Abstract

In the southern end of the Iglesiente-Sulcis district where several Mo-prospects occur in close association with leucogranite bodies, molybdenite has been sporadically exploited in the past throughout the mineralized areas. The low grade mineralizations occur mainly as MoS2 bearing quartz veins, in high silica intrusives throughout a granitic batholith of Hercynian age. Ores and alterations are usually centered on stocks of leucogranite-porphyry or fine grained varieties of leucogranites so that these metal showings can be considered porphyry-style mineralizations. Petrographic and geochemical investigations provided interesting relationships between the magma and the nature of mineralizations.
