Natasha Barrett PhD| DERTS Trainees

Natasha defended her PhD on December 8, 2020.

Natasha's research investigated the processes and evolution of the sub-oceanic lithospheric mantle beneath the Southwest (SW) Pacific region via two direct sampling methods: 1) basalt-hosted peridotite xenoliths erupted by volcanic eruptions from Koro Island in eastern Fiji, and 2) tectonically exposed sections of mantle lithosphere as ophiolite peridotites from the Marum ophiolite and Papuan Ultramafic Belt (PUB) in Papua New Guinea (PNG). Her study area was in the SW Pacific region that formed via complex tectonic interactions between the Pacific and Indo-Australian plate, and collectively, provide information on the melt depletion and subsequent melt enrichment history of the underlying mantle lithosphere of this vast region. 

Natasha completed a postdoctoral placement at the University of Copenhagen and subsequently moved on to a postdoctoral placement with the Mineral Deposits Resech Unit (MDRU)at the Univervity of British Columbia.
