In the Arburese region (SW Sardinia, Italy) several vein-type ore deposits, including small Sn minerali-zations, are arranged, with different trends, around two contrasting late-to post-collisional shallow plutons: the Arbus and the Monte Linas plutons, dated at 304 ± 1Ma, and 289 ± 1Ma respectively. These intrusions belong to two different ilmenite suites: an earlier high-K rock-series (Arbus Pluton), and a later Fbearing rock-series (Monte Linas Pluton). In the apical portion, close to the host rocks, they suffered greisen type alteration testified by secondary muscovite, B-rich and F-bearing phases. Preliminary fluid inclusion analyses in cassiterite veins, documented polyphase mineralizations and temperature close to 400°C. The petrochemical features and the emplacement history of the Linas pluton meet high favourability for tin accumulation. Despite of their limited extent, the Sn ores of SW Sardinia have a metallogenic relevance as they document a long lasting metallogenic epoch all over the South Variscan Realm.
