北京西山流变构造性质的鉴定——兼论固态流变构造与同沉积构造的区别

iDENTIFICATION OF THE NATURE OF RHEOMORPHIC STRUCTURES IN THE WESTERN HILLS,BEIJING——WITH A DISCUSSION OF THE DIFFERENCE BETWEEN SOLID-STATE STRUCTURE AND SYNSEDIMENTARY STRUCTURE

摘要: 文章对北京西山一带,中元古界至下古生界沉积岩系中的粘塑性流动变型构造,从实际资料出发,论证其成因类型,并进而提出固态流变构造与同沉积构造的区别标志。

Abstract: In this paper the attributes of the rheomorphic structures are for the first time dealt with in details and the general features of synsedimentary deforma- tion structures both at home and abroad are summarized systematically.Thro- ugh comparison,nine.applicable criteria for distinguishing rheomorphic stru- ctures from synsedimentary deformation structures are proposed.
