非线性铀成矿作用--以上第三系砂岩型铀矿为例

本以滇西上第三系陆相砂岩铀矿为例研究非线性铀成矿作用。与铀矿化有关的参数可分为矿化参量和控制参量，矿化参量以及矿化在控制参量中的分布均遵从对数正态分布，控制参量(温度、压力和地球化学条件)的耦合作用对铀矿化的概率和平均品位的控制作用是非线性的，铀矿化在控制参量构成的相空间中的变化轨迹是一复杂的超曲面。非线性铀成矿作用具分形特征。

Nonlinear Uranium Mineralization:An Example from Neogene Sandstone-Type Uranium Ore Deposits

Geological action (process) is a nonequilibrium, nonlinear thermodynamic and dynamic system at open conditions.The Neogene continental uranium ore deposits in West Yunnan are studied as an example of nonlinear uranium mineralization in this paper.Different parameters related to the uranium mineralization are divided into mineralization and controlling parameters.All the mineralization parameter and their distribution in the controlling parameters follow logarithmic normal distribution.The coupling of controlling parameters (temperature,pressure and geochemical condition)are nonlinear to probability of uranium mineralization and average grade of ores.The change tract of the uranium mineralization in the 3 dimensional phase space formed by the controlling parameters is a complex hypersurface.Uranium nonlinear mineralization possesses fractal signature.
