| An Analysis of Geo - anomaly Spatial Structure Based on GIS |

| Abstract:GIS has four main advantages in geosciences: data acquisition, data management, spatial analysis and output function. As a new mineral exploration theory, geo-anomaly has very important instructive significance in looking for and locating ore-forming targets. In view of the sensitive and effective character of GIS in analyzing geo-anomaly, this paper tries to combine geo-anomaly with GIS. The authors on thfe one hand described in detail the concept of geo-anomaly as well as the study method and on the other hand took the Jiaodong gold concentration area as an example to discuss the method for analyzing geo-anomaly spatial structure based on GIS. The research results indicate that the method is scientific and effective in analyzing geo-anomaly spatial structure based on GIS, which is the key to the utilization of GIS in ore prognosis. |
