| Abstract: | A high-precision forecasting model using the “f ield theory-field structure analysis-field simulation” has been establish ed to predict the concealed orebody. In order to form the best predicting pattern, the couplin g analysis of anomalous structure, metallogenic structure, selected and optimize d forecasting information system are used in the construction of the model. Tech nologies involved in the modeling also include analysis of the fine structures o f geological and geophysical explorations, geochemical explorations of anomalous fields and metallogenic field of the forecasting target, as well as the constru ction of space location of the orebody in the target area. The forecasting model presented in this paper has been employed in a typical hydrothermal-vein-like gold deposit located in the northwestern Jiaodong peninsular to forecast the lo cation of the concealed orebody. With the forecasting of deep concealed orebody as an example, some problems worth further study are also outlined and discussed . |
