摘要
本文提出了加强变质岩区中大比例尺填图工作中构造研究的五条建议,主要包括正确理解和运用构造解析方法,学习现代构造理论,深刻认识地壳流变学分层性、变形分解及各种面线构造的物理意义.指出了当前对一些变质岩构造概念理解上的错误倾向.强调构造解析的目的是建立构造热事件过程中岩石的几何学、运动学、动力学和流变学模式,因之,变形岩石流变学和变形物理条件的详细观察研究,是极为重要的.
Included in this paper are five suggestions on structural study during regional geological survey or geological mapping in metamorphic rock areas with special regard to the structural analysis methods,advanced tectonic theories,rheological stratification deformation partitioning,a variety of foliation and lineation structures and their physical significance. At the same time, attention is drawn to the increasing misunderstandings of the communication of data and concepts which were involved in the metamorphic structure geology. It is emphasized that a fundamental aim of structural analysis is to establish the geometries,kinematics,dynamics and rheology of metamorphic rocks during tectonic-thermal events. The detailed observation of deformation rock rheology and physical conditions is an important element in such analysis and field mapping.
