Metallogenic Rediction Of Xiaoxing'an Mountains–Zhangguangcai Mountains Area Base On Fractal Theory

The paper,according to Project "Hei Longjiang Xiaoxing'an Mountains – Zhangguangcai Mountains mining area metallogenic regularity and metallogenic prediction",comprehensive collection of regional comprehensive prospecting information.Based on the law of metallogenic prediction and theoretical methods,it makes use of fractal analysis to study the chemical characteristics of mineral elements in the study area.It use by the platform of Geographic Information System to process related basic data then drawing the map.By evaluation the comprehensive information we can get the distribution of mineral elements obtained in the study area.Combined mineral information and Mo,Zn,W three kinds of geochemical anomaly contour map elements delineate mineralization prospect area.According to the contour analysis on these 7 elements,such as Zn?Pb?Ag?Mo?Sn?Y?Nb.By element geochemical anomaly contour map study,to receive more metal element geochemical anomalies basic distribution;fractal analysis methods summation drawn exception threshold Mo,Zn,W three elements.Binding studies area known feature occurrences distribution forecast mineralization related elements favorable areas.Mo,Sn,W occurrences known deposits are mainly distributed in three elements unusually high value area,showing a good mineralization,mineralization is favorable locations.Obtained by the summation element geochemical anomaly value range and high degree of matching known deposits,favorable position to delineate mineralization has an important indication.Metallogenic element geochemical anomaly area of distribution is more concentrated.The geochemistry and geochemical anomalies,such as Pb,Zn,Mo,Ag,is a favorable sign of ore.Using the method of superposition in MAPGIS and combined with geochemical anomalies highlighted to outline the province of mining area.By contrast with nearly known mine deposits(points)and according to artificial experience,we can correct the mine prediction area.The results can provide the basis for mineral prospecting research.
