英文摘要： Modern nonlinear theory applied to the mineral resources exploration and evaluation is one of the hottest topics of geoscience research. It has been demonstrated that the nonlinear models relevant to multifractal singularity theory are not only effective useful for characterizing the mineralization system, the ore-forming process, mineralization enrichment patterns,but also for recognizing and retrieve geoanomalies associated with mineralization, which has resulted in an effective new approach for mapping mineral resources and quantitative assessment. The project summarizes main achievements of Gejiu tin polymetallic deposit research, around the strategic information prospecting for the "concealed" and "difficult to identify "mineral resources,proposed a effective mehod based on singularity theory to solve two key problems in quantative predition :"modeling and quantifying ore-controlling factors and prospecting indicators"and" recognizing geoanomalies caused by buried source "，to quantitative revealling geological ore-controling factors regularity, the geochemical elements local enrichment and accumulation .The integrated anomalies associated with mineralization quantitative prediction model is applied to mineral resources quantitative prediton and evaluation of Gejiu .This work can also support the ongoin
