Title:
Magmatism at the Southern End of the East African Rift System: Origin and Role During Early Stage Melting
Creator(s):
  • Mesko, Gary
Abstract:
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.
