Comments on Geologic Parameters

16 Rock Mineralogy:

In cores and cuttings of the Mt. Simon sandstone in the subsurface of Michigan and from outcrops in adjacent areas, the rock is a feldspathic quartzose sandstone, and most is arkose. "Many of the quartz and feldspar grains have authigenic overgrowths of secondary-mineral cement." (Briggs, 1968; p.141). However, one should keep in mind that Briggs had a very small data set to choose from. The outcrop observations of Driese and others (1981) (that the Mt. Simon is a quartz arenite) must be taken into account as well. Nonetheless, Briggs (1968) provided a table of rock mineralogy from the Consumers Power Company Brine Disposal No. 139, and we have included it in our analysis.
