MARZ - Magmatism in the Africa-Antarctica Rift Zone

MARZ project studies the origins and evolution of the largest lava eruptions on Earth. Our research concentrates especially on African and Antarctic continental flood basalt formations that erupted during the initial stages of the break up of the Gondwana supercontinent in Jurassic times ~180 million years ago, during the golden age of the dinosaurs.

The project is funded for 2012–2015 by the Academy of Finland (project number 252652). The Finnish team consists of the principal investigator and senior curator Arto Luttinen and postdoctoral researchers Jussi Heinonen and Matti Kurhila. In addition, the project involves BSc students Sanni Turunen and Riina Puttonen, who are studying recently collected samples from Africa for their Master's Theses. Our most important collaborators are Carnegie Institution of Washington, Woods Hole Oceanographic Institution, British Antarctic Survey, University of Cape Town, Eduardo Mondlane University, and Geological Survey of Finland.
