Abstract:

The paper introduces a kind of new idea and method: “geophysicalgeological models of ore deposits” which is based on the geologic prospecting experience of thirty eight different kinds of metal deposits. Geophysicalgeological model of ore deposit is a visible prospecting model. As a combined concept of geological models and geophysical models of ore deposits, the model summarizes the orecontrol structures and the geophysical anomalies from which the spatial allocation pattern of ore bodies is abstracted. Thirty eight different kinds of metal deposits have been carried out the positioning prognosis of concealed ore deposits more effectively by integrated geological and EH4 HybridSource Magnetotelluric geophysical investigations. Based on the twelve types of geological models and eight types of geophysical models of ore deposits, eight types of geophysicalgeological models of ore deposits have been established in order to change positioning prognosis of hidden deposits from qualitative conceptual prognosis to quantitative positioning prognosis.

Key words: geophysicalgeological models, EH4 HybridSource Magnetotelluric, hidden ore bodies, positioning prognosis
