URL: From rhodri.davies at anu.edu.au Thu Feb 8 21:23:03 2018 From: rhodri.davies at anu.edu.au (Rhodri Davies) Date: Thu, 8 Feb 2018 10:23:03 +0000 Subject: [Geodynamics] Goldschmidt: 2018 Message-ID: <38111A6A-268A-4CC6-81DD-2E5F71C9155E@anu.edu.au> We are inviting submissions to the following Goldschmidt 2018 session: 02f: Mineralogy, Petrology and Processes in the Mantle Transition Zone and the Lower Mantle which is convened by Greg Yaxley, Antony Burnham, Rhodri Davies and Mike Walter. Our Key Note speaker will be Prof Robert van der Hilst (MIT). We also have an invited speaker - Dr Tim Jones (ANU and Carnegie). We are really hoping to attract talks and posters in which interpretation of geochemical and petrological observations on natural samples or high pressure experiments relevant to the mantle transition zone and lower mantle, can be informed by geophysics, mineral physics and geodynamics. We look forward to receiving your abstracts by the deadline of March 30. The session description is reproduced below. The Earth?s mantle transition zone (MTZ) is that region of the mantle bounded by global seismic discontinuities at depths of 410 and 660 km. These depths closely correspond to phase transitions of upper mantle olivine to the wadsleyite structure and ringwoodite to bridgmanite and ferropericlase, respectively. The latter mineral assemblage is stable almost all the way to the outer core, with post-perovskite replacing bridgmanite only at the base of the lower mantle. Recent suggestions that these extremely deep parts of the earth may be very significant reservoirs of water, and inferences that some diamonds formed there, have profound implications for a range of petrological and physical processes, as well as for understanding the Earth?s deep water and carbon cycles. This session invites multidisciplinary contributions from geochemistry, petrology, geophysics, geodynamics and mineral physics that explore the nature of the MTZ and the lower mantle, and processes occurring within them. Questions to be addressed might include (1) How do sub-lithospheric diamonds and their inclusions form? (2) How do they get to the surface? (3) What do they tell us about the abundances, speciation and physical distribution of volatiles in the MTZ and lower mantle? (4) What lithologies are present, what are their chemical compositions and physical distributions, and how does this relate to the isotopic variability seen in oceanic basalts? (5) What are the physical properties of the MTZ and lower mantle and what constraints do they place on chemistry and mineralogy? (6) What effects do volatiles have on physical properties of these lithologies under the relevant conditions? (7) What is the temperature distribution in the MTZ and lower mantle? (8) Could melts exist there? (9) What roles do deeply subducted slabs play in MTZ and lower mantle processes?

The positions are fully funded for three years. The salary is competitive and in accordance with Swiss National Science Foundation standards. The goal of this project is to obtain a systematic understanding of how the current state of Mars has arisen as a result of 4.5 billion years of evolution from an early post-accretion phase that included a giant impact forming the crustal dichotomy. The project is based on numerical modelling constrained by observations, including expected new observations by the Mars InSight Lander. One PhD project will be carried out in the Geophysical Fluid Dynamics group led by Prof. Paul Tackley, a diverse group of ~20 scientists working on a range of problems related to crust, lithosphere and mantle dynamics on the Earth, planets and moons. The working language is English. This goal of this subproject to study the evolution from the post-impact structure to the present day by running a large number of 3-D simulations of Mars? thermo-chemical evolution and using machine learning to compare results with observations. The other PhD project will be carried out in the Theoretical Astrophysics and Planetary Science group (a member of the Center for Space and Habitability) at the University of Bern, and will be supervised by PD Dr. Martin Jutzi. This subproject focusses on impact simulations using a smoothed-particle hydrodynamics approach coupled with global models of the immediate post-impact phase, which track in particular the cooling and solidification of the resulting regional magma ocean and the sinking and merging of the impactor core with Mars? core. Both students will also collaborate with a team at the Bayerisches Geoinstitut, led by Prof. Gregor Golabek. Requirements: Applicants must have an MSc or diploma in Earth science, Astronomy, Physics, or other relevant field such as mathematics. Experience in programming and numerical modeling is beneficial, as is knowledge of fluid dynamics and applied mathematics. Start date: June 1st 2018 or soon thereafter. How to apply: Send by email to Professor Paul Tackley (ptackley at ethz.ch ) or PD Dr. Martin Jutzi (martin.jutzi at space.unibe.ch ): (1) A curriculum vitae and a list of publications (if applicable). (2) Details of your BSc and MSc, including copies of transcripts showing lists of courses with grades. (3) A brief statement about their research interests, motivation and skills. (4) Names, addresses and emails of two references that may be contacted for a recommendation letter. Deadline: Complete applications received by April 1st, 2018, will receive full consideration. After this date, applications will be considered depending on availability. -------------- next part -------------- An HTML attachment was scrubbed...

AGCC 2018 will focus on the Asia Pacific region and is supported by all eight Member Organisations of the Australian Geoscience Council. ?Big Issues and Ideas in Geoscience? is designed to highlight the fundamental role that Geoscience has as a major field of science throughout the Asia-Pacific region ? one that has a part to play in the life of everyone. The convention will cover all aspects of Geoscience, with technical themes covering theoretical and applied Geoscience, mineral and energy resources, environmental and societal science, Geoscience education and communication, and emerging technologies.
