Mineral composition in cognate inclusions in Late Miocene-Early Pliocene potassic lamprophyres with affinities to lamproites from the Denizli region, Western Anatolia, Turkey: Implications for uppermost mantle processes in a back-arc setting

► Denizli “lamproite-like” lamprophyres include two distinct cognate inclusions. ► Geobarometric constraints suggest crystallization in the uppermost mantle. ► Fe-rich green-cores represent a mixture of distinct magmas. ► Melting of phlogopite pyroxenites in peridotites may explain their origin. ► Metasomatic agents of Denizli rocks are distinct from those of orogenic volcanic.
