摘要
极低级变质作用是指变质作用最低级的部分，包括成岩作用和浅层变质作用，其变质温度范围大体介于１５０～３７０℃之间。本文简要地对极低级变质作用和极低级变质带的特征和研究领域进行综述，可以看出，通过极低级变质作用和极低级变质带的研究，能够提供造山带、沉积盆地演化及板劈理发育等有关地球动力学过程和流变状态信息；强调指出进一步研究极低级变质作用和极低级变质带的必要性。
Very-low-grade metamorphism,including high-grade diagenesis and anchimetamorphism,is used in this paper for the lowest grade of metamorphism in the approximatetemperature range of 150 to 370℃.The very-low-grade metamorphism and metamorphicbelts have been intensively studied by many workers.General features and fields of study ofthe very-low-grade metamorphism and metamorphic belts are briefly reviewed.The studiesmay provide a body of information on the rheological conditions for orogenic process,sedimentary basin and cleavage development.It is argued that further research on the very-low-grade metamorphism and metamorphic belts would be worthwhile.
