Do you think that microstructures hold the key to unravel natural processes?
Do you feel the need to understand why an intriguing microstructures is 
exactly the way it is?
Or simply the microscope is your favorite tool to work on natural and/or 
synthetic materials?
After a very successful session last year, with great talks and a very 
eager audience, we would like to invite you to submit your contribution 
to another wonderful session which focusses on the power of 
microstructures to unravel metamorphic/magmatic processes at the EGU 
2019, in Vienna!

GMPV1.2 “Peering into the past: the power of microstructures to unravel 
metamorphic and igneous processes”
https://meetingorganizer.copernicus.org/EGU2019/session/32710

Conveners: Silvio Ferrero (Universität Potsdam), Gautier Nicoli 
(University of Cambridge), Brendan Dyck (Simon Fraser University) and 
Marian Holness (University of Cambridge)

The microstructure of igneous and metamorphic rocks are archives 
preserving abundant information about rock history, such as heating and 
cooling rates, metasomatism and fluid infiltration, timing and location 
of nucleation and crystal growth, crystallisation regime, and the 
extent, mechanisms and timing of deformation. Microstructural features 
achieve even greater importance when combined with geochemical data, but 
their potential is commonly under-recognised.

We welcome contributions covering the entire range of igneous and 
metamorphic petrology, which either showcase development of new 
microstructural analysis techniques or new applications of 
well-established techniques, or illustrate how microstructural 
interpretation adds to our understanding of rock history. We anticipate 
that this broadly-conceived session will trigger exciting new synergies 
across a wide range of microstructural studies.

Confirmed invited presentations: for the lovers of high grade 
metamorphic rocks, Bruna B. Carvalho (University of Padova, Italy) will 
present the talk "Melt and fluid inclusions in migmatites: unravelling 
anatexis and fluid regime of the deep crust". For the fans of magmatic 
rocks, we are working on having a great invited speaker - stay tuned!

We are very much looking forward to seeing you in Vienna.
