To investigate the influence of hydration on brittle deformation oceanic crustal rocks, we conducted triaxial experiments gabbroic rocks with various degrees at a confining pressure 20 MPa and room temperature, measuring elastic wave velocity. Hydrated olivine gabbros reached maximum differential stress 225–350 MPa, which was considerably less than those recorded for (~450 MPa), but comparable ...

In the Southern São Francisco Craton near Itapecerica (Minas Gerais – Brazil) occurs a supracrustal succession of rocks, varying from bottom to top by quartzite, graphite schist, khondalitic paragneiss and banded iron formation whose protoliths are oceanic basin with ages in context Rhyacian-Orosirian orogeny. Amphibolite metaultramafic bodies occur associated this succession. Mineralogical tex...

A tectonic window into the upper 2,000 m of oceanic crust generated at superfast spreading (∼142 mm/yr) southern East Pacific Rise exposes a continuous layered structure basaltic lavas and sheeted dikes over gabbroic rocks. This relatively simple is in accord with expectations for crustal accretion very fast rate high magma budget where magmatic construction keeps pace plate separation. Detaile...

The oldest rocks in the Avalonian Antigonish Highlands of northern mainland Nova Scotia, Canada, are late Neoproterozoic (>618 Ma) volcanic and sedimentary Georgeville Group intruded by gabbroic/dioritic to granitic plutons. New U–Pb zircon ages presented here for five samples from plutons into James River (or) Keppoch formations have ranging ca. 615 604 Ma. They petrological characteristics...

Abstract Brown amphibole is a minor but common mineral component in lower oceanic crust. It generally interpreted as products of migrating SiO2 and H2O-rich fluids or melts, which can be either residual melts from advanced magmatic differentiation Mid-Ocean Ridge Basalt (MORB), hydrothermal including seawater component. Within the crust exhumed at Atlantis Bank Oceanic Core Complex, along ultra...

purpose the aim of this study was to determine the effect of ramadan fasting on body composition, calorie intake and physical performance in young female athletes undertaking training sessions during ramadan. methods twelve voluntary female athletes (15-27 years old) were assigned to the research. a prospective study was conducted to investigate the athletes on four different occasions: one wee...

samples of grass pea seed (lathyrus sativus) were prepared and analyzed for some chemical composition and as well for their anti-nutritional factors. the rumen degradability coefficients and post ruminal digestibility of dry matter and crude protein of unheated vs. oven heated samples were determined, employing in situ and in vitro techniques. results indicated that grass pea seed contained a c...

evaluation of four safflower (carthamus tinctorius l.) genotypes for oil content and fatty acidcomposition showed that oil content varied from 22.16 to 34.39% and the highest seed oilcontent was obtained from isfahan14 genotype (34.39%, respectively). among those fatty acidswere detected, linoleic acid (75.81- 77.86%) was the predominant fatty acid followed by oleic(12.57–13.75%), palmitic (6.0...
