The deep carbon cycle in Earth and other planetary bodies including

meteorite parent bodies depends on the structure and stability of

carbon-bearing minerals, melts and fluids at high pressure and temperature.

Recent advances are providing new insights into novel structures and

properties of native carbon phases, carbonate minerals, ices, clathrates,

carbides, and phases containing trace carbon. Carbon solubility in liquids

is important for understanding metal and silicate portions of planetary

interiors, and fluids containing carbon play important roles in elemental

mass transfer. This session highlights the roles of carbon in crystals,

melts and fluids in the deep carbon cycle in the terrestrial planets. We

welcome contributions based on any combination of computational,

experimental, and theoretical mineral physics and petrology, including work

on individual carbon-bearing phases and on their stability and reactivity

with multiphase assemblages.
