******************************************************************************************************
Hi Folks,
On
behalf of my co-conveners, I wish to draw your attention to a session
devoted to mineral replacement, alteration, stability, and reactivity at
the 2016 Goldschmidt Meeting in Yokohama, Japan (http://goldschmidt.info/2016/).
Session 18b: Mineral Replacement, Alteration, Stability and Reactivity on Earth and Other Bodies of the Solar System
Convenors: Hongwu Xu (hxu@xxxxxxxx), Hiroshi Kojitani (hiroshi.kojitani@xxxxxxxxxxxxxxx), Huifang Xu (hiroshi.kojitani@xxxxxxxxxxxxxxx), Timothy J. Fagan (fagan@xxxxxxxxx), Daniel Harlov, Adrian Brearley (brearley@xxxxxxx), Agnes Elmaleh (agnes.elmaleh@xxxxxxxxxxxxx), Olivier Vidal (olivier.vidal@xxxxxxxxxxxxxxx), Martine Gerard (martine.gerard@xxxxxxxxxxxxx)
Keynote: Alexandra Navrotsky (University of California at Davis, USA)
Invited Speakers: Andrew Putnis. Curtin University, Perth, Australia
Junfeng Ji, Nanjing University, Nanjing, China
Sasha Krot, University of Hawaii, Honolulu, Hawaii
Abstract
Many
geological processes are strongly influenced by the thermodynamic
stability and chemical reactivity of minerals, and investigating these
minerals as well as replacement and alteration assemblages and their
textures can provide clues to the geological processes as well as their
impact on the composition of the exosphere and on ecosystems. Aqueous
fluids play a key role, as they transport reacting species and may be
involved in dissolution and re-precipitation. This session will cover
experimental and computational studies on mineral stability and
reactivity at relevant temperature, pressure, and/or aqueous conditions,
and studies of mineral alteration based on experiment, theoretical
modelling and natural samples. Areas of interest include but are not
limited to high pressure and/or temperature phase
transformations/relations of mantle minerals, stability and kinetics of
nanophases/nanopores in the environment, mineral-fluid reactions at
various scenarios (e.g., CO2 sequestration), mineral replacements
related to mineral deposits or environmental issues, and implications of
alteration reactions in the broader context of geologic evolution of
distinct settings on the Earth and other planetary bodies.
Please encourage your students, postdocs, etc. to contribute to the session.
The on-line abstract submission deadline is February 26, 2016.
Information on the abstract submission process is available at: http://goldschmidt.info/2016/abstracts
Should any questions arise as to the suitability of the topic for
an abstract to the session, please feel free to contact either me or any
of the other co-conveners.
Best regards,
Daniel Harlov
