THE MINERALOGICAL, GEOCHEMICAL, MAGNETIC PROPERTIES OF ALKALINE BASALTS AND ASSOCIATED ROCKS FROM THE SOUTHERN AREA OF THE PERSANI MOUNTAINS. USE OF THIS DATA IN THE THREE-DIMENSIONAL MODELING OF THE GEOLOGY OF THIS REGION.
Abstract
Alkaline basalts in the southern area of the Persani Mountains are of particular interest for studying the tectonic evolution of the area at the end of Neogen and the beginning of the Quaternary. It is also very important the existence of an important amount of ultra-basic xenolites in these rocks. These xenoliths provide important information about lithology, chemistry, and the evolution of the lithospheric mantle in the area. For this purpose, we analyzed 30 samples of both basalts and xenolite samples. The samples were analyzed by optical microscopy, in thin sections, and electron microscopy and as well as by Rx difractometry to determine the chemical composition in oxides of each analyzed sample. Density and magnetic susceptibility determinations have also been made. As a result of the investigations, there was a hydration phenomenon of the mantle formations, before the uplifting of xenolite from the mantle to the surface. This suggests an older interaction of mantle with crust formations. The results of these investigations, along with the coordinates of the sites that were tested, will be entered into the database to be used to create the three-dimensional geological model of the area. Within this model, besides the physical properties of these rocks, it is important to know their thickness as well as the knowledge of the lithology and physical characteristics of the formations over which they have been deposited.
