Description : In eastern North America, the Late Ordovician was a time of marked changes in both the tectonic setting and in paleo-oceanographic conditions at the margin of Laurentia. The rapidly foundering of the warm- to ultimately cool-water like carbonate ramp was succeeded by organic matter rich black shales, a past target for shale gas development, and overlying flysch.

The fieldtrip will examine the rapid facies, faunal and geochemical evolution from warm-water to cool-water like carbonate facies. The field trip will also address the transition from the carbonate ramp to a deep fine-grained clastic succession.
