As for the inner shelf laterallycontinuous sedimentary prism, it probably represents sedimentary elements of sq5 that developed under sealevel highstand conditions, resulting in a wedgelike feature whose external limit roughly coincides with the 50 m isobath figs 2 and 6a. Formations are not defined by the thickness of their rock strata. The sedimentary structures which result are roughly horizontal units composed of inclined layers. Geology is the study of the earths structure, surface, and origins. The original depositional layering is tilted, such tilting not being the result of postdepositional deformation. The profile indicates that the om deposition was interrupted a number of times by the deposition of sandy sediments.
