Journal ArticleDOI
Tectonic setting of kimberlites
TL;DR: Kimberlite ages span the assembly and break-up of a number of supercontinents, such as Rodinia and Gondwana as mentioned in this paper, and their distribution illustrates clustering in time and space.
Journal ArticleDOI
Preferential distribution along transcontinental corridors of kimberlites and related rocks of Southern Africa
Hielke Jelsma,Maarten J. de Wit,Christien Thiart,Paul H.G.M. Dirks,Giulio Viola,I.J. Basson,Eva Anckar +6 more
TL;DR: In this paper, the emplacement of kimberlites and related rocks in Southern Africa is analyzed using a framework of lineaments defined by combining geology, aeromagnetics, gravity and geomorphological data.
Journal ArticleDOI
Electrical lithosphere beneath the Kaapvaal craton, southern Africa
Rob L. Evans,Alan G. Jones,Xavier Garcia,Mark R. Muller,Mark P. Hamilton,Mark P. Hamilton,S. F. Evans,C. J. S. Fourie,J. Spratt,J. Spratt,Susan J. Webb,Hielke Jelsma,David A. Hutchins +12 more
TL;DR: The Southern African Magnetotelluric Experiment (SAMTEX) has revealed complex structure in the lithospheric mantle of the southern African Kaapvaal craton and surrounding terranes as discussed by the authors.
Journal ArticleDOI
Lithospheric structure, evolution and diamond prospectivity of the Rehoboth Terrane and western Kaapvaal Craton, southern Africa: Constraints from broadband magnetotellurics
Mark R. Muller,Alan G. Jones,Rob L. Evans,Herman Grütter,C. Hatton,Xavier Garcia,Mark P. Hamilton,M. P. Miensopust,P. Cole,T. Ngwisanyi,D. Hutchins,C.J.S. Fourie,Hielke Jelsma,S. F. Evans,Theo Aravanis,W. Pettit,Susan J. Webb,Jan Wasborg +17 more
TL;DR: In this paper, a 2D magnetotelluric (MT) profile of the southern African lithosphere was used to estimate the present-day average lithospheric thickness to a precision of about 20 km.
Journal ArticleDOI
Constraints on Archaean crustal evolution of the Zimbabwe craton: a U-Pb zircon, Sm-Nd and Pb-Pb whole-rock isotope study
TL;DR: In this paper, the U-Pb ages of zircons from seven felsic volcanic and plutonic rocks from northern Zimbabwe combined with field data and isotope and geochemical data, constrain the timespan of development of the Harare-Shamva granite-greenstone terrain and establish the relative involvement of juvenile mantle-derived and reworked crustal material.
