Catastrophic Perturbations to Earth's Deep Carbon Cycle

Table of Contents
Carbon is one of the most important elements on Earth. It is the basis of all life on the planet, is stored and mobilized throughout the Earth from core to crust, and is the basis of the energy sources that are so important to human civilization. This issue will explore the origins of carbon on Earth; the long-term carbon cycle; catastrophic and large-scale perturbations to Earth’s carbon cycle such as large igneous provinces and bolide impacts; carbon’s role in mass extinctions; and icehouse–greenhouse climate transitions in deep time. Deciphering the complex, and often faint, signals of distant carbon catastrophes requires a multidisciplinary effort and the most innovative analytical technology. This thematic collection comes at an important time in which carbon fluxes on Earth are changing rapidly. Society must understand the way in which the deep carbon cycle on Earth works to secure a sustainable future.

Volume 15, Number 6 (December) • Kimberlites From Deep Earth To Diamond Mines
GUEST EDITORS: Andrea Giuliani (University of Melbourne, Macquarie University, Australia) and D. Graham Pearson (University of Alberta, Canada)
Kimberlites are the most deeply derived of all volcanic rocks, as well as the host rock for most of the world’s diamond mines. Kimberlites, therefore, provide unique snap-shots of magma genesis and mantle evolution in the deep Earth well into the diamond stability field (>150 km and, potentially, >700 km). Despite over 100 years of study, the origin of this complex rock-type remains the subject of intense debate. This thematic issue will summarize current knowledge and controversies on kimberlite formation, including key aspects of the petrology, geochemistry and volcanology of these unique rocks. It will show how kimberlites can be successfully dated, and explore links between the temporal and spatial distribution of kimberlites and known geological events. Diamond exploration and resource evaluation methods will be reviewed to demonstrate the inextricable link between an accurate understanding of the characteristics of kimberlites, their entrained mantle cargo, and diamonds.
