Magmatism at the Southern End of the East African Rift System: Origin and Role During Early Stage Melting
Samples collected throughout the Rungwe Volcanic Province, southwest Tanzania, East African Rift. Sample set consists primarily of unaltered, primary volcanics, emphasizing the mafic compositions with GPS-recorded locations. Other samples include intermediate and felsic compositions. Analytical dataset consists of major element concentrations measured by ICP-OES, trace element concentrations measured by quadrupole ICP-MS, and isotopic Sr-Nd-Pb-Hf ratios measured by MC-ICP-MS on whole rock powders. Subset of the data have been dated with Ar-Ar geochronology yield Miocene-Quaternary ages for Rungwe Volcanic Province, and Jurassic ages for carbonatites.
