Model for the Origin and Significance of Microgranular Enclaves in Calc-alkaline Granitoids [PDF]
Journal of Petrology, 1991 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 ...

Archean Geodynamic Regimes of the Southeastern North China Craton: Insights from Petrological and Geochemical Constraints [PDF]
LithosphereThe 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 ...

Angewandte Chemie, EarlyView.The luminescence of a heterometallic d‐s {Cu2I2Na2} phosphane‐phosphinate aggregate is regulated by an interplay of Na+–π/I– contacts and reversible coordination of oxygen‐containing organic molecules to Na ions. Structural variations caused by the incoming guest lead to a wide and selective variation of the emission color and illustrate a new approach

Timing of the Granite magmatism, Wadi Abu Abid, North Eastern Desert, Egypt [PDF]
Alfarama Journal of Basic & Applied SciencesGranitic 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.
