Geology of East Greenland

Presented byJames Creswell Founder, Geo World Travel Over 80% of Greenland is covered by ice and, in places, this is up to 3.4km thick, so it might not immediately spring to mind as a place to go to observe rocks. However, it is a huge country and has an ice-free area of 410,000 sq km, which is generally sparsely vegetated, leaving the rocks beautifully exposed and the geology incredibly easy to see. The area of East Greenland around Scoresby Sund, Kong Oscar and Kejser Franz Joseph Fjords is the largest ice-free area in Greenland. It has incredible geodiversity, with basement rocks as old as three billion years, an almost complete sedimentary record of the last 1.6 byrs and huge volumes of flood basalts from the splitting of the Atlantic. This talk will take you on a virtual tour of the geological diversity of this fascinating and spectacular part of the world.
