Western Michigan University, 1986 The Upper Keweenawan Jacohsville Formation source areas were mixed source terranes with dominant terrane types changing regionally in relative abundances of sediment contribution. Dominant source terranes were older sediments, including a weathered soil zone, Upper Keweenawan Freda Sandstone and other recycled sandstones; plutonic Pre- cambrian basement rocks;. Middle Keweenawan Portage Lake Volcanics; and the chlorite to staurolite grade metamorphic rocks and iron ranges of Michigan’s upper peninsula. Depositional environments of the formation's four facies types range from fluvial to deltaic/lacustrine. Sediments were in transport for a short distance, resulting in grain freshness and angularity, moderate sorting and preservation of unstable sediments. Rapid erosion and deposition caused rock immaturity, an abundance of fresh, coarse feldspars and a wide range of alteration in a single species of feldspar. Two major basins of deposition were partially separated by a plutonic to metamorphic terrane highland. Major source areas were to the south­ east of the western end of the outcrop belt and to the south of the eastern two-thirds of the outcrop belt. Reproduced with permission of the copyright owner.

Thanks go to Robert Havira (Western Michigan University) for help in technical areas and with photo­ graphy. I would also like to thank The Graduate College for their financial support. The Huron Mountain Club is deeply appreciated for allowing me access to, and lodging on, their beautiful tract of land. Special thanks to Tim and Lee Flaherty for their warm hospitality during my stay with them. My deepest appreciation goes to Karen, my wife, for her patience, moral support and love. Heartfelt thanks go to Lisa, our daughter, for all of the joy she provided us during this project. David Walter Lindsay ii Reproduced with permission of the copyright owner.

While the most advanced technology has been used to pho­ tograph and reproduce this manuscript, the quality of the reproduction is heavily dependent upon the quality of the material submitted. Pages in any manuscript may have indistinct print. In all cases the best available copy has been filmed. The following explanation of techniques is provided to help clarify notations which may appear on this reproduction. 1. Manuscripts may not always be complete. When it is not possible to obtain missing pages, a note appears to indicate this. 2. When copyrighted materials are removed from the manuscript, a note ap­ pears to indicate this. 3. Oversize materials (maps, drawings, and charts) are photographed by sec­ tioning the original, beginning at the upper left hand comer and continu­ ing from left to right in equal sections with small overlaps. Each oversize page is also filmed as one exposure and is available, for an additional charge, as a standard 35mm slide or in black and white paper format.* 4. Most photographs reproduce acceptably on positive microfilm or micro­ fiche but lack clarity on xerographic copies made from the microfilm. For an additional charge, all photographs are available in black and white standard 35mm slide format.* *For more information about black and white slides or enlarged paper reproductions, please contact the Dissertations Customer Services Department T T A /T I Dissertation L J 1 V 1 1 Information Service University Microfilms International A Bell & Howell Information Company 300 N.
