By applying the theory and method of geological anomaly, it is focused on the analysis of the characters of major geological anomalies and their effect of mineralization in daye - jiurui region. the analysis result shows that the basement fault anomalies control a few major large hidden batholiths and their associated orefields ; that the anomalies of cover structure confine most cu - au deposits and fe - cu deposits within their scope ; that the geochemical anomalies and lithofacies - paleogeographical anomalies are major geological factors leading to trataboundness of some cu - au deposits ; that the anomalies of rock operties provide the favorable chemical and physical conditions for the ore - forming process, including the seepage, circulation, convergence and deposit of ore - bearing hydrothermal solution ; that the anomalous ctive stage of mesozoic magmatite is almost consistent with the major mineralization epoch of the fe, cu deposits, and the structure of multi - levels, and the zoning in magmatic system determine the spatial distribution of the mineralization system. then, based on the above analysis, a comprehensive variate, geological combination entropy, is brought forward for reflecting the complex degree of the combination of geological ore - controlling factors. after circumscribing the anomalies of geological combination entropy, the relations between the anomalies and ore deposits are determined
