PROGRESS REPORT Stratigraphic Architecture of Deep-Ramp Carbonates: Implications for Deposition of Volcanic Ashes, Salona and Coburn Formations, primaeval atomic number 91 by John Lerner image AND PURPOSE The Late ticker Ordovician-age Salona and Coburn formations of central Pennsylvania furnish cyclic patterns on a scale of tens of meters. Little look has been done on term stratigraphy of deep- water mixed change/siliciclastic systems, and a attestational determine for this environment is necessary to understand the measure 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 place in the Salona and Coburn formations. Two lithofacies ar interpreted as pull 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 eyepatch of the five-point moving average of bed thickness was acquired to define the cycles better.

extra WORK Two linchpin tasks are to be finish 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 proc esses, stratigraphic architecture, and archi! tectonic setting. REMAINING QUESTIONS Questions remain regarding the depositional processes trustworthy for the featureless micrite at the rear of the Salona Formation. How rapid was the pitch course? What record (if any?) remains of the transition? Were bentonites not deposited, or were they selectively removed at authorized locations by acerbic storm processes? EXPECTED RESULTS I turn out to find...If you essential to get a full essay, order it on our website: OrderCustomPaper.com
