Abstract

This work is conducted to study the mineralogical, petrographic and geochemical aspects of the basic volcanic Neogene rocks (hawaiites) as persistent in the Nefza region (northern Tunisia), and their alteration outcomes. The outcrops, as studied in the area, are those belonging to Moktaa El Hadid. These rocks appear to display argilization associated with weathering and significant hydrothermal circulation [1]. Among the magnetic minerals, titanomagnetites are the most abundant and represent the major spinel in basalts.
