That exposed karst is a general term for bare karstic rocks outcropping at the surface of the ground. it embraces karst areas without any initial cover (naked karst) or exposed by erosion of the residuum and soil (denuded karst) or of the allochthonous cover (exhumed karst) [20]. karst topography in which cover is absent [17]. synonyms: (french.) karst expose; (german.) nackter karst, oberflachlicher karst, wiederaufgedeckter karst; (greek.) akalypton karst; (italian.) carso denudato; (russian.) goly karst, otkryty karst; (spanish.) karst subaero; (turkish.) belirgin karst; (yugoslavian.) ljuti krs. see also denuded karst; exhumed karst; naked karst.?

Outcrop analog for Trenton–Black River hydrothermal dolomite reservoirs, Mohawk Valley, New York
Abstract:

Geochemical analysis and field relations of linear dolomite bodies occurring in outcrop in the Mohawk Valley of New York suggest that the area has undergone a significant faultrelated hydrothermal alteration. The dolomite occurs in the Lower Ordovician Tribes Hill Formation, which is regionally a Lower Ordovician shaley limestone with patchy dolomitization. The outcrop has an en echelon fault, fracture, and fold pattern. A three-dimensional (3-D) ground-penetrating radar (GPR) survey of the quarry floor has helped to map out faults, fractures, anticlines, synclines, and the extent of dolomitization. Most of the dolomitization occurs in fault-bounded synclines or sags flanked by anticlines. The dolomite structures are highly localized, occurring around faults, and are absent away from the faults and fractures. Trenches cut across the outcrop help relate offset along faults to the overall geometry of the dolomitized bodies. Geochemical analysis, although helpful in characterizing the conditions of dolomitization, does not define its origin absolutely. This study uses fluid inclusions, stable isotopes, 3-D GPR, core analysis, and surficial observations, which all show a link between faulting, dolomitization, and other hydrothermal alteration. Although the outcrop is much too small and shallow to act as a producing gas field, it serves as a scaled analog for the Trenton–Black River hydrothermal dolomite reservoirs of eastern United States. It may therefore be studied to help petroleum geologists characterize existing gas plays and prospect future areas of exploration.
