Several recognizable sand-body types which yield hydrocarbons are associated with each of these deltas.(3) Very fine- to fine-grained sandstone and siltstone with abundant ripple cross bedding (Sr), graded bedding and more locally, muddy sandstones affected by soft-sediment deformation (Sd), and chaotically deformed beds (Fig. 4 I). In general, these fine-grained sandstones and dark colored mudstones (Fc or Fb) can exhibit a coarsening …Nov 1, 1989 · Along with this, some other terms are replaced with names having more relevance to the appearance of the rock. For instance, the name "slightly gravelly muddy sandstone" is replaced by "muddy sandstone with dispersed clasts". Names, with their abbreviations, are given in Fig. 2 where the second modification becomes im- mediately obvious.
