Webb2 feb. 2016 · We present geochemical data to identify the tectonic setting of the SIP peridotite formation and its relation to the evolution of the Caribbean Plate. Comparisons of spinel Cr no. (13–21), Mg no. (63.3–69.6) and TiO 2 suggest an abyssal peridotite origin; however, only Sierra Bermeja presents high TiO 2 characteristics of a mid-ocean-ridge … WebbOccurrence. Peridotite is the dominant rock of the upper part of Earth's mantle. It is obtained either in the form of solid blocks and fragments or crystals accumulated from magmas formed in the mantle..

WebbPeridotite is distributed widely across the globe because it is the dominant rock that composes the Earth’s crust. It is a layer that lies beneath a thin layer of other sediments. As the Earth’s crust shifts it may expose the underlying peridotite layer, but this layer is very unstable when exposed.
Webb17 sep. 2010 · To constrain the existence of melt at the base of the mantle, we performed melting experiments on a fertile peridotite composition over a range of lower-mantle pressures between 36 and 140 GPa using a laser-heated diamond-anvil cell (DAC) coupled with in situ synchrotron measurements ( 14 ). Our study thus extends the pressure range … Peridotite is the dominant rock of the Earth's mantle above a depth of about 400 km; below that depth, olivine is converted to the higher-pressure mineral wadsleyite. Oceanic plates consist of up to about 100 km of peridotite covered by a thin crust. The crust, commonly about 6 km thick, consists of basalt, gabbro, … Visa mer Peridotite is a dense, coarse-grained igneous rock consisting mostly of the silicate minerals olivine and pyroxene.
