General IntroductionAt any point in its history, a sample of rock can be said to have "structure." Sedimentary rock, whetherhighly contorted or flat-lying and undisturbed, is characterized by fabric, texture, and tectonic setting.In a very basic sense, the structural features of rocks can be divided into those that preceded the onset ofdeformation-called sedimentary structures-and those that were the result of strain imposed by externalforces-structures of tectonic origin. Sedimentary structures are formed during (1) deposition and (2)diagenesis that is uninfluenced by diastrophism. Tectonic structures, in contrast, can originate both duringand after diagenesis and are, of course, the major subject of structural geology.The relationship between tectonism and diagenesis, however, is often complex, which sometimes makesthe distinction between the two types of structures difficult or artificial. Deformational forces often directlyinfluence the lithification of sediments, particularly in areas where deposition occurs in close proximity togrowing mountain belts. Observed structures may exhibit an unbroken progression from sedimentary totectonic in origin.Notice, however, that we use the term "external forces" to refer to the origin of tectonic features. This, itturns out, is a highly useful simplification that justifies the distinction between the two structural types. Theidea that tectonic stress is applied from without onto relatively passive sedimentary strata he
