Published in 2018 at "Lithos"

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.
