The Trenton Group (Upper Ordovician Series) of Eastern North America: Deposition, Diagenesis, and Petroleum

Regional facies for the Upper Ordovician Series (global classification) of eastern North America consist of clean (pure) carbonates, mixed carbonates and terrigenous clastics, shale, terrigenous clastics coarser than shale, and terrigenous clastics prograding over carbonates. The last facies is characteristic of the Upper Ordovician. Maps and cross sections for stages of the Upper Ordovician demonstrate the influence of regional tectonic events on the sedimentation pattern of these facies.
Bioclastic Turbidites in the Trenton Limestone: Significance and Criteria for Recognition

Published:January 01, 1988
Abstract
The Denley Limestone (Trenton Group) in the Mohawk Valley, New York, is composed of bioclastic turbidites associated with slump fold horizons and syndepositional block faults which indicate that the limestones of the Denley Formation are foreland basin/trench slope deposits.
