Fabrics produced mimetically during static metamorphism in retrogressed eclogites from the Zermatt-Saas zone, Western Italian Alps

► Lattice preferred orientations can occur through mimicry of pre-existing LPO. ► The interphase misorientation distribution analysis tool can identify LPO mimicry. ► Barroisite can replace omphacite via a 180° rotation around the omphacite <001> axis. ► Barrosite can replace glaucophane by copying its crystal lattice exactly. ► Retrogression and exhumation of Punta Telcio eclogites was for a time static.
