“…The d 18 O values measured for the Cantabrian dolomites are comparable with those of late burial dolomites reported in literature(Mattes and Mountjoy, 1980;Taylor and Sibley, 1986;Barnaby and Read, 1992;Spencer-Cervato and Mullis, 1992;Coniglio et al, 1994;Morrow and Aulstead, 1995;Nielsen et al, …”

“…Some hydrothermal dolomites have been interpreted to result from thermal convection of normal seawater (Wilson et al, 1990;Spencer-Cervato and Mullis, 1992 deep residual brines derived from seawater evaporation (Morrow et al, 1990;Morrow and Aulstead, 1995;Wendte et al, 1998); the brines descended through fractures and were modified during burial. A similar model was proposed by Coniglio et al (1994) to explain dolomitization in Ontario. In all these examples the convective circulation of fluids was promoted by increased heat flow from the basement.…”

“…It is beyond the length limits of this article to review these in detail. They include the topographic recharge model of Garven and Freeze (1984;applied by Montañ ez, 1994;Mountjoy, 1992, 1994;Yao and Demicco, 1995), the tectonically driven compaction-flow model (Oliver, 1986; applied variably by Amthor et al, 1993;Qing and Mountjoy, 1994;Drivet and Mountjoy, 1997), burial compaction and dewatering of shales (Machel and Mountjoy, 1987, and others), the mixed water aquifer-flow model (Badiozamani, 1973), regional seepage reflux (King, 1947;Adam and Rhodes, 1960;Brady, 1995, 1996;Jones et al, 2003), and thermal convection circulation (Evans and Nunn, 1989;Coniglio et al, 1994;applied by Yao andDemicco, 1995, 1997;Morrow, 1998;Demicco and Spencer, 2004;Morrow and Aulstead, 2004).…”

“…In most respects, the dolomitized zones look the same with matrix dolomitization, breccias, saddle dolomite, fractures and vugs and the clear link to faults. At the Hillman Field in Ontario, fluid inclusion homogenization temperatures for the dolomites ranged from 100-220°C (Coniglio et al, 1994), but CAI analysis in that area suggests that the Trenton was never buried more than a kilometer (Colquhoun, 1991). Using a geothermal gradient of 25-30°C/km and a surface temperature of 20°C, the maximum burial temperature was 45-50°C.…”

The Trenton-Black River Appalachian Basin Research Consortium has made significant progress toward their goal of producing a geologic play book for the TrentonBlack River gas play. The final product will include a resource assessment model of Trenton-Black River reservoirs; possible fairways within which to concentrate further studies and seismic programs; and a model for the origin of Trenton-Black River hydrothermal dolomite reservoirs.All seismic data available to the consortium have been examined. Synthetic seismograms constructed for specific wells have enabled researchers to correlate the tops of 15 stratigraphic units determined from well logs to seismic profiles in New York, Pennsylvania, Ohio, West Virginia and Kentucky. In addition, three surfaces for the area have been depth converted, gridded and mapped. A 16-layer velocity model has been developed to help constrain time-to-depth conversions. Considerable progress was made in fault trend delineation and seismic-stratigraphic correlation within the project area.Isopach maps and a network of gamma-ray cross sections supplemented with core descriptions allowed researchers to more clearly define the architecture of the basin during Middle and Late Ordovician time, the control of basin architecture on carbonate and shale deposition and eventually, the location of reservoirs in Trenton Limestone and Black River Group carbonates. The basin architecture itself may be structurally controlled, and this fault-related structural control along platform margins influenced the formation of hydrothermal dolomite reservoirs in original limestone facies deposited in high energy environments. This resulted in productive trends along the northwest margin of the Trenton platform in Ohio. The continuation of this platform margin into New York should provide further areas with good exploration potential.The focus of the petrographic study shifted from cataloging a broad spectrum of carbonate rocks that occur in the Trenton-Black River interval to delineation of regional limestone diagenesis in the basin. A consistent basin-wide pattern of marine and burial diagenesis that resulted in relatively low porosity and permeability in the subtidal facies of these rocks has been documented across the study area. Six diagenetic stages have been recognized: four marine diagenesis stages and two burial diagenesis stages. This dominance of extensive marine and burial diagenesis yielded rocks with low reservoir potential, with the exception of fractured limestone and dolostone reservoirs. Commercial amounts of porosity, permeability and petroleum accumulation appear to be restricted to areas where secondary porosity developed in association with hydrothermal fluid flow along faults and fractures related to basement tectonics.A broad range of geochemical and fluid inclusion analyses have aided in a better understanding of the origin of the dolomites in the Trenton and Black River Groups over the study area. The results of these analyses support a hydrothermal origin for all of th...
