Petrogenetic evolution of late Cenozoic, post-collision volcanism in western Anatolia, Turkey
TL;DR: The early stage of collision-related volcanism, which was most evident during the Early Miocene (<21 Ma), produced a considerable volume of lavas and pyroclastic deposits of basaltic andesite to rhyolite composition.
Journal ArticleDOI
Carbonatite metasomatism in the northern Tanzanian mantle: petrographic and geochemical characteristics
TL;DR: In this article, the authors used trace element signatures of carbonatite melts responsible for modal metasomatism of peridotite xenoliths from the Olmani cinder cone, northern Tanzania.

Petrogenesis of Adakitic Porphyries in an Extensional Tectonic Setting, Dexing, South China: Implications for the Genesis of Porphyry Copper Mineralization
Qiang Wang,Ji-Feng Xu,Ping Jian,Zhiwei Bao,Zhen-Huan Zhao,Chaofeng Li,Xiaolin Xiong,Jinlong Ma +7 more
TL;DR: The Dexing adakitic porphyries have a crystallization age of 171 ¼ 3 Ma, which is contemporaneous with Middle Jurassic extension within the Shi-Han rift zone, and within-plate magmatism elsewhere in South China, indicating that the Dexing porphyry were probably formed in an extensional tectonic regime in the interior of the continent rather than in an arc setting as mentioned in this paper.

Post-Collisional Potassic and Ultrapotassic Magmatism in SW Tibet: Geochemical and Sr–Nd–Pb–O Isotopic Constraints for Mantle Source Characteristics and Petrogenesis
TL;DR: In this paper, chemical data for post-collisional ultrapotassic, silicic, and high plateau of Tibet, the Himalaya and the Kapotassic and high-K calc-alkaline volcanic rocks from SW Tibet, rakoram Ranges are presented.
Journal ArticleDOI
High-potassium, calc-alkaline I-type plutonism in the European Variscides: northern Vosges (France) and northern Schwarzwald (Germany)
TL;DR: In this paper, the chemical and isotopic properties of early carboniferous high-K, calc-alkaline I-type plutonic rocks from the northern Vosges and Schwarzwald were studied for their chemical and Sr-Nd isotopic compositions.

Journal ArticleDOI
Determination of REE, Ba, Fe, Mg, Na and K in carbonaceous and ordinary chondrites
TL;DR: In this paper, the exact determination of REE and Ba abundances in three carbonaceous (Orgueil Cl, Murchison C2 and Allende C3) and seven olivine-bronzite chondrites were carried out by mass spectrometric isotope dilution technique.
Journal ArticleDOI
Rare-earth abundances in chondritic meteorites
TL;DR: In this article, 15 chondrites, including eight carbonaceous chondites, were analyzed for rare earth element abundances by isotope dilution, and the persistence of anomalies in chondritic materials relatively removed from direct condensational processes implies that anomalous components were introduced at a late stage of chondrite formation.
Journal ArticleDOI
A chemical-petrologic classification for the chondritic meteorites.
W. R. Van Schmus,John A. Wood +1 more
TL;DR: In this article, a two-dimensional classification grid based on chemical and petrologic subdivisions of chondritic meteorites is proposed, which extends the current chemical subdivisions to account for varying petrolic (implied metamorphic) properties within the primary chemical groups.
Journal ArticleDOI
Condensation in the primitive solar nebula
TL;DR: In this article, the distribution of the major elements between vapor and solid has been calculated for a cooling gas of cosmic composition, assuming that high temperature condensates remain in equilibrium with the vapor, affecting the temperatures of appearance of successively less refractory phases.
