Objetivo TO ENHANCE INTEREST IN THIS ALMOST UNKNOWN BRANCH OF ALPINE METALLOGENY AND PROMOTE THE GLOBAL ASSESSMENT OF ASSOCIATED ORE DEPOSITS. The report presents the results of the comparative analysis of 2 Austroalpine areas of the Italian Alps where new discovered tungsten molybdenum (copper, gold) showings lie in connection with shallow level intrusions and dykes of Oligocene age: the Lago Verde-Lago Nero zone in the high Ultimo Valley (Ultental, South Tyrol) and the Cervo Valley near Biella (Piedmont). In terms of mineralization type and size, the economic significance of the stockwork ores spatially related to magmatic intrusions is low (Cervo Valley tungsten copper molybdenum showings in the innermost monzogranitic core to very low (Ultimo Valley, predominantly scheelite).Comparing the data from the rare earth element (REE) normal normalized content of the intermediate intrusives, mafic enclaves, porphyrite (andesitic) dykes and granites, 3 pattern types were recognizable: pattern A (the granitic dykes), pattern B (the porphyritic dykes) and pattern C (the mafic enclaves). It can be concluded that the granitic dykes (pattern A) do not derive by magmatic differentiation from the lithologies of patterns B and C. In turn, B and C lithologies are suggestive of 2 different sources, as it is also confirmed by the evolution trends shown by hygromagmaphile elements.Scheelite distribution results showed that, in the majority of cases, the mineral represents a normal (and often very scarce) accessory components of the main intermediate lithologies B and C. Positive correlation tungsten molybdenum in scheelite is evident. Paragenetically, scheelite is associated with accessory sphene and apatite, with aggregates of biotite flakes plus sulphides and with chlorite and quartz filling self sealing cavities in porphyrites.THE OBJECTIVE OF THE RESEARCH IS A NEW APPROACH TO THE GEODYNAMIC SIGNIFICANCE AND ECONOMIC POTENTIAL OF LATE ALPINE MAGMATISM IN TWO AREAS OF THE ITALIAN ALPS: VAL D'ULTIMO IN ALTO ADIGE, BIELLA-VALLE DEL CERVO IN PIEMONTE. FIELD AND LABORATORY WORK WILL BE DEVOTED TO A PRECISE DEFINITION OF FACIES AND ALTERATIONS. IT WILL INCLUDE THE STUDY OF FIELD RELATIONSHIPS AND FRACTURE PATTERNS ON ONE HAND, OF ISOTOPIC AND TRACE ELEMENT GEOCHEMISTRY ON THE OTHER. A MAGMATO-METALLOGENIC MODEL WILL BE SET UP.
