The distribution of the different forms of sulfur in coal seams of Sulcis tertiary coalfield , SW Sardinia, has been investigated . A total of 165 samples has been collected, both core samples and channel samples along drifts . The total sulfur content, detected by traditional methods, shows a mean value of 6.6 %. The organic sulfur, detected by microprobe analysis , shows a mean value of 3.7 %, and forms the 60 % of total sulfur. Finally, the mineral sulfur, worked out by difference between previous values, shows a mean value of 2.6%. The data treatment led to draw up the iso-value curves of sulfur maps as forecasting tools in mining development.
