热水铀成矿作用的耗散结构

成矿元素地球化学表征了地壳中元素分布的空间结构，同一地质体中矿元素的初始含量服从正态分布，显示了一种无序的，均匀的空间对称结构，成矿作用就是在远离平衡条件下，成矿元素在有利的地政治协商会议化学条件下富集，初始的空间对称性发生破缺，演化有序的非均匀的空间结构，成矿作用的发生就是元素分布空间结构的转化。本文将铀矿化品位化为序参量，运用序参量演化方程和耗散结构理论，讨论了铀成矿体系的演化和生产铀矿化的条

URANIUM MINERALIZATION OF GEOTHERMAL GROUNDWATER AND DISSIPATIVE STRUCTURE

The spatial distribfution structures of ore-forming elements may be discribed by theirgeochemical fields in the earth. The initial content of a metallogenetic element follows the normaldistribution, representing a disordered homogeneous spatial symmetric structure. Given the conditions far away from equilibrium, the spatial symmetry would have been damaged and evolved toan ordered heterogeneous spatial structure. The onset of ore-forming processes marks the transformation of spatial distribution structures of the elements.Taking uranium grade as an order parameter and using the evolving equation of uraniummineralization and the dissipative structure theory, the author describes the evolution of the uranium mineralization system and the conditions for uranium mineralization. It is also pointed outthat araninization is not only closely related to geochemical conditions, but also fo antocatalysisand coherence effects of long-range transportation.
