Abstract
At present, a global crisis of mineral resources is accelerated at a growing rate and many countries are facing the challenge of time. Therefore, the policy-makers of various countries have formulated appropriate countermeasures to convert tactic goal into strategic objective or combine both to a general pattern as a game of chess. The tendency from traditional type to opening type reflects the difficulty of metallogenic prediction increasing and it is urgently necessary to deepen the exploration for concealed deposit. Traditional classic theory, modern theory and fuzzy theory are commonly adopted to guide research. These theories have respective superiorities, but their common defect is that they can't make long-term control. In order to conquer the insufficiency mentioned above, the authors have discussed on concealed deposit by using the grey theory and discovered that this research area belongs to grey metallogenic system of intension type. Thinking is widened by the dissection of several typical examples. The concept, definition and classification of so-called “concealed deposit” are considered to be further discussed. Hence the new concept “concealed form type deposit” is suggested. Aimed at the grey characters of metallogenic system, the strategic countermeasure researching program of grey prediction and decision making have been formulated. The promise of this new area is extensive, and the theoretical significance of the research in this area and practical guiding action are profound.
