This paper expand the knowledge of the spa$al and temporal evolu$on of a skarn ore deposit linked to igneous rocks (Campiglia Mari8ma, Italy). Collected data led to the reconstruc$on of an unusual sequence, in which a mafic porphyri$c magma -‐gene$cally linked with the skarn-‐ intruded the previously formed skarn. At Campiglia, there is evidence that mafic magma chased metasoma$c fluids, thus showing up an unforeseen behaviour of magma$c-‐hydrothermal systems.
