Small-scale Sr and O isotope variations through the UG2 in the eastern Bushveld Complex: The role of crustal fluids

Autor: Chris Harris, Tawanda D. Manyeruke, Rolf L. Romer, Ilya V. Veksler, Mathias Schannor, Lutz Hecht

Publikováno v: Chemical Geology

A detailed study of the Sr- and O- isotopic composition of minerals in the Upper Group 2 (UG2) unit of the eastern Bushveld Complex revealed significant variations in the pegmatoidal footwall pyroxenite and the UG2 chromitite layer itself. Initial 87

Publikováno v: Chemical Geology. 481:95-109

In the Archean Quadrilatero Ferrifero district (SE Brazil), tourmaline occurs as a major constituent in a leucogranitic intrusion and numerous pegmatitic/aplitic veins within magmatic basement complexes, as well as in quartzo-feldspathic veins, in qu

Paleoproterozoic sources for Cordilleran-type Neoproterozoic granitoids from the Araçuaí orogen (SE Brazil): Constraints from Hf isotope zircon composition

Autor: Ariela Mazoz, Cristiano Lana, Kathryn Cutts, Mathias Schannor, Francesco Narduzzi, Marco Antônio Fonseca

Publikováno v: Lithos. :105815

The Aracuai orogen of SE Brazil exposes numerous amounts of magnesian, metaluminous, calc-alkaline, and medium- to high-K granitoid batholiths that were emplaced during early convergence between the Sao Francisco and Congo cratons during West Gondwan

Electrochemical Processes in a Crystal Mush: Cyclic Units in the Upper Critical Zone of the Bushveld Complex, South Africa

Autor: Lutz Hecht, Peter Dulski, Robert B. Trumbull, D. L. Reid, Mathias Schannor, Ilya V. Veksler, Jakob K. Keiding

Publikováno v: Journal of Petrology

The Upper Critical Zone (UCZ) of the Bushveld Igneous Complex displays spectacular layering in the form of cyclic units comprising a basal chromitite layer overlain by a sequence of silicate cumulates in the order, from bottom to top, pyroxenite–no

Lithos, 2018, 296, pp.1-16. ⟨10.1016/j.lithos.2017.10.017⟩

International audience; In the Phanerozoic, plate tectonic processes involve the fragmentation of the continental mass, extension and spreading of oceanic domains, subduction of the oceanic lithosphere and lateral shortening that culminate with conti
