摘要
本文试图从热水成因铀矿床的燕尾成矿模式出发(戴傑敏等,1983),建立起模式与实测厚度、品位的内在联系。通过燕尾闭域面积、跃迁幅度的数学分析,应用于地质成矿事件,认为:厚度分布溯源于燕尾闭域面积的收敛性,品位分布溯源于燕尾跃迁幅度的收敛性和叠加累积作。
In terms of the swallow-tail model for uranium deposits of hot water origin, this paper aims to establish the internal relationship between the model and some primary data on thickness and ore grade. Through the mathematical analysis of the swallow-tail model's closed domain area and transition saltus, which is applied to a geological metallogenetic event, the author holds that the distribution of ore thickness is related to the convergence of the swallow-tail closed domain area and the distribution of ore grade depends on the convergence, superimposition and accumulation of swallow-tail transition saltus.
