Forsterite from
Marsili Seamount (Marsili Volcano), Southern Tyrrhenian Sea, Tyrrhenian Sea, Italy

Locality type:Seamount
Comments:The olivine composition in the studied IAB-type lava samples is in the range Fo83.23-88.47 (Trua et al., 2010). Olivine is more forsteritic (Fo91–75) in the basalts than in the basaltic andesite (Fo78–74) (Trua et al. 2014).
Validity:Believed Valid
