The recent years have seen progress in our understanding of the quantitative links between long-term Earth evolution as accommodated in the deep Earth and the evolution of the Earth’s surface systems including the ocean, atmosphere, and biosphere. This special collection consists of cutting-edge, provocative perspectives on a range of issues that have recently been tackled in this field. Those include the interactions between glacial cycles, volcanism, and climate; the link between long-term plate tectonic evolution, mantle structure, and eruption of large igneous provinces; the role of the mantle in controlling the geodynamo; feedbacks between weathering of continental and oceanic crust, tectonics, orogeny and the climate system; long term sea level variations, mantle convection, and climate; the interactions between the interior and the biosphere for the progressive rise of oxygen; and links between mantle convection and mass extinctions.

Slow slip is a new kind of fault slip behavior found predominantly on the boundaries between tectonic plates. In addition to geodetically-observed slow deformation, possible signatures of slow slip include several diverse phenomena often associated with slow slip including tremor, low-frequency earthquakes, and slowly-migrating triggered seismicity. This theme encompasses observational, theoretical, modelling, and laboratory studies focusing on any of these aspects of slow slip, or their implications for fault mechanics or earthquake hazard. The February 2016 Chapman Conference on Slow Slip Phenomena highlighted current understanding in the field and served as the catalyst for this collection. However, the call for papers includes other work that falls within the theme.
Call for Papers for “Wilson Cycles and the Formation of Marginal Basins: Rifting Dynamics and Mantle Evolution from Mid-ocean Ridge Creation to Extinction”
Submission deadline: 31 March 2018
Associate Editors: Anne Briais, Chun-Feng Li, Jian Lin, Anthony Koppers
Marginal basins develop at the frontier between continents and large oceans, or within oceanic plates, through the tearing of continental lithosphere or volcanic arc terrains. The forces acting on these smaller blocks moving apart are more complex than those driving the motion of the major plates. In these confined, miniature oceans, processes are different from those shaping the larger oceans, including lithospheric stretching, mantle melting, spreading inception and extinction, ridge dynamics, and sedimentary responses. The South China Sea is an excellent natural laboratory to study these processes, as it evolved at the boundary between three major plates: Eurasia, Pacific and India-Australia, and its spreading ridge is now extinct. It has witnessed surging interests in recent years, with extensive geophysical surveys and IODP expeditions. The first expedition of the International Ocean Discovery Program on South China Sea tectonics (IODP Expedition 349, 2014) targeted the oceanic crust and the continent-ocean transition zone of the South China Sea, successful coring through thick sedimentary cover to the basaltic basement. Two more IODP expeditions have already been scheduled, focusing exclusively on the continent-ocean transition zone (IODP Expeditions 367 and 368, 2017). These studies help address fundamental problems of continental breakup, mantle melting, oceanic lithosphere evolution, and terminal processes of seafloor spreading. Our goal is to better understand how marginal basins evolve within the larger Wilson Cycle and how the formation of those basins have responded to continental collision and active margin deformation. The G3 theme will integrate geological and geodynamic processes, before, during, and after the opening of marginal and back-arc basins around the world, for example the South China, Sulu and Andaman Seas, the Shikoku Basin and Mariana Trough, the Tyrrhenian Sea and Alboran Basin, and others. Manuscripts should be submitted through the GEMS website. For additional information please contact: email@example.com.
