COMPARATIVE PETROGRAPHIC, ·PETROCHEMICAL AND SPECTRO GRAPHIC ANALYSES OF THE PRECAMBRIAN GRANITIC ROCKS OF SOUTHEASTERN MISSOURI BY EVA BOGNAR KISVARSANYI A THESIS submitted to the faculty of the SCHOOL OF MINES AND METALLURGY OF THE UNIVERSITY OF MISSOURI in partial fulfillment of the work required for the Degree of MASTER OF SCIENCE, GEOLOGY MAJOR Rolla, Missouri 1960 -12au&a4AM~ (advisor) £tg~¥Ni ii ABSTRACT Petrographic, petrochemical and spectrographic studies were completed on selected Precambrian granitic rock samples from South eastern Missouri. This investigation contributes to a more detailed knowledge of the Precambrian granitic rocks of this part of the state. Petrographic analysis of forty-four thin sections of granitic rocks from the St. Francois Mountains area revealed six different granite types. These have been named the Fredericktown, Knoblick, Doerun, Graniteville, Klondike and Silvermine granites. These rocks form a large part of a composite batholith.
