摘要
系统总结了上部地壳环境中方解石质岩石的浅成流动机制与低温糜棱岩成因研究的几个重要方面 :( 1)地壳岩石脆 -韧性转变域与岩石变形机制 ;( 2 )变形作用过程中流体相的物理与化学意义 ;( 3)方解石质岩石的流动机制、变形特点与蠕变规律。同时讨论了对于地壳浅部层次方解石质岩石流变学研究中存在的主要问题以及解决这些问题的基本思路与科学意义。
Several major aspects on the flow of calcite rocks in the upper crust level and on the genesis of low temperature mylonites are reviewed: (1) The brittle to ductile transition and the mechanisms of rock deformation in the transition; (2) the physical and chemical effects of fluid phases during low temperature deformation; (3) the flow mechanisms of calcite rocks, the characteristics of deformation and the creep mechanisms of such rocks. The scientific significance of some problems open to further discussion and possible ways of study are discussed.
