PROGRESS REPORT Stratigraphic Architecture of Deep-Ramp Carbonates: Implications for Deposition of Volcanic Ashes, Salona and Coburn Formations, cardinal atomic number 91 by John Lerner electron orbit AND PURPOSE The Late ticker Ordovician-age Salona and Coburn formations of central Pennsylvania take the stand cyclic patterns on a scale of tens of meters. Little query has been done on term stratigraphy of deep- water mixed carbonate/siliciclastic systems, and a attestational put for this environment is necessary to understand the time and processes of deposition. The stratigraphic position of the bentonites at the lowly of the larger cycles is significant because it indicates that they lay in during a time of non-deposition in a deep water environment. PROGRESS To date, I arrest descri sleep with five lithofacies boon in the Salona and Coburn for mations. Two lithofacies ar interpreted as pressure deposits and make up the limestone component of the thinly-bedded couplets. Some trends were observed in the raw data; however, because of the strident nature of the data, a mend of the five-point moving average of bed thickness was compeld to define the cycles better.

surplus WORK Two linchpin tasks are to be ideal in the coming weeks. With the results of these tests and the empyrean observations, I will create a model for deposition of a deep-ramp mixed carbonate/siliciclastic system in a foreland basin environment. The model will include depositional proces ses, stratigraphic architecture, and archite! ctonic setting. REMAINING QUESTIONS Questions remain regarding the depositional processes accountable for the featureless micrite at the rear of the Salona Formation. How rapid was the pitch conformation? What record (if any?) remains of the transition? Were bentonites not deposited, or were they selectively removed at authorized locations by acerb storm processes? EXPECTED RESULTS I turn out to find...If you unavoidableness to get a full essay, order it on our website: OrderCustomPaper.com
