白垩纪若干重大地质事件的耗散结构分析

应用耗散结构理论对白垩纪若干重大地质事件进行了分析,认为海底火山作用的发生和演化是一个动力学过程,海底火山的非平衡定态失稳是在非平衡态下宏观体系的自组织现象具体表现;大洋缺氧事件发生是同位素的共生组合、赋存状态和分散状态在特定条件下开放地球化学系统所处的非平衡定态的质和量的局域扰动触发定态失稳的结果;超静磁带事件意味着地球核幔相互作用和外核流体运动可能处于能量最低的状态,地球磁场系统通过不断地与外界交换物质和能量,维持一种空间或时间的有序结构.这种结构为系统发生能量耗散所致.

An analysis of the dissipative structure of several Cretaceous major geological events

Dissipative structure theory has been used to analyze the Cretaceous several major geological events. The occurring and evolving of seafloor volcanism is considered a dynamic process and the nonequilibrium stationary state breaking-steadying of seafloor volcanoes represents the self-organization phenomena of the macroscopical system under non-equilibrium state. Oceanic anoxia events arise from the intergrowth compounding, accumulating and dispersing states of isotopes under a special condition and from that the partial disturbance of qualities and quantities of non-equilibrium stationary state spring the stationary state breaking-steadying in an opening geochemistry system. Cretaceous Normal Superchron implies that the interaction of earth core-mantle and liquid movement in the outer core may be the lowest energy state and the earth magnetic field system maintains a sort of temporal or spatial order structure by exchanging substance and energy in the outside continuously. This structure is caused by energy dissipating of system.
