| 520 | 3 |a"Four boreholes which were drilled 25 to 50 m apart at a field site, in the Niagara Falls, New York region, were used to examine the nature of the fracture permeability in the Lockport dolostone. The Lockport Group is a sequence of dolostone formations of Upper Silurian age which make up the upper bedrock in the Niagara Falls region. The study was conducted to evaluate the use of standard packer separations in determining the permeability of a bulk rock mass which is pervaded by fractures at a frequency greater than the packer spacing"--Abstract. |
