Orthopyroxene is the second most abundant mineral in upper mantle and, like olivine, can form crystallographic preferred orientations (CPO) during deformation that may influence seismic anisotropy. Here we use a compilation of 21 peridotites which both olivine and orthopyroxene CPOs are preserved to document range CPO types explore their effects on anisotropy peridotites. In addition four previ...

Post-orogenic extension in back-arc regions is classically associated with metamorphic core complexes (MCCs) cored exhumed rocks and granitic intrusions interacting low-angle detachments. When additional heat provided by the advected asthenosphere below extending region, for instance above slab tears, high-temperature migmatite-cored domes composite are emplaced whose geometry kinematics of emp...

The Canadian Superior Province has become one of the key test pieces to discuss tectonic processes and mechanisms crustal growth in Late Archean. consists a >2.8 Ga proto-cratonic core intruded by voluminous arc-like plutons surrounded series narrow, elongate ca. 2.8–2.7 juvenile belts, also referred as terranes or domains. seem wrap around generally young outward, but kinematics geodynamic cau...

The present study explores the characteristics of 2D MHD melting with reference to mass and heat transportation upon stagnation point Powell–Eyring nanofluid flow on an extensible surface. Melting is important phenomenon that involved in many procedures such as permafrost melting, solidification slag, defrosting frozen ground etc., all which are examples soil freezing involve trafficking throug...

Pre-mRNA splicing further increases protein diversity acquired through evolution. The underlying driving forces for this phenomenon are unknown, especially in terms of gene expression. A rice alternatively spliced transcript detection microarray (ASDM) and RNA sequencing (RNA-Seq) were applied to differentiate the transcriptome of 4 representative organs of Oryza sativa L. cv. Ilmi: leaves, roo...

The fault geometry, depth, and slip distribution of the Kurile earthquake of Oct. 4, 1994 are estimated using seismic waveforms, aftershock distribution, geodetic measurements, and tsunami waveforms. Previous large earthquakes in the Kurile arc had typical underthrusting focal mechanisms due to the local subduction. Seismic wave inversions of the 1994 event indicate a thrust type mechanism with...

Abstract Anisotropy of magnetic susceptibility can provide insights into strain distribution in models simulating fold-and-thrust belts. Models with layers sand and magnetite mixture shortened above adjacent decollements high low friction, are used to study the effect decollement friction on fabric. Above high-friction decollement, an imbricate stack produced a ‘tectonic’ fabric foliation paral...

At the Willendorf site Upper Paleolithic archeological layers associated to early Aurignacian cultures were found. The environmental conditions of society, potentially co-existing with Neanderthal groups, is still not fully understood. Here, we report on magnetic analyses including anisotropy susceptibility (AMS) carried out loessic aeolian sediments at site. Data lineation, foliation and degre...
