These veins formed by the polymerization and solidification of hydrocarbons that were mobilized from the deeper oil shales of the Green River Formation during burial and diagenesis.
32.
This has been proposed as an explanation for lower than expected C / N signatures of organic carbon in sediments that have undergone post-depositional diagenesis.
33.
The study of diagenesis in rocks is used to understand the geologic history they have undergone and the nature and type of fluids that have circulated through them.
34.
Post-depositional diagenesis occurs in organic-carbon-poor marine sediments where bacteria are able to oxidize organic matter in aerobic conditions as an energy source.
35.
This is a form of diagenesis . " This reads to me like actual teeth would not last over 65 million years, but be replaced by minerals.
36.
The mineral probably formed from diagenesis of chlorophyll, likely chlorophyll " a ", which was transported as an aqueous solution into a favorable geologic setting.
37.
However, if at least a few remnants of an organism make it to final burial, a fossil may eventually be formed unless destruction is completed by diagenesis.
38.
The term diagenesis is used to describe all the chemical, physical, and biological changes, exclusive of surface weathering, undergone by a sediment after its initial deposition.
39.
His fields of interest are sequence stratigraphy, carbonate sedimentology, diagenesis, stratigraphy, rock-typing and micropaleontology ( particularly on the study of fossil calcareous algae ).
40.
This confirmed Brain s earlier work that skeletal element representation patterns were more likely generated from factors relating to the resilience of bone to weathering, carnivore damage and diagenesis.
