【Abstract】 The dissipative structure is an ordered structure. When a system is far away from state of equilibrium in the condition of nonequilibrium and interchanges some energy and material with outside circumstances, this structure will be formed and maintained. Starting from analysing practical data, we attempt to use this theory, and discuss the tectono-geochemical problem of some rock and ore formation systems in faults.1. Ordered structure. In the geological condition, this is due to the open system in which there are energy and material in geochemical action, so that the entropy gradually tends to reduce and substance get to evolved from non-order to ordered structures. In the process of rock and ore formation in faults, various layer-bands and layer-levels will be formed in rock material.2. Functional action: The activities of physics-chemistry which include a pressure-creeping and thermal-diffusing as well as liquid over-flowing have been shown. 3. Fluctuating cycIe: In the process of metamorphism of rock and ore formation in faults, various changes of pressure, temperature and liquid show a fluctuating wave and periodic cycle. This plays an important part in the occurrence of rock and mineral and the formation of ordered structures in fault zones.4. The above-mentioned ordered structure, functional action and fluctuating cycle are mutually related to each other as following correlogramFinally, we have cited a few examples of mineral deposits in the middle and lower reaches of the Yangtse River, and the dissipative activities of rock-forming minerals and mineral-forming elements have been preliminarily established.更多还原
