Next IRIS Webinar 02/12 – Imaging the African Superplume Using AfricaArray Data

Posted on by

The next IRIS Webinar highlights “Imaging the African Superplume Using AfricaArray Data: Is the Superplume a Whole-Mantle Structure?” at 2 pm EST (7 pm UTC) on Wednesday, 2/12.

Register to attend: https://www2.gotomeeting.com/register/617775338

You will be emailed a confirmation containing a link for accessing the webinar. The presentation and subsequent interactions between the speaker, host, and audience are recorded and made available within a few days. Access to the webinar archive, along with related materials and more information on the series is found here: http://www.iris.edu/hq/webinar/

Presenter: Professor Andy Nyblade, Pennsylvania State University

Abstract: The African superplume is arguably one of the largest features in Earth’s lower mantle and whether or not it extends into the upper mantle beneath eastern Africa, giving rise to the Cenozoic rifting, volcanism and plateau uplift found there, has long been debated. New seismic images of mantle structure obtained from modeling AfricaArray data indicate that the superplume is indeed a whole-mantle structure. The images come from body and surface wave tomography, receiver function stacks illuminating topography on the 410 and 660 km discontinuities, and shear wave splitting. The seismic images are consistent with a thermal anomaly of a few hundred degrees spanning the mid-mantle connecting anomalous lower mantle structure under southern Africa with anomalous upper mantle structure under eastern Africa.

Finalized ExTerra white paper now available

Posted on by

Dear ExTerra friends,

The finalized ExTerra white paper is available on the newly updated ExTerra website! Check it out at http://www.geoprisms.nineplanetsllc.com/scd/exterra.html . The white paper is the product of the labor of many people over many years, with an especially intensive effort this fall. Thanks to all who contributed! Thanks also to Anaïs Ferot and the GeoPRISMS office for revamping our website. Thanks, finally, to NSF Petrology and Geochemistry for their support of the ExTerra workshop at Goldschmidt this past August, which helped define the science questions in the white paper and gave us the push needed to refine our ideas about future field institutes. We are running a small pilot field institute in the Santa Lucia Mountains in California this coming summer and are planning a field institute in the Alps in summer 2015, so stay tuned!

Best wishes,

Sarah Penniston-Dorland and Maureen Feineman

Session 5: Mantle to Crust
•    05b: Magma Generation/Evolution and Oceanic Crust Formation at Mid-Ocean Ridges and Interoceanic Arcs

Magmatism in the ocean basins is responsible for forming the igneous crust of two-thirds of Earth’s surface and for a significant portion of mass and heat transfer from the mantle into the oceanic crust and oceans. Petrologic, geochemical, geochronological and geophysical studies of oceanic magmas at a range of spatial and temporal scales (from single eruptions to volcano-scale sampling) in both extrusive and intrusive sections (e.g., by drilling and in ophiolites) have revealed the operation of a wide range of magmatic processes. This session will investigate the latest results to inform our understanding of how the full range of these processes and conditions act to control oceanic magmatism at spreading centers and arcs (including mantle melting style and depth, mantle fluids and metasomatism, melt-rock reactions in the mantle and crust, and eruption of magmas or entrapment as plutons). The session welcomes contributions from petrological, geochemical, geochronological, geophysical, experimental and modeling studies of igneous processes and oceanic crust formation in modern and ancient oceanic settings.

Keynote speaker: Sensumu Umino
Invited Speakers: Dorsey Wanless (and others pending their acceptance).
Convenors: Ken Rubin, Laurence Coogan, Yaoling Niu

•    05f: Serpentinization Processes: From Mantle to Microbe, Past and Present (Conveners: Muriel Andreani, Susan Lang, Thomas McCollom)

Session 6: Continental Crust
•    06c: Putting the Little “t” in P-T-H2O-T: Novel Integrations of Geochronology and Thermodynamics in Diverse Tectonic Regimes (Conveners: Ethan Baxter, Michael Williams, Stacia Gordon, Clare Warren, Emilie Janots)
•    06e: The Dynamic Margins of Continents (Conveners: Oliver Jagoutz, Mark Behn, Mihai Ducea, Peter Clift)

Session 7: Subduction
•    07a: Geochemical, Petrological, and Physical Controls on Arc Eruptions (Conveners: Caroline Bouvet de Maissoneuve, Philipp Ruprecht, Tom Shea)

•    07b: New Advances in Subduction Zone Magma Genesis
Magmatism at the Earth’s dynamic subduction zones generates volatile-rich, andesitic magmas that resemble continental crust in composition and form an integral part of the broader geochemical cycles on Earth. The plate tectonic concept brought the recognition that andesite genesis is causally linked to slab subduction and major strides have been made in the past decades towards understanding subduction cycling. However, it remains unclear the extent recycled slab materials (subducted trench sediment, igneous oceanic crust, serpentinitized mantle, and eroded crust) affect the major and trace element chemistry of primary arc melts. How much slab material is contained in primary arc magmas? Are primary arc magmas basaltic or silicic or both? How are slab materials principally transferred to the mantle (fluids? silicic melts? mélange diapirs?). Do these components react and hybridize with the subarc mantle, or rather pass through it? What is the role of the overlying crust in modifying melt compositions? What are the timescales of slab material transfer through mantle and crust? This session seeks new concepts of material processing at convergent margin that challenge the classical model of basaltic arc magma formation from subarc mantle with only minor mass contributions from the subducted slab. Case studies and conceptual approaches from all disciplines are welcome, including field studies, experimental petrology and geophysical approaches ranging from fluid dynamics to seismology. Contributions that address the quantification of mass transfer from slab to arc are particularly encouraged.

Keynote speaker: Arturo Gomez-Tuena (on slab diapirism and more)

Apply to Test MARGINS Mini-Lessons in Your Classroom
The GeoPRISMS-hosted MARGINS Mini-Lesson Project (a.k.a., “Bringing NSF MARGINS Continental Margins Research Into the Undergraduate Curriculum”) has developed a suite of mini-lessons designed to integrate the successful decade of NSF MARGINS research into the undergraduate geoscience curricula.  As with the MARGINS Program, the mini-lessons are organized around four initiatives, focused on the following science topics: chemical cycling in subduction zones (SubFac), seismogenic zone processes at subduction zones (SEIZE), rupturing continental lithosphere (RCL), and source to sink sediment cycling at continental margins (S2S). MARGINS research provided critical new observations and insights into the fundamental geologic processes along continental margins, enabling data rich learning opportunities for upper-level undergraduate students.
We invite you to apply to test one or more of the MARGINS mini-lessons in your classroom – this semester or next.  For more information about the project and in-class field testing, to browse the collection of mini-lessons, and to express your interest in joining the effort, please visit the following site:
http://serc.carleton.edu/margins/test_curr.html
Further questions and inquiries should be directed to Juli Morgan, MARGINS Mini-Lesson Project Lead <morganj@rice.edu>.
We look forward to hearing from you!
