Sardinia Province

The Sardinia Province contains a wide variety of rocks, ranging from subalkaline to Na alkaline and nephelinitic, and from mafic to felsic. Most rocks have relatively unradiogenic Sr and Pb isotopic signatures, resembling EMI mantle compositions. A few outcrops from southern Sardinia have isotopic and trace element signatures very close to the rocks of the Sicily Province. Plio-Quatemary volcanism in Sardinia overlies Oligo-cene-Miocene arc-type tholeiitic to calc-alkaline volcanism. 

Fig. 1.1. Distribution, petrochemical affinity and ages of the main Plio-Quatemary magmatic centres in Italy. Location of the Eocene igneous body of Pietre Nere (Apulia) and of the Oligocene to Miocene magmatic provinces of Sardinia, Western Alps and Veneto is also indicated. Open symbols refer to outcrops below the sea level.

Radiogenic isotopic variations for Sardinia Plio-Quaternary volcanics are accompanied by systematic modifications of trace element ratios (Lustrino et al. 2004a). For instance, Ba/Nb is higher in the northern than in the southern outcrops, whereas Ce/Pb is lower (Fig. 9.9). In general terms, the rocks from the southern occurrences have incompatible element ratios close to typical anorogenic magmas such as those of the Sicily Province,... 

Italy,Sardinia,England,in the United Provinces of India and in Argentina.However, Wespi had shown a correlation between the decline of deaf-mutism and the extent of salt iodination which was introduced independently in several Swiss cantons.This correlation was only time related and other factors could equally have been responsible. Wespi s analysis was subsequently disputed on the ground that no cretins were born about the time the iodine prophylaxis was introduced, indeed, all the cretins were born at least 10 years previously.
