The Research Method of Large And Super-Large Ore Deposits For Synthetical Information Metallogenic Prediction

Researching for the super-large ore deposits (SOD) is considered a complicated problem. The SOD not only has the similar and even the same aspects in spatial-temporal distribution, ore controlling factors, metallogenic mechanism and metallogenic models, as the other common large, medium and small ore deposits, but has the special aspects for itself. It is necessary to study the SOD synthetically with different subjects, aspects , methods , ways and so on. According to the phenomenons of Cranes stand in the chickens' folk for the large and super-large ore deposits, the concentrated area and its basic division rules are proposed in the paper. The scope of remanent abnormal metallogenic elements and abnormal catch-basin and deep structure must be thought about during dividing the concentrated area's boundary, after studying the ore deposits distribution rules. Basing developing exploration engineering, it is discussed in the paper that the large and super-large ore deposits can be forecast, by summarizing the found ways of large and super-large ore deposits, such as finding the other ore deposits in the depth and outside of the old and known ore deposit, finding the large and super-large ore deposits by applying geochemistry methods, in the concentrated areas of medium and small ore deposits, with the metallogenic theories and models instruction, analyzing synthetic information synthetically and so on. In the paper, the ore deposits concentrated area and abnormal concentrated area are regarded respectively as the modeling and forecasting sector, in order to forecast the large and super-large ore deposits, through abstracting and evaluating the geology, geophysics, geochemistry, remote sensor and the other synthetic ore control factors, using mathematical statistics methods reasonably.
