DOI: 10.1007/s00410-018-1456-3
Abstract: This study reports a geochemical investigation of two thick basalt sequences, exposed in the Bracco–Levanto ophiolite (northern Apennine, Italy) and in the Balagne ophiolite (central-northern Corsica, France). These ophiolites are considered to represent an oceanward… read more here.

DOI: 10.1016/j.gsf.2018.11.001
Abstract: Abstract The compositional variability of the lithospheric mantle at extensional settings is largely caused by the reactive percolation of uprising melts in the thermal boundary layer and in lithospheric environments. The Alpine-Apennine (A-A) ophiolites are… read more here.

DOI: 10.1016/j.lithos.2018.02.025
Abstract: Abstract Recent studies investigate the replacive formation of hybrid troctolites from mantle peridotites after multiple stages of melt-rock reaction. However, these studies are not conducted in a field-controlled geological setting displaying the clear evolution from… read more here.

DOI: 10.1016/j.lithos.2021.106427
Abstract: Abstract Melt-rock interactions are important for understanding the long-term evolution of the Earth and for addressing various mantle compositions. However, details of the mechanisms and evolution of interactions in supra-subduction zones remain poorly understood. This… read more here.

Multi-stage Reactive Formation of Troctolites in Slow-spreading Oceanic Lithosphere (Erro–Tobbio, Italy): a Combined Field and Petrochemical Study
Sign Up to like & getrecommendations! Published in 2019 at "Journal of Petrology"
DOI: 10.1093/petrology/egz019
Abstract: Many recent studies have investigated the replacive formation of troctolites from mantle protoliths and the compositional evolution of the percolating melt during melt–rock interaction processes. However, strong structural and geochemical constraints for a replacive origin… read more here.
