<DIV STYLE="text-align:Left;"><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>The Oriskany Sandstone is overlain by a cherty Onadaga Limestone and/or the Needmore Shale (Oliver and others, 1967; Milici, 1996). This interval is somewhat effective as a top seal, but it may be permeable in areas because of fracturing. However, the Onadaga Limestone/Needmore Shale interval is overlain by a thick section of Middle Devonian black shale, which makes an excellent regional confining layer. For the GIS, we chose the map of Oliver and others (1967; their fig. 8), which shows the distribution of lithologies of the Middle Devonian black-shale sequence. This sequence is widely interpreted to be laterally continuous, deep-water black shales (Oliver and others, 1967; Roen and Walker, 1996). </SPAN></SPAN></P><DIV><P><SPAN /></P></DIV></DIV> |
