| 摘 要： | 强调了后克拉通(地台)活化区在岩石圈四维时空呈阶段性形成与发展的历史—动力学属性,这是任何一种地球动力学假说对活化区动力学作出解释时不可回避的根本问题。结合活化区地质、地球物理和地球化学研究的新进展,阐述了与活化区动力学研究相关的4个问题:活化区历史—动力学属性的意义,活化区动力机制的主动式与被动式,活化区动力作用中的继承性和自主性和活化区成矿作用的动力学意义,提出了“矿石探针”的概念。

| Abstract: | It is emphasized that the attribute of history-dynamics of the lithosphere in the activated regions during the postplatform stage is of multistage in time and space.Some cruxes have to be answered for any hypothesis of the earth’s dynamics to explain the dynamics of mobilized areas.On the basis of recent study data on geology,geophysics and geochemistry from the activated regions,the authors demonstrated the followings key points:1)the significance of the attribute of history-dynamics in the mobilized areas; 2)the active one and passive type of dynamic mechanism in the activated regions; 3)the initiative and inheritance of dynamic mechanism in the activated areas; and 4)the dynamic significance of metallization in the mobilized regions.In addition,a term of“ores probe”was proposed in this paper. |
