Foreword to the special volume on 'Field, analytical and experimental approaches to silicic magmatism in collisional orogens'
Jul 01, 2008; ... Despite more than two hundred years of vigorous scientific interest, granite plutons are still in fashion and their origin continues to be hotly debated. This special issue of the Journal of Geosciences is intended to be a modest contribution to the recent granite debate by collecting ...
Death of super-continents and birth of oceans heralded by discrete A-type granite igneous events: the case of the Variscan-Alpine Europe
Jul 01, 2008; ... Granitoids occupy large areas of the Variscan-Alpine Europe. The specific group of A-type granites identifies postcollisional (post-orogenic) and anorogenic geodynamic settings. Post-orogenic igneous provinces are emplaced during the very last episodes of supercontinent amalgamation. Anorogenic ...
Formation of tabular plutons - results and implications of centrifuge modelling
Jul 01, 2008; ... Geophysical investigations reveal that many granitoid plutons possess a tabular shape: either laccolithic, lopolithic or phacolithic. In this study, the results of a centrifuge experiment are used to understand the formation mechanisms of these features. The model was build of a sequence of 14 ...
The Brno Batholith: an insight into the magmatic and metamorphic evolution of the Cadomian Brunovistulian Unit, eastern margin of the Bohemian Massif
Jul 01, 2008; ... The Brno Batholith, a part of the larger Brunovistulian Unit, consists of three genetically independent complexes - Western Granitoid Complex (part of the Thaya Terrane), Ophiolite Belt (formerly Metabasite Zone or Central Basic Belt), and Eastern Granitoid Complex (part of the Slavkov Terrane) ....
Geochemical and isotopic (Sr, Nd and O) constraints on sources of Variscan granites in the Western Carpathians - implications for crustal structure and tectonics
Jul 01, 2008; ... A Sr, Nd, and O isotopic study of Variscan granitoid rocks from the Western Carpathians reveals the dominance of heterogeneous crustal sources for the most of the granitic rocks. Their neodymium crustal index (NCI) is 0.4 to 1.0 (mainly 0.6-0.8). Initial (^sup 87^Sr/^sup 86^Sr)^sub 350^ of ...
Accessory columbite to tantalite, tapiolite and zircon: products of extreme fractionation in highly peraluminous pegmatitic granite from the Povazský Inovec Mountains, Western Carpathians, Slovakia
Jul 01, 2008; ... Accessory Fe-rich columbite-group minerals, tapiolite and Hf-rich zircon occur in Hercynian pegmatitic leucogranite near Duchonka, Povazský Inovec Mts., western Slovakia. The host rock represents highly peraluminous and fractionated S-type pegmatitic leucogranite with ASI = 1.27, Eu^sub ...
Geochemical and structural constraints on the magmatic history of the Chandman Massif of the eastern Mongolian Altay Range, SW Mongolia
Jul 01, 2008; ... In the Mongolian Altay range, immediately south of the Bogd fault zone, the Chandman Massif intruded the Chandman Khayrkhan Crystalline Complex to the NE. This complex consists of migmatized biotite gneisses, orthogneisses and amphibolites. To the south, the Massif cuts the chlorite schists and ...
Contrasting crustal sources for peraluminous granites of the segmented Montes de Toledo Batholith (Iberian Variscan Belt)
Jul 01, 2008; ... The Variscan Montes de Toledo Batholith (MTB) is an E-W linear array of peraluminous granite plutons which is chemically segmented. The study is focused on the western segment of the MTB (W-MTB), mainly composed of granites with slightly lower CaO and higher P^sub 2^O^sub 5^ contents than ...
