Abstract

One of the goals of science is to create order out of apparent disorder. Inherent in this pursuit is the need to classify and subdivide naturally occurring phenomena in order to better understand their origin. Stratigraphers since at least the early 20th century have sought to divide lithologic successions into genetic sequences. In regard or application to carbonate strata, stratigraphers have approached this goal from two general perspectives.

One group has emphasized the significance of the areal distribution of strata and the nature of their bounding surfaces. Blackwelder in 1909 expounded on a scheme showing the areal distribution and ages of unconformity-bounded, Phanerozoic sequences of a part of the central United States. Sloss (1963) widened the scope of this endeavour and provided a division of Phanerozoic strata over the cratonic interior of North America into six unconformity-bounded sequences. Explicit in both schemes was the recognition that unconformities are of a long duration toward the centre of the craton and disappear into conformable successions along cratonic margins. The utility of Sloss Sequences has gained wide acceptance and has been used as a means for discussing the Phanerozoic evolution of sedimentary basins, for example the Western Canada Sedimentary Basin (Ricketts, 1988).
