"This thesis deals with stylolites, slump structures, sulfides in the oolitic limestone, and geometry of the bedded fluorite deposits in the Cave-In-Rock fluorspar district, southern Illinois. Stratigraphic zones studied were: 1) the upper part of the lower Fredonia limestone member, 2) the upper part of the upper Fredonia limestone member,,and 3) the upper part of the Renault formation.
Geometry of the ore rocks and related structures was investigated. Most of the ore is layered and constitutes part of the sedimentary strata.
Slump structures were observed and studied in detail. Most of the slump structures show evidence which indicates a sedimentary origin.
An extensive review was made of previous investigations of stylolites. Particular attention was given to the genetic criteria.
Megascopically, the stylolites are classified into the six basic patterns. Relationships of stylolites to individual rock grains are defined and classified. Aggregate stylolites were defined as those which have amplitude larger than the rock grain diameters; intergranular stylolites have an amplitude less than the grain diameter.
Detailed megascopic observations on the stylolites and related sedimentary structures and extensive microscopic study suggest that the stylolites were formed during compaction of semi-plastic sediments.
Detailed microscopic observations of the sulfide-wall rock relationships in the lower Fredonia limestone indicate a sedimentary origin of the sulfide"--Abstract, page v.
