Icelandic Continental Analogue for Sialic Evolution

Study of granitoids on Iceland to see if they could be analogues for early Earth granotoids.

Earth's early crust (before 4 billion years ago) was thought to be largely made of rocks similar to those that make up the present day ocean floor. However, some think that evidence for some rocks that resemble those foming today's continents means that this is not the case. Iceland may help to resolve this argument since it is formed from rocks within the middle of the Atlantic Ocean, very far form continents, but contains some "continental-like" rocks. This project will assess how these rocks formed and whether they could be analogues of similar rocks formed in the early Earth.
