A Hydrogeologic and Mapping Investigation of the St. Lawrence Formation in the Twin Cities Metropolitan Area Executive Summary T
Minnesota Geological Survey (MGS) Open File Report 06-04 (Open File Reports are not subjected to conventional MGS editorial standards) A HYDROGEOLOGIC AND MAPPING INVESTIGATION OF THE ST. LAWRENCE FORMATION IN THE TWIN CITIES METROPOLITAN AREA Runkel, A.C., Mossler, J.H., Tipping, R.G., and Bauer, E.J. Minnesota Geological Survey 2642 University Ave W., St. Paul, Minnesota 55114-1057 EXECUTIVE SUMMARY This report summarizes the results of a two year project conducted by the Minnesota Geological Survey to map the Upper Cambrian St. Lawrence Formation and investigate its hydrologic properties in the Twin Cities Metropolitan area (TCMA). Funding was provided by the Minnesota Department of Health. Final products are a map delivered in electronic format that can be used with Arcview 3.2 GIS software, and this informal report. Our hydrogeologic study indicates that the St. Lawrence Formation commonly has a moderate to high horizontal hydraulic conductivity across all of the study area. In conditions of shallow burial beneath younger bedrock it is most similar in the development of secondary pores and measured hydraulic properties to fractured carbonate rock aquifers. Discrete intervals with secondary pores have a high horizontal hydraulic conductivity whereas rock between these intervals are orders of magnitude lower in conductivity. The properties of the St. Lawrence Formation in a vertical direction are not as well- understood, but available data are consistent with the traditional classification of the formation as an aquitard. However, the integrity of the formation as an aquitard in a vertical direction, particularly under conditions of shallow burial such as where it is uppermost bedrock, has not been rigorously tested, and may be markedly variable across the TCMA. -

Recent Fossil Finds in the Indian Islands Group, Central Newfoundland
Current Research (2006) Newfoundland and Labrador Department of Natural Resources Geological Survey, Report 06-1, pages 221-231 RECENT FOSSIL FINDS IN THE INDIAN ISLANDS GROUP, CENTRAL NEWFOUNDLAND 1W.D. Boyce, P.Geo. and 2W.L. Dickson, P.Geo. 1Regional Geology Section 2Mineral Deposits Section ABSTRACT During the 2004 and 2005 field seasons a number of fossiliferous exposures of the Indian Islands Group rocks were exam- ined. The results of these fossil surveys are presented here. The occurrence of the bryozoan Stictopora scalpellum (Lonsdale, 1839) in many outcrops of the Silurian Indian Islands Group definitively dates these exposures as latest Wenlock (late Home- rian). Several richly fossiliferous localities yield faunas indicative of Wenlock, late Wenlock (Homerian), and middle Ludlow (late Gorstian to early Ludfordian) ages. INTRODUCTION Dudley, West Midlands, England, of late Homerian (latest Wenlock) age (Snell, 2004, page 6, Text-Figure 4).

A. Munter G. A. Ludvigson B. J. Bunker Iowa Geological Survey Iowa Geological Survey Donald L. Koch Director and State Geologist 123 North Capitol Street Iowa City, Iowa 52242 Foreword An assessment of the quantity and quality of water available from the Dakota (Sandstone) Formation 1n northwest Iowa is presented in this report. The as sessment was undertaken to provide quantitative information on the hydrology of the Dakota aquifer system to the Iowa Natural Resources Council for alloca tion of water for irrigation, largely as a consequence of the 1976-77 drought. Most area wells for domestic, livestock, and irrigation purposes only partial ly penetrated the Dakota Formation. Consequently, the long-term effects of significant increases in water withdrawals could not be assessed on the basis of existing wells. Acquisition of new data was based upon a drilling program designed to penetrate the entire sequence of Dakota sediments at key loca tions, after a thorough inventory and analysis of existing data. Definition of the distribution, thickness, and lateral and vertical changes in composition of the Dakota Formation has permitted the recognition of two mem bers. Additionally, Identification of the rock units that underlie the Dakota Formation has contributed greatly to our knowledge of the regional geology of northwest Iowa and the upper midwest. -

Geology and Why it Matters This story was made with Esri's Story Map Journal. Read the interactive version on the web at http://arcg.is/qrG8W. The geology, landforms and land features are extremely important components of watersheds. They influence water quality, hydrology and watershed resiliency. Every watershed has critical areas where water interacts with and mobilizes contaminants, including non-point and point source contributions to surface water bodies. Where and how nutrients, bacteria and/or pesticides are mobilized to reach surface water can be better understood through a careful study of subsurface hydrology, or hydrogeology, which, according to the Iowa Geological and Water Survey Bureau, “allows better identification for sources, pathways and delivery points for groundwater and contaminants transported through the watershed’s subsurface geological plumbing system.” Diagram courtesy of Iowa DNR Iowa Geological Survey The highly developed karst topography and highly permeable bedrock layers of the Upper Iowa River increase the depth from which actively circulating groundwater contributes to stream flows, making an understanding of the hydrogeology even more important. Fortunately, the Iowa Geological and Water Survey Bureau completed a detailed mapping project of bedrock geologic units, key subsurface horizons, and surficial karst features in the Iowa portion of the Upper Iowa River watershed in 2011. The project “provides information on the subsurface part of the watersheds, which is necessary for evaluating the vulnerability of groundwater to nonpoint-source contamination, the groundwater contributions to surface water contamination, and for targeting best management practices for water quality improvements.” The map on the right shows the surface elevation of bedrock in the state of Iowa and the Upper Iowa River Watershed. -

Deep Oil Possibilities of the Illinois Basin
s Ccc 36? STATE OF ILLINOIS DEPARTMENT OF REGISTRATION AND EDUCATION DEEP OIL POSSIBILITIES OF THE ILLINOIS BASIN Alfred H. Bell Elwood Atherton T. C. Buschbach David H. Swann ILLINOIS STATE GEOLOGICAL SURVEY John C. Frye, Chief URBANA CIRCULAR 368 1964 . DEEP OIL POSSIBILITIES OF THE ILLINOIS BASIN Alfred H. Bell, Elwood Atherton, T. C. Buschbach, and David H. Swann ABSTRACT The Middle Ordovician and younger rocks of the Illinois Basin, which have yielded 3 billion barrels of oil, are underlain by a larger volume of virtually untested Lower Ordovician and Cambrian rocks. Within the region that has supplied 99 percent of the oil, where the top of the Middle Ordovician (Trenton) is more than 1,000 feet be- low sea level, less than 8 inches of hole have been drilled per cubic mile of the older rocks. Even this drilling has been near the edges; and in the central area, which has yielded five- sixths of the oil, only one inch of test hole has been drilled per cubic mile of Lower Ordovician and Cambrian. Yet drilling depths are not excessive, ranging from 6,000 to 14,000 feet to the Precambrian. More production may be found in the Middle Ordovician Galena Limestone (Trenton), thus extending the present productive regions. In addition, new production may be found in narrow, dolomitized fracture zones in the tight limestone facies on the north flank of the basin . The underlying Platteville Limestone is finer grained and offers fewer possibilities. The Joachim Dolomite oil- shows occur in tight sandstone bodies that should have commercial porosity in some re- gions. -

All other material © 2015 Michael E. Dittes All Rights Reserved. ACKNOWLEDGMENTS I would like to extend my thanks to those, who without their help I would not have been able to bring this project to completion. First and foremost, I thank Professor Joseph Labuz who took a chance on me, by offering me a TA-ship. Through my time in school, Joe helped me stay focused when I started to move off on tangents, offered timely advice, and over the years has become much more than my advisor. I am proud to think of him as a friend. Professors Andrew Drescher and Peter Huddleston also deserve special thanks for providing critical review of my work, and agreeing to sit on my thesis committee. To Ms. Tiffany Ralston who had an uncanny way of knowing what I needed to do, and how, before I knew myself. To Charles Nelson who helped me streamline my thesis project and helped me gain access to the Minnesota Library Archives construction site. To my fellow graduate students with whom I debated, joked and laughed, you helped me see things that I was missing. Your input was invaluable and you have my deep appreciation. -
