|Understanding circum-Arctic tectonics: A Eurasian perspective|
Stockholm University, Sweden
Renewed interest in the Arctic region due to, for example, the United Nations Law of the Sea (UNCLOS) Article 76, the International Polar Year (IPY), and the high price of oil, has in recent years motivated new field studies and sampling programs. These in turn have led to a better understanding of the tectonic development of some parts of the circum-Arctic region. However, little progress has been made in other regions. For example, our understanding of the tectonic development of the Canada Basin in the Arctic Ocean remains as poorly understood and as highly debated today as it was in 1995 when a GSA Penrose Conference was held to specifically address its tectonic development!
In this Keynote, I will i) highlight advances in our understanding the geologic development and tectonic evolution of the Arctic from the last 10 years or so of Eurasian land-based investigations, ii) identify problem areas which hinder a full understanding of the geologic development and tectonic evolution of the Arctic, and iii) suggest avenues of future research which are likely to be fruitful for making real inroads to resolving some of these uncertainties.
