In particular\, moderately volatile elements (MVEs) have distinct differences in depletion between the meteorite groups and the planets. Understanding the chemical effects of impacts and post-impact processes are necessary in order to place constraints on the bulk composition of the planet (pre-differentiation). Vaporizing collisions\, common in energetic periods of accretion such giant planet migration and the terrestrial giant impact stage\, can separate refractory and volatile components as the system re-equilibrates during vapor plume expansion and cooling. In order to understand the chemical changes caused by high velocity collisions\, we must know the liquid-vapor phase boundary of the dominant mineral(s) of the original bodies\, likely a silicate mineral such as olivine or pyroxene. To constrain the equations of state of these minerals\, we conducted shock-and-release experiments with the Sandia Z machine on single crystal forsterite\, olivine\, and bronzite to determine the pressure (P)\, temperature (T)\, entropy\, and density of the shocked and post-shocked states. \nUpon decompression from the shocked state\, the high pressure fluid intersects the phase boundary and separates into a two-phase mixture at high P and T (e.g.\, ~1–1000 bar and ~4000–6500 K)\, driving melt-vapor partitioning under near-equilibrium conditions with limited isotopic fractionation. As the system continues to cool\, the MVE concentrations evolve until the system reaches the triple point and the melt freezes. The remaining condensable vapor adsorbs onto the larger solid droplets or condenses as new dust. Thus\, the MVE concentrations in the post-impact system may have large variations that are correlated with particle size. We explore the hypothesis that impact vaporization leads to a net enrichment of MVEs in dust-sized particles. Nebular size-sorting processes may separate the larger\, MVE-poor solids and the MVE-rich dust\, creating zones of variable depletion. During accretion\, the MVE-enriched dust may be variably incorporated into planetesimals and contribute to the chemical diversity observed in meteorites and planets. \nSNL is managed by NTESS under DOE-NSSA contract DE-NA0003525.

As the core-mantle partitioning character of C and N strongly depends on fO2\, they can act as a powerful tracers to understand the fO2-dependent volatile accretion history of terrestrial bodies. Previous high P-T experimental studies have shown that the highly siderophile character of C increases with decrease in fO2\, but can get suppressed in systems with high fH2\, while N acts as a siderophile element at >IW–2.5 and is lithophile at 4 GPa) remain stable in equilibrium with an H2O-rich fluid. Above the solidus (between 800-850 °C from 3-7 GPa)\, carbonates remain stable along with silicate minerals (cpx\, olivine\, garnet) and a CO2-rich melt phase over a restricted temperature interval until carbonates are completely melted out at T > 1000 °C at 3-5 GPa and > 1100 °C at 7 GPa. \nDue to the breakdown of chlorite at conditions above 3 GPa and 800 °C our experiments suggest that ophicarbonates will be nearly completely dehydrated at subarc depths\, delivering H2O to arc magma source regions. The stability of carbonates in our experiments suggest that even for the hottest subduction zones\, ophicarbonates in the mantle lithosphere (below slab MOHO) can retain C in the form of crystalline carbonates past subarc depths and deliver C deeper into the mantle. If ophicarbonates formed in the mantle wedge become mechanically coupled with the subducting slab\, then C can be completely released in the hottest subduction zones in the form of CO2-rich melts\, while ophicarbonates in cooler subduction zones may retain some C. In agreement with previous modeling studies3\, the present experimental study suggests that ophicarbonates dehydrate and deliver H2O to arc magma source regions and retain some amount of C in all but the hottest subduction zones\, highlighting the importance of these lithologies in delivering C past subarc depths deep into the mantle. \n1Alt\, J.

As a result\, planet formation produces unfamiliar phenomena\, such impact-generated vapor bubbles in the solar nebula and fast-spinning synestias. These newly recognized phenomena lead to fresh views on how to use geochemical observations to reconstruct planet formation.
