Origin of the calc-alkaline igneous rock suite
Abstract A model is presented whereby the calc-alkaline series of igneous rocks is derived by partial melting of quartz eclogite at depths of approximately 100–140 km, leaving a residuum of clinopyroxene and garnet. Investigations of the fractional melting and crystallization of synthetic quartz tholeiite, basaltic andesite, andesite, dacite and ...

Model for the Origin and Significance of Microgranular Enclaves in Calc-alkaline Granitoids [PDF]
The origin and significance of microgranular enclaves as indicators of the occurrence of magma mixing and/or mingling episodes between basic magmas and anatectic acid magmas, either I- or S-type, are re-evaluated. A model for studying microgranular enclave and host rock associations has been developed, based on the geochemical characteristics and the ...

Geochemical evidence of dykes in the Salafchegan-Tafresh region as part of Cenozoic magmatism in the central segment of the Urumieh-Dokhtar magmatic arc [PDF]
IntroductionIran constitutes a critical segment of the Alpine-Himalayan orogenic belt, formed through the collision of the Arabian, Indian and Eurasian tectonic plates (Rolland et al., 2002; Stampfli and Hochard, 2009; von Raumer et al., 2003; Yin and ...

The Encantada Granite: registration of a peraluminous intrusion in the Rondonian Province - San Ignacio, in SW Amazonic Craton, Mato Grosso, Brazil [PDF]
The Encantada Granite occurs on the extreme southwest of the state of Mato Grosso, SW of the Amazonian Craton, near the border of Brasil/Bolívia. It corresponds to an body oriented to NNW direction that intruded metasedimentary and metavolcanic rocks ...

Archean Geodynamic Regimes of the Southeastern North China Craton: Insights from Petrological and Geochemical Constraints [PDF]
The nature and origin of Archean tectonic features that appear analogous to modern-style subduction remain insufficiently constrained. In this study, we investigated a variety of rock specimens from the southeastern margin of the North China Craton ...

Timing of the Granite magmatism, Wadi Abu Abid, North Eastern Desert, Egypt [PDF]
Granitic rocks represent a large portion of the Arabian-Nubian Shield (ANS) exposures in the North Eastern Desert (NED). The timing of the magmatic events plays a major role in illustrating the ANS development.

An Electrophilic Uridine Building Block for Post-Synthetic RNA Modification as Exemplified for Spin Labeling. [PDF]
An electrophilic 5‐isothiocyanatomethyl uridine building block enables modular post‐synthetic RNA labeling with primary amine‐containing probes. Positioning the functionality in the major groove minimizes structural perturbation and allows facile conjugation of sensitive tags such as TEMPO spin labels for paramagnetic relaxation enhancement studies ...
