متن کاملConodonts and Biostratigraphy of Upper Ordovician Strata along a Shelf to Basin Transect in Central Nevada
Conodonts representing 38 species of 26 genera have been identified in samples from Upper Ordovician rocks at three central Nevada localities. Ranges of these species and associated graptolites are used graphically to determine correlation of the strata considered with an evolving composite standard that includes information from Ordovician strata at more than 100 localities in North America. R...
متن کاملMagnetostratigraphy susceptibility of the Upper Ordovician Kope Formation, northern Kentucky
As a test of the utility of magnetic susceptibility (MS) measurements for correlation among lithified marine sequences, samples were collected from well-studied shale and limestone outcrops of the Upper Ordovician Kope Formation, northern Kentucky. The bulk (initial) low-field MS of these samples is compared among two lithoand biostratigraphically correlated sections containing the same beds. T...
متن کاملThe Geology of Ohio--the Ordovician
To geologists, the Ordovician System of Ohio is probably the most famous of the state's Paleozoic rock systems. The alternating shales and limestones of the upper part of this system crop out in southwestern Ohio in the Cincinnati region and yield an incredible abundance and diversity of well-preserved fossils. Representatives of this fauna reside in museums and private collections throughout t...
