Geochemical analysis and field relations of the Palatine Bridge dolomite outcrop in the Mohawk Valley of New York suggest that it has undergone significant fault-related hydrothermal diagenesis. This study focuses on fluid inclusion, stable isotope, 3D-Ground penetrating radar, core analysis, and surficial observation which all show a link between faulting, dolomitization, and other hydrothermal alteration. It is a scaled analog for Trenton / Black River hydrothermal dolomite reservoirs of the eastern United States. The outcrop is in the Lower Ordovician Tribes Hill Formation, which is an early Ordovician shaley limestone.
