Dear colleagues, Apologies for multiple postings. We would like to call your attention to the session: Theme 4c - Reading between the minerals - the chemical consequence of crustal anatexis on rocks and magmas which will take place in the Goldschmidt 2023 – Lyon (France) from July 9th to 14th. The conference will have a hybrid format allowing in person presentations in Lyon, as well as online presentations. Abstract submission is now open (deadline is March 1st) and we invite you to submit to our work session. Keynote speaker will be Melanie Finch (James Cook University). Please see the session description below. More information can be found on the Goldschmidt 2023 website: https://conf.goldschmidt.info/goldschmidt/2023/meetingapp.cgi/Session/4318<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fconf.goldschmidt.info%2Fgoldschmidt%2F2023%2Fmeetingapp.cgi%2FSession%2F4318&data=05%7C01%7Csilvio.ferrero%40unicadrsi.onmicrosoft.com%7Ce4c2e061974f464985f508dafdf02d30%7C6bfa74ccfe344d5797d397fd6e0edee1%7C0%7C0%7C638101505447660168%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=v25xjHmKDux0MT%2Fi%2B%2FQ9AaSl1rNdj5o4TNJcJiycVPk%3D&reserved=0> Session Description: Partial melting during (U)HT metamorphism and transfer of anatectic melts are key mechanisms that shape the chemical differentiation of continental crust and have a major impact on the tectonic evolution of orogens. Furthermore, partial melting has results in chemical and isotopic fractionation between minerals, fluids and melts thereby shaping the chemistry of metamorphic and igneous rocks. However, the connection between the metamorphic source rock and the final solidified magmatic rock is often obscured by a multitude of potential processes during ascent and a lack of continued exposure from the source to the emplacement region. Many methods and tools have emerged to address these important but often-obscured processes. From classic approaches of detailed field and microstructures documentation of melt migration to advances in thermodynamic modelling of phase assemblages and chemistry, to micro-analysis of melt and fluid inclusions, and finally, to crustal-scale modelling of reactive Yow process and magma transport through the crust. We invite contributions from metamorphic, igneous, and experimental petrology as well as numerical modelling dedicated to understanding metamorphism, partial melting, and magma generation and ascent in the continental crust. On behalf of all the conveners, Silvio Ferrero _________________ Prof. Silvio Ferrero Professor (Associate) of Petrology / Professore Associato di Petrologia Università degli Studi di Cagliari Dipartimento di Scienze Chimiche e Geologiche Blocco A, Cittadella Universitaria, 09042 Monserrato (CA) "In those early days people laughed at me. They quoted Saussure who had said that it was not a proper thing to examine mountains with microscopes, and ridiculed my action in every way. Most luckily I took no notice of them" (Henry Clifton Sorby) ​ To many petrologists a volatile component is exactly like a Maxwell daemon; it does just what one may wish it to do.
