Introduction: The shergottite meteorites have been subdivided into three groups based on texture and mineralogy [1]. EETA79001 is a shergottite that contains examples of all three lithologies: lherzolitic (lithology X), olivine-phyric (lithology A), and basaltic (lithology B). Therefore, studying the magmas involved in the petrogenesis of EETA79001 may provide information not only on its own pe...
Cretaceous kimberlites in southern Africa have been suggested to host deeply subducted material their mantle sources based on radiogenic isotope systematics. However, potential contributions the volatile budget, including sulfur, of these is unclear. Here we report new petrographic, geochemical, and isotopic data sulfides sulfates sub-volcanic from Kimberley, South Africa. The examined were div...
