Abstract To characterize the integrated magmatic processes for magma plumbing systems from mantle sources to chambers, we present Mg–Sr–Nd isotopic data a representative mafic–ultramafic intrusion in Xiarihamu, northern Tibetan Plateau, China. The hosts largest Ni–Cu sulfide deposit an orogenic setting world and is composed predominantly of harzburgite, orthopyroxenite, websterite, gabbronorite...

introduction the area reviewed and studied in this paper is located 5 km southeast of sarbisheh city at eastern border of the lut block (jung et al., 1983; karimpour et al., 2011; richards et al., 2012) in eastern iran between 59° 47′ and 59° 53′ e longitude and 32°30′ and 32°34′ n latitude. the magmatic activity in the lut block began in middle jurassic (165-162 ma) and reached its peak in ter...

The North China Craton (NCC) experienced strong destruction (i.e., decratonization) during the Mesozoic, which triggered intensive magmatism, tectonism and thermal events formed large-scale gold other metal deposits in eastern part of craton. However, how decratonization controls formation distribution is not very clear. Based on a large number published data new results, this paper systematica...

The Spontang Ophiolite complex represents the most complete ophiolite sequence amongst South Ladakh ophiolites and comprises mantle rocks (depleted harzburgites, dunites minor lherzolites) as well crustal (basalt, isotropic gabbros, layered gabbros etc.). In present study, detailed geochemistry (whole rock mineral chemistry) Sr-Nd isotopic analyses of thirty-six ultramafic- mafic samples have b...

Abstract The petrogenesis and evolution process of continental arc magmatism provide insight into discovering the formation differentiation crust. Therefore, geochemical, isotopic, mineralogical analyses were conducted for coeval igneous rocks in Tengchong Block to clarify their magmatic systems. Middle Triassic appinites Block, southeastern extension Tibet, generated at subduction setting with...

Mantle cell lymphoma is an aggressive type of B-cell non-Hodgkin's lymphoma that originates from small to medium sized lymphocytes located in the mantle zone of the lymph node. The gastrointestinal tract is the predominant site of extranodal involvement in the form of multiple lymphomatous polyposis. Multiple lymphomatous polyposis due to mantle cell lymphoma presenting with intussusception is ...

The South Armenian Block (SAB) belongs to the Lesser Caucasus, and it is located where Central Tethyan belt bends from an EW orientation in Turkey NW-oriented Iranian tectonic zones. Magmatism these belts result of convergence, collision post-collision evolution Arabian plate with Eurasian margin. An exhaustive study including whole-rock major, trace element, radiogenic isotope (Sr, Nd, Pb) dat...

Clustering of arc volcanoes in subduction zones indicates along-arc variation in the physical condition of the underlying mantle where majority of arc magmas are generated. The sub-arc mantle is brought in from the back-arc largely by slab-driven mantle wedge flow. Dynamic processes in the back-arc, such as small-scale mantle convection, are likely to cause lateral variations in the back-arc ma...

To improve the understanding of formation and evolution sub-continental lithospheric mantle (SCLM) underlying South Australian Craton we have conducted a detailed petrological study on >3,000 xenocrysts from 13 kimberlites emplaced across craton. Pressure (P) temperature (T) estimates Cr diopside garnet been coupled with their chemical concentrations to constrain thickness chemo-lithostratigrap...
