An Abstract of the Thesis Of
AN ABSTRACT OF THE THESIS OF Steve Rene' Moothart for the degree of Master of Science in Geology presented on December 7. 1992. Title: Geology of the Middle and Upper Eocene Mcintosh Formation and Adjacent Volcanic and Sedimentary Rock Units. Willapa Hills. Pacific County. Southwest Washington. Signature redacted for privacy. Abstract approved: Alan R. Niem. The early to middle Eocene submarine basalts of the Crescent Formation form the core and basement of the structurally uplifted Willapa Hills region of southwest Washington. The formation consists of a thick sequence of predominantly subalkaline, tholeiitic pillow basalts and breccias formed as oceanic crust and seamounts at a sea floor spreading ridge or pull apart basin along the rifting continental margin of North America. Radiometric (Ar40 - Ar39) dating of the pillow basalt indicates an age of approximately 53 -55Ma for the formation. Foraminifera collected from mudstones interbedded with the pillow basalts of the Crescent Formation in southwestern Pacific County indicate a Ulatisian to lower Narizian (middle Eocene) age for the basalts and suggest that they were erupted in lower-middle bathyal(1500 -2000 m) water depths. Locally associated with the pillow basalts are hyaloclastic basalt breccias and basaltic sandstones. Overlying, and interbedded with the basalts of the Crescent Formation is the middle and upper Eocene Mcintosh Formation, which is composed of three members (informal). Stratigraphically from the lowest, these members are: 1) Fork Creek member; 2) Lebarn member, 3) McIntosh Volcanics member. The Fork Creek member consists of a thick sequence of normally graded, micaceous, coarse- to fine-grained, arkosic and lithic arkosic sandstones deposited by sand-rich, high concentration turbidity currents in the deep marine-marginal basin. -

State of Washington ARTHUR B. LANGLIE, Governor Department of Conservation and Development W. A. GALBRAITH. Director DIVISION OF MINES AND GEOLOGY SHELDON L. GLOVER, Supervisor Bulletin No. 43 EOCENE STRATIGRAPHY OF THE LOWER COWLITZ RIVER EASTERN WILLAPA HILLS AREA, SOUTHWESTERN WASHINGTON By DONALD ANTON HENRIKSEN STAT£ ,..RINTl~G PLANT. OLYMPIA, WASH,. 19,15 ~ For sale by Department or Conservation and Oevelopment, Olympia, Wasrungton. Price, $1.50. FOREWORD This bulletin deals with a part of southwestern Washington for which only general information has been previously available. The details of structure and stratigraphy throughout much of the area have been unknown, and the igneous rocks of the area have hereto fore received only perfunctory attention. The data here provided will be of interest to anyone concerned with the geology of this part of the state, not only for specific use in the area under discussion but also in studies of adjacent areas where similar rocks occur. The field work upon which the report is based was done by the author during the summer seasons of 1951, 1952, and 1953. The report, when completed, was a dissertation submitted to the School of Mineral Sciences and the Committee on Graduate Study of Stanford University, in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Geology. The Division of Mines and Geology is grateful to the author, Dr. Donald A. Henriksen, for his permission to publish the report as Bulletin No. 43 of its series of geologic studies of Washington, thus making the material more generally available than it might other wise be. -
