Dear colleagues,
Apologies for cross-posting. We would like to bring our session: Micro-To-Nanoscale Investigations of Terrestrial and Extraterrestrial Materials (4b), at Goldschmidt 2019 (Barcelona, August 18-23, 2019) to your attention.

Abstract submission closes March 29th (https://goldschmidt.info/2019/abstracts/instructions).

Please find the session description below.

Session 4b: Micro-To-Nanoscale Investigations of Terrestrial and Extraterrestrial Materials

Conveners: Anne-Magali Seydoux-Guillaumehttps://goldschmidt.info/2019/userView?userId=1865, Kimberly Tait

Keynote speaker: Ana Cernok (Royal Ontario Museum, Canada)

Complex dates and geological histories, even planet-scale events are preserved in natural materials. With the availability of new analytical techniques that can study materials on smaller and smaller scales, new observations can be made on the structural and chemical complexities in these materials. In particular, observing variations in trace element chemistry and zonation, deformation due to tectonic or impact events and alteration in terrestrial and extraterrestrial materials, to name a few. The recent developments in submicron-to nano-resolution analytical techniques (e.g. Atom Probe Tomography, Transmission Electron Microscopy, Transmission Kikuchi Diffraction, Electron Backscatter Diffraction, NanoSIMS etc.) allow researchers to resolve complex variations on new scale lengths. This session aims to bring together researchers focusing on the development and integration of micro-to nanoscale analytical techniques to terrestrial and extraterrestrial materials. We welcome a broad range of contributions that serve to highlight the current state-of-the art in material analysis and innovative application at the micro-to nanoscale. This session also aims to raise questions on the dating of minerals: what is the best analytical "volume" for in situ dating, what benefits does in situ nanoscale characterization have, compared to micrometric or bulk methods?

Thank you for considering submitting an abstract to our session,

Apologies for cross-posting. We would like to bring our session: Petrological
Evolution of Solar System Bodies through Experimental Studies (01e),
at *Goldschmidt
2019 *(in Barcelona, August 18–23, 2019) to your attention.

Abstract submission closes March 29th (
https://goldschmidt.info/2019/abstracts/instructions).

Please find the session description below. We encourage submissions from
all areas of experimental petrology, including surface conditions, lower
pressure/temperature conditions, and higher pressure/temperature conditions.

Session 01e: Petrological Evolution of Solar System Bodies Through
Experimental Studies

Understanding the processes by which rocky planetary bodies in our Solar
System differentiated into a core, mantle, and crust, and how this
differentiation influenced subsequent geologic events is crucial to
understanding the evolution of our Solar System. The aim of this session is
to bring together expertise from the various avenues of experimental
petrology-centric research within the overarching field of planetary
sciences in order to spark big picture and inter-disciplinary discussions.
Therefore, we encourage submissions from all areas of experimental studies
including surface conditions, lower pressure/temperature conditions, and
higher pressure/temperature conditions. We welcome abstracts that use
experimental techniques in order to understand 1) primary differentiation
processes of rocky planetary bodies, 2) primary geochemical aspects of
planetary bodies such as primary crust, mantle, and core compositions, 3)
secondary processes that influence the petrological evolution of Solar
System bodies.

Keynote Speaker: Rajdeep Dasgupta (Rice University)
