Abstract: Abstract：The element temporal-spatial distribution characteristics of systems are studied in the exploration-geochemical context by using element abundances, variation coefficients, and degrees of element disorder. On the basis of that study, the recognition and prediction of large ore deposit clusters are discussed and a prediction model is constructed. The authors suggest that attention should be paid to surficial geochemical processes when the element abundances, variation coefficients, and degrees of element disorder are used to evaluate a large ore deposit cluster and point out that this model is suitable to the important condition that there exists an internal relation between an element cluster and the geologic body in which the element cluster is hosted”. It is concluded that the Carboniferous pyroclastic rocks should be the target for gold search in Xinjiang.
