In this paper, a cone-sheet intrussion, developed into the trachytic-phonolitic complex, is explained; as well as a new geological map is presented. Dikes, of trachytic and phonolitic composition often shows cooling margins, aphanitic texture and maffic inclussions. They cut through the basal complex, salic lava-flows and also fragmentary salic-deposits. Ir order to know the geological structure of the dikeswarn, strike and dip of many dikes was measured and lastly were plotted by stereographic projection. It is concluded that corresponds to a cone-sheet complex intrusion.
