They conventionally are subdivided into categories based on mode of genesis. Structures that are produced at the same time as the sedimentary rock in which they occur are called primary sedimentary structures. Sedimentary structures include all kinds of features in sediments and sedimentary rocks, formed at the time of deposition .
