One billion years of Archean history, Pilbara Craton, Western Australia

摘要

The Pilbara is an important region for the study of early Earth history, primarily because it contains large areas of volcanics and sediments, as old as 3550 million years, that are commonly extremely well preserved as a result of an exceptionally heterogeneous tectonic overprint during cratonisation. This latter event was completed by 2800 million years ago and hence much of the cover sequence up to the classic Hamersley banded iron formation is Archean in age.
