A review of detrital heavy mineral contributions to furthering our understanding of continental crust formation and evolution

Autor: Inês Pereira, Valby van Schijndel, Mahyra Tedeschi, Kathryn Cutts, Martin Guitreau

Publikováno v: Geological Society, London, Special Publications. 537

Detrital heavy minerals have helped address geologically complex issues such as the nature and origin of the early terrestrial crust, the growth and evolution of the continental crust, as well as the onset of plate tectonics, together with paleogeogr

Current applications using key mineral phases in igneous and metamorphic geology: perspectives for the future

Autor: Silvia Volante, Eleanore Blereau, Martin Guitreau, Mahyra Tedeschi, Valby van Schijndel, Kathryn Cutts

Publikováno v: Geological Society, London, Special Publications. 537

The study of magmatic and metamorphic processes is challenged by geological complexities like geochemical variations, geochronological uncertainties and the presence/absence of fluids and/or melts. However, by integrating petrographic and microstruct

De Kraalen and Witrivier Greenstone Belts, Kaapvaal Craton, South Africa: Characterisation of the Palaeo-Mesoarchaean evolution by rutile and zircon U-Pb geochronology combined with Hf isotopes

Autor: Dirk Frei, Cristiano Lana, Gary Stevens, Valby van Schijndel, Thomas Zack

Publikováno v: South African Journal of Geology. 124:17-36

The formation and evolution of Palaeoarchaean De Kraalen and Witrivier Greenstone Belts (DKGB and WGB) of the Kaapvaal Craton are poorly known. Here we report zircon and rutile in situ U-Pb ages and zircon Hf isotopic data from a variety of supracrus

Reply to comment by S.H. Büttner on 'Evidence for Mesoproterozoic collision, deep burial and rapid exhumation of garbenschiefer in the Namaqua Front, South Africa ˮ

Autor: David H. Cornell, Robert Anczkiewicz, Valby van Schijndel, Anders Scherstén

Publikováno v: Geoscience Frontiers, Vol 11, Iss 5, Pp 1895-1899 (2020)

We thank Prof. Buttner for his comments on our paper (van Schijndel et al., 2020), which allow us to clarify our work and the tectonic model we proposed for the eastern margin of the Namaqua Sector of the Namaqua Natal Metamorphic Province. The Kaaie

Evidence for Mesoproterozoic collision, deep burial and rapid exhumation of garbenschiefer in the Namaqua Front, South Africa

Autor: Robert Anczkiewicz, Valby van Schijndel, Anders Scherstén, David H. Cornell

Publikováno v: Geoscience Frontiers, Vol 11, Iss 2, Pp 511-531 (2020)

Metamorphic provinces such as the ∼1 Ga Grenvillian, ∼400 Ma Caledonide and Triassic Qinling Provinces often contain rocks with high-pressure assemblages such as eclogites, which formed at mantle depths in subduction zones. These are eviden

Evidence of Jurassic extension in NW Argentina: Characterization of fault-related strata at the Salta Group base using sandstone provenance and zircon U–Pb geochronology

Autor: Willemijn S.M.T. van Kooten, Cecilia E. Del Papa, Daniel Starck, Edward R. Sobel, Pablo Cavalleri, Maximiliano Agüera, Valby van Schijndel, Johannes Glodny

Publikováno v: Journal of South American Earth Sciences

The present-day structure of the Eastern Cordillera in NW Argentina is governed by structural and lithological heterogeneities inherited from preceding deformation phases, which influence the localization of newly-formed faults and the inversion of p

In situ U-Pb geochronology on garnet and rutile: New age data from the Palaeoarchaean Onverwacht Group, Barberton Greenstone Belt, South Africa

Autor: Valby van Schijndel, Thomas Zack, Gary Stevens, Cristiano Lana, Kathryn Cutts

The Barberton Greenstone Belt (BGB) is a well-preserved remnant of Paleo- to Mesoarchean crust. The oldest supracrustal rocks of the BGB consist of the 3.5-3.3 Ga Onverwacht Group. These rocks form a NE-SW trending belt deformed and metamorphosed lar

Timing of exhumation of meta-ophiolite units in the Western Alps: New tectonic implications from 40Ar/39Ar white mica ages from Piedmont Zone (Susa Valley)

Autor: Marco Gattiglio, Gianni Balestro, Alessandro Borghi, Stefano Ghignone, Valby van Schijndel, Silvio Ferrero, Masafumi Sudo

Publikováno v: Lithos. :106443

A multidisciplinary approach to the study of collisional orogenic belts can improve our knowledge of their geodynamic evolution and may suggest new tectonic models, especially for (U)HP rocks inside the accretionary wedge. In the Western Alps, wherei
