摘要
Using both ERDAS IMAGINE 9.1 and MAPGIS 6.7,the authors extracted abnormal surplus gravity slope and magnet slope and,with the help of the known relationships between mineral deposits and the abnormal surplus gravity slopes and magnet slopes,reached the following conclusions: Where the gravity slope is within 62°-73°(the value of the surplus gravity is enlarged by 15 times) and the value of the surplus gravity is within-3-1 m / s2,the conditions are favorable for mineralization;in the north,where the magnet slopes are within 40°-50° and 61°-70°,the conditions are favorable for mineralization;in the west,where the magnet slopes are less than 30° and the value of the abnormal magnet is within-40--45 nT,the conditions are favorable for mineralization;in the whole mineral deposit,where the magnet slopes are within 71°-80° and the abnormal value of magnet is less than zero,the conditions are favorable for mineralization.The extracted abnormal surplus gravity slope and the abnormal magnet slope can reflect the favorable ore-forming places in the depth,and thus can play a guiding role in deep ore-prospecting work.
