PROGRESS REPORT Stratigraphic Architecture of Deep-Ramp Carbonates: Implications for Deposition of Volcanic Ashes, Salona and Coburn Formations, of import atomic number 91 by John Lerner place setting AND PURPOSE The Late ticker Ordovician-age Salona and Coburn formations of central Pennsylvania video display 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 baby-sit for this environment is necessary to understand the quantify and processes of deposition. The stratigraphic position of the bentonites at the lowly of the larger cycles is significant because it indicates that they put in during a time of non-deposition in a deep water environment. PROGRESS To date, I arrest descri sleep with five lithofacies defer in the Salona an d Coburn formations. Two lithofacies ar interpreted as fall upon 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 plot of ground of the five-point moving average of bed thickness was take ind to define the cycles better. supernumerary WORK Two linchpin tasks are to be entire 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 processes, stratigraphic architecture, and architectonic setting. REMAINING QUESTIONS Questions remain regarding the depositional processes answerable for the featureless micrite at the rear of the Salona Formation. How rapid was the pitch mannequin? What record (if any?) remains of the transition? Were bentonites not deposi ted, or were they selectively removed at au! thorized locations by caustic storm processes? EXPECTED RESULTS I turn out to find...If you pauperization to get a full essay, order it on our website:
