Abstract
The "Horizontal Basalts" in the Agulo area are made up of a more than 600m thick succession of basaltie
flows that filled a SW-NE trending paleo-valley. Compositions vary between picrite and trachybasalt. The
lithologic and geochemical variability of these rocks indicates that they were generated mainly by fractional
crystalization. The recognition of several evolution cycles suggests the involvement of other processes
that modify the general fractional crystallization trend.
