Sedimentary Structures and Textures
Sedimentary structures and textures refer to the physical features and arrangements of sedimentary rocks that provide information about the conditions in which they were deposited. These structures and textures can provide important clues about the nature of the depositional environment, the nature of the sediment transport process, and the history of the sedimentary basin. They are used by geologists to interpret the history and evolution of sedimentary deposits. Sedimentary structures can range in scale from millimeters to meters or more, and include features such as bedding planes, cross bedding, ripple marks, mud cracks, and fossils, among others. Sedimentary textures refer to the size, shape, sorting, and arrangement of sediment grains, and can include features such as grain size, shape, and orientation, as well as sorting and packing of the grains within the sedimentary rock.
