Reading the Archive of Earth s Oxygenation

This is the first of three volumes that survey the Palaeoproterozoic Eon with a focus on Fennoscandian Shield geology, reviewing early Palaeoproterozoic events coincident with Earth's progressive oxygenation. Includes photos of the FAR-DEEP core collection.

Earth's present-day environments are the outcome of a 4.5 billion year period of evolution reflecting the interaction of global-scale geological and biological processes punctuated by several extraordinary events and episodes that perturbed the entire Earth system. One of the earliest and arguably greatest of these events was a substantial increase (orders of magnitude) in the atmospheric oxygen abundance, sometimes referred to as the Great Oxidation Event.
Volume 1: The Palaeoproterozoic of Fennoscandia as Context for the Fennoscandian Arctic Russia - Drilling Earth Project describes the implementation of the FAR-DEEP drilling project in Arctic Russia. It summarises the knowledge of more than 50 years of largely Russian-led fieldwork, information hitherto virtually unavailable in the west, and provides geological description of drilling areas with an overwhelming illustration of rocks by high-quality, representative photographs. The volume offers a comprehensive review and rich photo-illustration of palaeotectonic, palaeogeographic and magmatic evolution of the Fennoscandian Shield in the early Palaeoproterozoic, and link the evolution of the shield to the emergence of an aerobic Earth system. The volume unfolds the event-based Fennoscandian chronostratigraphy and discusses the chronology of the Palaeoproterozoic global events as the base for a new subdivision of Palaeoproterozoic time.
Welcome to the illustrative journey through one of the most exciting periods of planet Earth!

Establishment of a well-characterized, well-dated and well-archived succession of rocks for the period of 2500-2000 Ma Documentation of the changes in the biosphere and the geosphere associated with the rise in atmospheric oxygen Development of a self-consistent model to explain the genesis and timing of the establishment of the aerobic Earth System Includes supplementary material: sn.pub/extras
