求同理论指导下的无模型预测

NONMODEL PREDICTION BASED ON FINDING IDENTITY THEORY

在地质背景相同（或相似）的环境中，已发现的矿床数较少而难以建立统计模型的情况下，本文讨论了基于求同理论指导下的无模型预测法。其思路为区求同—点求同，理论依据是同一类矿床成矿变异特征有其相似性，因而只要我们选择恰当的统计参数和方法，确定它与成矿因素的联系，就可以按亲合度对其分类，并作出合乎实际的解释，进而达到预测的目的。

In the same geological background, the number of discovered deposits is too few to construct a statistical model.In this paper,the author discusses the nonmodel prediction based upon finding identity theory.Its thought is region finding identity-point finding identity, and the basic theory is the similarity of the ore forming variation characteristics of same kind of deposits. Thus,provided that the chosen statistical paramenters and method are suitable, the relationship between the deposits and the ore forming factors can be determined, and then, the deposits can be classified according to the correlation, and a practical interpretation can be given and the goal of prediction target attained.
