[1] We studied the back azimuth dependence of Ps converted phases at GSN station COR (Corvallis, Oregon) using broadband P receiver functions computed from 602 teleseismic earthquakes. The amplitudes and polarities of the transverse Ps phases are largely two-lobed, which indicates anisotropy with a tilted symmetry axis. A double-peaked Ps conversion at 4.5–6.5 s delay has the moveout of a dippi...

Based on the analysis of gravitational and magnetic anomalies eastern part East European Platform, it is concluded that inhomogeneities caused by serpentinization processes are present in Earth’s crust. This conclusion confirmed conducting geological geophysical studies reference objects with serpentinite outcrops.

Occurrences of diopsidites, rocks made predominantly gem-like diopside whose composition precludes a purely igneous origin, allow tracking the pathway high-temperature fluids and fluid-saturated melts in oceanic lithosphere vicinity mantle-crust transition zone (the Moho) adjacent mantle an setting. We have experimentally explored origin diopsidites by reacting serpentinite with synthetic haplo...

The exposure of Mesozoic rocks in the Mangilu area, both as a result tectonic deformation form mélange, low-high degree metamorphism and deep-sea sediments (flysch, radiolarian cherts, sediment flow olistostrome), which formed subduction zone indicates complex accretionary rocks. purpose this study is to identify trace era. method used was field observation, including collection geological data...

Serpentinite is a low-grade metamorphic rock derived from the transformation of ultramafic rocks. Mainly because its aesthetic characteristics it has been widely used as building and ornamental stone. “Verde di Prato” most common local name in Tuscany to refer this type rock, historically quarried area for many centuries large number monuments region. In paper, we report results study carried o...

Mineral paragenesis of rodingitized basic rocks of Iranian ophiolites are presented and metasomatic reactions between Ca+2 bearing aqueous fluids issued during serpentinization of host ultramafic rock – with magmatic minerals of basic rocks leading to present paragenesis of rodingites are discussed. It is concluded that Ca+2 rich aqueous fluid in equilibrium with serpentinite has high Ca+2 chem...
