Can Archean granulites be direct crystallization products from a sialic magma layer
Jan Kramers,J. R. Ridley +1 more
TL;DR: In this article, an open-system fractional crystallization model for formation of TTG crust through solidification from a shallow-level tonalitic magma ocean is proposed. But this model assumes that the base of a thick convecting magma layer will be undersaturated with respect to H 2 O and CO 2.
Book ChapterDOI
Intracrustal radioactivity as an important heat source for Neoarchean metamorphism in the Central Zone of the Limpopo Complex
Journal ArticleDOI
Sub-orbital sea-level change in early MIS 5e: New evidence from the Gulf of Corinth Greece
TL;DR: Siddall et al. as mentioned in this paper used uplifted marine isotope stage (MIS 5e) carbonate deposits in the Gulf of Corinth to demonstrate two rapid, sub-orbitally forced, sea-level oscillations in the early part of MIS 5e.
Journal ArticleDOI
A Mid-Pleistocene in situ fossil brown hyaena (Parahyaena brunnea) latrine from Gladysvale Cave, South Africa
Lee R. Berger,Robyn Pickering,Brian F. Kuhn,Lucinda Backwell,Phillip J. Hancox,Jan Kramers,Pedro Boshoff +6 more
TL;DR: An in situ fossil latrine is reported from Gladysvale Cave, South Africa as mentioned in this paper, which indicates that troglodytic latrine-making behaviour in P. brunnea may be traced to at least the Late Middle Pleistocene of southern Africa.
Journal ArticleDOI
Effects of long soil surface residence times on apparent cosmogenic nuclide denudation rates and burial ages in the Cradle of Humankind, South Africa
Tebogo V. Makhubela,Jan Kramers,Dirk Scherler,Dirk Scherler,Hella Wittmann,Paul H.G.M. Dirks,Paul H.G.M. Dirks,Stephan R. Winkler +7 more
TL;DR: In this article, the authors used cosmogenic 10-Beryllium (Be-10) in river sediments to estimate denudation rates and the ratio of 26-Aluminium (Al-26) to Be-10 (Al26/Be10), to constrain ages of sediment burial.
