BeschreibungPolino is made up of two small diatremes surrounded by layered tuffs and filled with breccia and carbonate-rich locks and lapilli (Pecerillo, 2005). It is classified as a carbonatite, the products of which consist of two facies: tuffisite and large carbonatite bombs. Both crustal and mantle lithics are also present within the welded tuff (Rosatelli et al., 2010). These deposits were Ar/Ar dated at about 246 ka (Peccerillo, 2005).
