Abstract or Summary
  • The thesis area consists of 65 square miles located in the southeastern part of Meagher County, Montana. Ranging in age from Precambrian to Quaternary, the strata exposed in the area have a total thickness of about 11,100 feet. Low grade metamorphic rocks, mainly slates, and limestones represent the estimated 2,000 foot thick Precambrian unit. Paleozoic rocks, about 2,600 feet in thickness, consist mainly of carbonates but include marine sandstones, some of which were metamorphosed into quartzites. Ordovician, Silurian, and Permian strata are absent. The Mesozoic rocks are dominantly marine, continental, and lacustrjne sandstones, siltstones, and shales. Rocks of Triassic age are not present in this 6, 500 foot thick sequence of sedimentary rocks. Intrusive and extrusive igneous rocks, glacial deposits, and unconsolidated alluvium represent the Cenozoic Period. The major structures in the thesis area are the result of the Lararnide Revolution and date from Late Cretaceous to Early Tertiary.
