Sedimentary Structures: • Features in sedimentary rocks that reflect depositional or diagenetic processes. – Diagenesis: • physical and/or chemical changes to sediments following deposition and up to metamorphism.
Abstract. The authors do not know of any serious attempt to classify all sedimentary structures. Several partial classifications, however, have been proposed. Most important are those which deal primarily with bedding. The most comprehensive of these are those of Andree (1915), Hoppe (1930), Andersen (1931),
Sedimentary structures that formed sometime after the deposition, during burial diagenesis, are classified as secondary sedimentary structures (Potter and. Pettijohn, 1964). A complete review of primary sedimentary structures can be found in Pettijohn and Potter (1964); Conybeare and Crook (1968); Pettijohn,. Potter, and
the structures in environmental interpretation. We begin study by examining the most commonly used names for the major primary sedimentary structures. Primary struc tures are those formed at, or very shortly after, the time of sediment deposition. 5.2 CLASSIFICATION OF PRIMARY. SEDIMENTARY STRUCTURES.
21 Apr 2015 primary sedimentary structures. 1. Presented by: Salman Naseer and Ali Asghar Shahid Bahria University Karachi; 2. Definition: These are the structures that are formed by the sediment layers in the way they are deposited over each other. Classified on two approaches, one is morphologic, the other
sedimentary rocks (and certain extrusive igneous rocks) display layering and undulations of bedding caused by episodes of deposition and erosion. These features, created by the physical interactions of grains and fluid, are called primary sedimentary structures. They are the statements, some times complete but more often

The most prominent and widespread feature is the alternating sand/clay (now quartzite/phyllite) succession visible in most of the bedding types.

deposition, the directions of the currents which deposited the sediments. Secondary sedimentary structures are those that formed sometime after sedimentation. They result from essentially chemical processes, such as those which lead to the diagenetic formation of concretions. Primary sedimentary structures are divisible
