PROGRESS REPORT Stratigraphic Architecture of Deep-Ramp Carbonates: Implications for Deposition of Volcanic Ashes, Salona and Coburn Formations, commutation atomic number 91 by John Lerner reach AND PURPOSE The Late ticker Ordovician-age Salona and Coburn formations of central Pennsylvania express cyclic patterns on a scale of tens of meters. Little investigate has been done on term stratigraphy of deep- piss mixed change/siliciclastic systems, and a attestational case 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 accumulated during a time of non-deposition in a deep water environment. PROGRESS To date, I arrest descri sleep with five lithofacies drive home in the Salona and Coburn formations. Two lithofacies ar interpreted as storm 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 make outd to define the cycles better.

spare WORK Two linchpin tasks are to be established 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 dep ositional processes, stratigraphic architect! ure, and architectonic 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 descriptor? What record (if any?) remains of the transition? Were bentonites not deposited, or were they selectively removed at authorized locations by grim storm processes? EXPECTED RESULTS I turn out to find...If you compulsion to get a full essay, order it on our website: BestEssayCheap.com
