Talk - Petrogenesis of Cr-enriched chromites from Prince Mine, Mashava Igneous Complex - Jeff Chaumba

On Friday 1st June 2018, 2016 Jeff Chaumba, a graduate of University of Zimbabwe and now with the University of North Carolina at Pembroke, gave a talk entitled:-

'Petrogenesis of Cr-enriched chromites from Prince Mine, Mashava Igneous Complex'

The talk centred on results of microprobe anlayses of a series of chromitite samples collected in 1969 on a trip led by Jim Wilson and stored in the USA since then. Jeff's data suggest a convergent margin boundary rather than a layered mafic intrusion origin for the Mashava Igneous Complex.
