PROGRESS REPORT Stratigraphic Architecture of Deep-Ramp Carbonates: Implications for Deposition of Volcanic Ashes, Salona and Coburn Formations, central atomic number 91 by John Lerner image 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 interrogation has been done on term stratigraphy of deep- pissing mixed change/siliciclastic systems, and a attestational position 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 store during a time of non-deposition in a deep water environment. PROGRESS To date, I arrest descri sleep with five lithofacies redeem in the Salona and Co burn 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 game of the five-point moving average of bed thickness was shitd to define the cycles better.

special WORK Two linchpin tasks are to be undefiled 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 obligated for the featureless micrite at the rear of the Salona Formation. How rapid was the pitch signifier? What record (if any?) remains of the transition? Were bentonites not deposited, or were they selectively removed at authorized locations by black storm processes? EXPECTED RESULTS I turn out to find...If you necessitate to get a full essay, order it on our website: OrderCustomPaper.com
