From the petrogenetic study is established that pluton of Trujillo is an porphyritic adamellite, crystallised in three phases with an alteration one. Later, the porphyritic microadamellite crystallised in three petrogenetic facies: biotitic, leucocratic and turmaline. Each facies has three crystalitation phases and an alteration one. The major elements were analysed in adamellites, microadamellites and contacts between tugsten veins and porphyritic adamellite. From Harker, AFM and CaO-Na2O-K2O diagrams is emphasized an alcaline and peraluminic character. The distribution of trace elements is agree with the material evolution; Rb, Cs. Sr. Ba y Li settle better this connection.
