope data on samples from the Kangerlussuaq Alkaline Complex (~ 1000 km2) in central East Greenland, part of the North Atlantic Igneous Province. ...
-
(2006)Andesitic to dacitic magmas of the Plat Pays volcanic complex (Dominica, Lesser Antilles) that erupted during the last ~100 ka equilibrated at temperatures of 800-880 °C and total pressures of 1.1-2.3 kbar. Magmatic ...
-
(2006)The Küre ophiolite is interpreted as the remnants of the suprasubduction marginal basin formed on the northwardly subducted Tethyan oceanic lithosphere. The Küre Basin was opened during late Late Triassic and closed during ...
-
(2006)The Popolasca-Francardo area of northern Corsica contains an assemblage of continental tectonic units affected by an Alpine deformation. In one of these units, Unit 11, previously regarded as weakly metamorphosed, a ...
-
(2006)The evolution of pre-failure damage in brittle rock samples subjected to differential compression has been investigated by means of acoustic emission (AE) records. The experimental results show that the damaging process ...
-
(2006)We present a detailed palaeoclimate analysis of the Middle Miocene (uppermost Badenian-lowermost Sarmatian) Schrotzburg locality in S Germany, based on the fossil macro- and micro-flora, using four different methods for ...
-
(2006)During the 2001 eruptive episode three different magmas were erupted on the southern flank of Mount Etna volcano from distinct vent systems. Major and minor element chemistry of rocks and minerals shows that mixing occurred, ...
-
(2006)We report the results of a geochemical study of the Jijal and Sarangar complexes, which constitute the lower crust of the Mesozoic Kohistan paleo-island arc (Northern Pakistan). The Jijal complex is composed of basal ...
-
(2006)Tiny basaltic samples containing finely grained titanomagnetite with Curie temperature less than 100°C were heated in air in weak field (25-100μT) at temperatures between 400°C and 560°C for times as long as 32 hr. ...
-
(2006)The Saldanha hydrothermal field is located at the top of a serpentinized massif (Mount Saldanha, MS) at a non-transform offset (NTO5) along the Mid-Atlantic Ridge (MAR), south of the Azores. It is one of the rare known ...
-
(2006)We report here a multiphase mineral inclusion composed of quartz, plagioclase, K-feldspar, sapphirine, spinel, orthopyroxene, and biotite, in porphyroblastic garnet within a pelitic granulite from Rajapalaiyam in the Madurai ...
-
(2006)We report here a garnet-spinel orthopyroxenite in close association with an ultrahigh-temperature (UHT) granulite from the central part of the Madurai Granulite Block in southern India. The garnet-spinel orthopyroxenite ...
-
(2006)Highly aluminous orthopyroxene, coexisting with sapphirine, cordierite, sillimanite, quartz and garnet in various combinations, constitute granoblastic mosaic peak metamorphic assemblages in aluminous granulites from three ...
-
(2006)Eclogites within the Tromsø Nappe of the Uppermost Allochthon in the Scandinavian Caledonides record a complex P-T history, involving a prograde subduction-related stage. Information on the early prograde stage of the ...
-
(2006)Sapphirine+quartz-bearing pelitic granulites, garnet-clinopyroxene-quartz-bearing mafic granulites and quartzo-feldspathic granulites with corundum-garnet-quartz constitute rare but important members of the Highland Complex ...
-
(2006)Eclogite and garnet glaucophanite lenses from the Punta Balandra unit of the Samaná basement complex (northern Hispaniola) preserve information of the early metamorphic and tectonic history of subduction in the Caribbean ...
-
(2006)The Southern Indian shield is a classic terrain that may be regarded as a model for Precambrian crustal evolution. The Palni Hills represent a portion of the granulite-facies terrain of the Madurai block. Determination of ...
-
(2006)Seismic velocities and attenuations are influenced by lithology, porosity and permeability as well as the kind and quantity of the pore fluids. The microstructure of rocks is another important factor influencing seismic ...
