Redox is one of the keys for understanding Earth oxygenation, magmatism and volcanism, from magma-genesis, through crystallization to volcanic degassing. Furthermore, redox plays a fundamental role for material processes: its understanding allows bridging important gaps between material and Earth sciences. The objective of the session is to promote the links between atomic-scale structures, macroscopic properties, and igneous processes occurring on Earth.

 We strongly encourage the submission of contributions about the role of redox on:

-i) melt/glass thermodynamics with emphasis on mixing properties (including first principles approaches)

-ii) spectroscopic evidence for short-medium range structure

-iii) role of cationic and anionic interactions on transport properties

-iv) volatile solubility and diffusivity

-v) speciation behavior, with emphasis on volatiles and trace elements

-vi) glass transition and rheology of magmas

-vii) experimental and computational determination of phase diagrams, particularly in volatile-bearing systems

-viii) reconstruction of igneous processes from bactracking of redox data in natural samples
