Madison limestone

The hnal example in this set is from the Madison regional aquifer study by Plummer et al. (1990). The Madison Limestone aquifer occurs in Wyoming, Montana, and South Dakota. Plummer et al. (1990) utilized a combination of saturation index constraints, inverse modeling, and carbon...

Colorado, is hosted in folded and brecciated Mississippian dolomite, shale, sandstone and coal, which is in fault contact with Precambrian gneiss. The Precambrian gneiss is anomalously enriched in uranium, and a Mesozoic or Caenozoic age of mineralization in the Mississippian host rocks, formed by downward percolation of uraniferous groundwater from the adjacent Precambrian terrain, is inferred. Mineralization in the Pryor Mountains region, Montana, is hosted in karsts developed with the Mississippian Madison limestone and consists of uraninite-tyuyamunite grading up to 7% UsOg associated with clay minerals and silicified collapse breccias. A Caenozoic age of mineralization, under conditions similar to those of Pitch mine, is favoured.

The Selbome Marble in Table 5.1 consists of highly deformed and metamorphosed scapolite-bearing marbles interbedded with biotite schist and homfels that occur only at Cape Selbome and at the north side of Couzens Bay, both of which are located south of the mouth of the Byrd Glacier. The relation of the Selbome Marble to the Shackleton Limestone is uncertain because the two units are not in contact. Skinner (1964, 1965) suggested that the Selbome Marble is either a highly altered part of the Shackleton Limestone or is a marble-amphibolite complex of the Precambrian Nimrod Group. Stump (1980) who worked on the Shackleton Limestone at nearby Mount Madison favored the explanation that the Selbome Marble is a highly metamorphosed member of the Shackleton Limestone. 

Fig. 5.10a Mt. Madison (80°27 S, 160°02 E) is located on the south side of the mouth of the Byrd Glacier. Its north-facing slope contains three small cirques that are separated from each other by two bedrock spurs which are composed of the Shackleton Limestone of the Byrd Group. Fig. 5.10b The crest of the western spur contains an outcrop of pegmatite composed of spodumene, lepidolite, bismuthinite, and tourmaline (Faure and Felder, 1984). The spur on which the pegmatite is located is marked by an x.

Carbonate rocks also show a decrease of porosity under the influence of depth or overburden pressure, respectively. Brown (1997) analysed the influence of carbonate mineralogy, shale content, and fabric on the porosity versus depth correlation. For the study, argillaceous limestone, limestone, dolomitic limestone, and dolomite of the Mississippian Madison Group in the Williston...
