摘要：

岩石流变作用是大陆造山作用的基本特征，超高压岩石的形成和折返过程也是大陆深俯冲带内物质的复杂流变过程。要深入理解大陆造山带的造山作用和大陆壳岩石的深俯冲和折返动力学过程，必须对大陆地壳及地幔岩石的流变学进行深入研究。岩石圈流变学的主要研究内容主要包括流变学分层性、变形分解和应变局部化及大陆壳岩石部分熔融作用的流变学效应等。应用岩石圈流变学的基本原理和方法，分析了大别—苏鲁超高压变质带中超高压变质岩的塑性流变特点，探讨了超高压变质岩形成和折返过程的塑性流变学。

关键词: 超高压变质岩, 塑性流变学, 大别—苏鲁超高压变质带

Abstract:

Rheology of rocks is an essential characteristics for continental orogenesis. The formation and exhumation of the UHP metamorphic rocks is a complex rheological process for the material in deep subduction zone. A profound study on the rock rheology of continental crust and mantle is a key to comprehensively understand of the continental orogenesis and dynamic process of deep subduction and exhumation of the continental crustal rocks. Lithosphere rheology mainly concerns about the rheological stratification, deformation partitioning and strain localization, and the effect of partial melting on the rheology of the continental crustal rocks. Based on the essential principle and method of the lithosphere rheology, the rheological properties of the UHP metamorphic rocks in the DabieSulu UHP metamorphic belt are described and the plastic rheology of the formation and exhumation process of the UHP metamorphic rocks are discussed.

Key words: ultrahigh-pressure metamorphic rock, plastic rheology, Dabie-Sulu UHP metamorphic belt
