摘要

•Neoproterozoic metavolcanics from Wedel Jarlsberg Land and Nördenskiold Land, Svalbard trace magma-crust interaction.•The crustal assimilants change geographically reflecting the depositional environment of the sedimentary crust.•The metatuffs have mechanically assimilated shales during eruption.
