Subject: Goldschmidt session 04i: "Magma Genesis Beneath Oceans and Continents: Source Signatures and Melting Processes"
***************************************************************************************************************
Dear colleagues,
With the deadline for Goldschmidt abstracts coming up at the end of next month (March 30th, 2018), we would like to invite you to submit your abstract to a session which may appeal to readers of the Volcanolist.
Session 04i:
Magma Genesis Beneath Oceans and Continents: Source Signatures and Melting Processes
Lavas erupted at mid-ocean ridges, ocean islands, and in intra-continental settings show both spatial and temporal variability in their chemical and isotopic compositions. This variability contains a wealth of information about mantle sources and magma genesis and is interpreted to be either an _expression_ of long-lived chemical heterogeneity of the mantle source or physical heterogeneity of the melt generation and magma transport processes. The former considers spatial variations of elements in the mantle prior to melting; while the latter is typically discussed in terms of source fusability, magmatic segregation and melt-rock reaction, which control the length scales, time scales and fluxes of melt ascent. Ultimately, it is likely that both source and process are controlling the lava's composition. This session invites contributions of observations, experiments and models, and their combined application, to help disentangle how mantle heterogeneity and melting processes are manifest in the chemical and isotopic compositions of basalts from mid-ocean ridges, ocean islands and continental interiors.
Confirmed keynote: Jessica Warren (University of Delaware)
The conference will be held from August 12th-17th in Boston, USA. Further details can be found on the conference website: https://goldschmidt.info/2018/index
Best wishes, session 04i conveners: Oliver Shorttle (University of Cambridge), Lucy McGee (Macquarie University), Ken Sims (University of Wyoming) and Richard Katz (Oxford University)
