This paper presents results of modelling reaction between peridotite and fractionating tholeiitic basalt in simple and complex silicate systems. Reactions are outlined in appropriate binary and ternary silicate systems. In these simple systems, the result of reactions between 'basalt' and 'peridotite' may be treated as a combination of Fe-Mg exchange and mass transfer reactions at constant Fe/M...

Based on chemical composition and timing of late Paleogene Neogene igneous rocks in southern Patagonia, six suites are identified correlated with subduction processes during the approaching active oceanic ridges. magmatism took place after a period decreased sub-alkaline (LPg Suite). Early Miocene calc-alkaline mark reactivation acceleration (Suite 1). These located at ca. 200 km from trench ty...

We report the first results of relativistic correlation calculation of the spectroscopic properties for the ground state of E112H and its cation in which spin-orbit interaction is taken into account non-perturbatively. Studying the properties of E112 (eka-Hg) is required for chemical identification of its long-lived isotope, (283)112. It is shown that appropriate accounting for spin-orbit effec...

This study was designed to evaluate the healing of the defect of compact bone tissue after implantation of osteoplastic material Calc-i-oss with the definition of the dynamics of its resorption and ® morphological characteristics of the components of the regenerate. In the middle third of the femoral shaft of Wistar rats we reproduced perforated defect to the medullary canal, which was filled w...

Amphibole (Amp) plays a crucial role in the study of several earth and planetary processes. One its most common applications is thermobarometry, especially for volcanic-magmatic systems. However, many thermobarometers require input melt composition, which not always available volcanic products (e.g., partially crystallized melts or devitrified glasses), show rather high errors characterizing de...

Post-collisional mafic dykes crosscut the Paleozoic metamorphic basement and late-Variscan plutons in Les Guilleries massif (Catalan Coastal Ranges, NE Iberia). The predominance of phenocrysts, porphyritic texture, abundant amphibole, high MgO volatile content, together with crustal-like trace-element patterns indicate that correspond to calc-alkaline lamprophyres, mainly spessartites. Their en...

Magmatic differentiation produces positive correlations between δ49Ti and SiO2. The equilibrium Ti isotope fractionation factors of Ti-bearing minerals are essential for understanding the mechanisms driving this isotopic fractionation. We present ab initio-derived mean force constants (barium orthotitanate, potassium titanium oxide, fresnoite, diopside, geikielite, karrooite, titanite, pseudobr...
