Abstract
This thesis collected sedimentological information such as sedimentary structures, biological indicators, erosional information, grain size distribution, etc., from articles documenting tide-dominated and -influenced deltas. For an article to be included it must directly interpret a tide-dominated or tide-influenced delta, separate the information into subenvironments, and present sedimentological information to a degree of completeness. This information was recorded into a dataset and analyzed to present a quantitative description of the reported variability in tide-dominated and -influenced deltas throughout the literature. The results show little consistency in the reported sedimentary characteristics for each subenvironment, but some sedimentary structures and tidal indicators are reported consistently somewhere in of tide-dominated and -influenced deltas. The results of this thesis can be referenced by other researchers when interpreting tide-dominated and -influenced deltas. The results also lead to suggestions on what should be added to future tide-dominated and -influenced delta models to aid researchers in the field. The end of this paper consists of suggestions based on lessons I learned throughout this thesis for researchers that would like to conduct a similar study. I then suggest plans to create a quantitative “grand database” comprised of sedimentological information for all interpreted outcrops. This “grand database” provides data for accurate quantitative analysis of sedimentological data.
