Why Iceland?

The life of a graduate student has predominately been classwork (as a student as well as a teacher), but now I finally get to do what I have wanted to do since I got into geology years ago. I will be doing field work in Iceland for 5 weeks. The field work is a part of my Master's thesis, in which I am trying to determine, as most geologists in Iceland do, the origin of many of the volcanic rocks. Iceland sits on a portion of the Earth's crust in which volcanism is favored for multiple reasons. First, the Earth's plates are being pulled apart here, this phenomenon makes for a prime location for volcanic activity on its own. In addition to the plate movement however, the mantle under Iceland is anomalously active causing even more volcanism than in a normal rift setting. These circumstances have drawn volcanologists and other geologists to the island for decades; now, with the help of my advisor, Sheila Seaman, and my great friend and field assistant, Brianna Force, I hope to add my small piece to the geologic puzzle that is Iceland. Work will consist of mapping and collecting of rock samples. A key goal that I have made for myself is to be able to identify individual lava flows within the complex; this will require very meticulous mapping.

The field area is in North-Central Iceland, just to the southwest of the city of Akureyri. It is an 8-9 million year old volcanic complex that spans a region roughly 35 km by 20 km and has been dissected by past glacial growth and movement.

  1. Unlike the rift, nice to see that this page is finally active. Iceland is my dream and this sounds impressive but what is your mapping trying to prove???
