He organized the SEPM Research Symposium on Sedimentary Structures in Toronto, ( 1964 ) and SEPM s first Short Course ( on turbidites, Anaheim CA, 1973 ).

Sedimentary structures such as cross bedding, graded bedding and ripple marks are utilized in strata in geologically complex terrains and understand the depositional environment of the sediment.
33.
It is also used for the sandstone sedimentary structure rock formations that were produced by this process in an earlier geologic era, such as the Cretaceous Period.
34.
In addition, sandstone beds associated with the Gillespie Lake Member seem similar to microbially induced sedimentary structures ( MISS ) found on Earth, according to one study.
35.
It is predominantly composed of mature, poorly cemented quartz sandstone, though several distinct facies have been identified on the basis of grain size, feldspathic content, and sedimentary structures.
36.
Sedimentary structures, for example those produced by empty shells rolling along the sea floor, are not produced through the behaviour of an organism and not considered trace fossils.
37.
Its grain sizes are mainly coarse sand and medium sand, which are larger than that in littoral barrier dune . The sedimentary structures include parallel bedding and low-angle cross-bedding.
38.
In geology, "'ripple marks "'are sedimentary structures ( i . e . bedforms of the lower flow regime ) and indicate agitation by water ( waves ) or wind.
39.
The sedimentary structures in the upper member of the Nankoweap Formation are interpreted to indicate that it accumulated beneath moderate-to low-energy, shallow waters, either in a shallow sea or lake.
40.
Each layer described by Bouma has a specific set of sedimentary structures and a specific lithology ( see below ), with the layers overall getting finer-grained from bottom to top.
