Origin and stratigraphic significance of limestone discontinuity surfaces, Ordovician (Whiterockian) of Nevada

Results indicate that discontinuity surfaces enhance correlations between sections only after a well-established biostratigraphic zonation is in place. Chronostratigraphically significant discontinuities parallel biozone boundaries or occur in roughly equivalent abundances within zones. Diachronous surfaces may demonstrably converge into single discontinuity surfaces in other sections. Diachronous surfaces appear, in part, to be a function of topographic irregularities within the depositional system.
