Preface Earth science is an inherently local subject. No two places share exactly the same sequence of events that led to the way they are today. In this sense, Earth science is a subject to be explored in one’s own neighborhood, examining the detailed sequence of rocks for the history that has gone on under our feet. What is not possible from only one location is making sense of why this particular sequence of events took place when and where it did, particularly relative to sequences in other places around it. The distribution of rocks and landforms can be explained by processes that shape areas covering thousands of kilometers, such as the volcanism, mountain building, and sedimentary basins that accompany converging plates. These processes link widely separated sequences in a common history. Earth science educators at the Paleontological Research Institution, in working with teachers, have noted that no single source for educators exists that attempts to make sense of the disparate local features of the Midwestern United States in terms of a basic sequence of historical events and processes. Nationally distributed textbooks make few references specifi cally to the Midwest region. While a number of reasonably good resources exist for individual states, these do not take enough geographic scope into account to show how, say, the coals of Illinois are related to the Late Ordovician marine sedimentary rocks of southwestern Ohio, or why fossil fuels are found in some states and iron mining occurs in other nearby states. Further, these resources are not necessarily “teacher-friendly,” or written with an eye toward the kind of information and graphics that a secondary school teacher might need in their classroom. This Teacher-Friendly GuideTM is intended to fi ll this need for teachers. Explaining why (for example, certain kinds of rocks and their mineral resources are found where they are) is the most effective way of providing students with a tool to remember and predict the nature of local Earth science. The Midwest (though, like states, an artifi cial political area), is of the right scale to discuss the evolution of signifi cant portions of sedimentary basins, but also includes ancient igneous and metamorphic rocks. This means most Earth processes are illustrated by rocks present within a day’s drive, and that Earth phenomena can be illustrated with examples in areas students and teachers are likely to have been to or at least heard of. Since the rocks and landforms are relatively accessible, regional Earth science is an excellent subject for hands-on, inquiry- based teaching using, for example, real rocks and landforms. A transect across the Midwest in several places will reveal most major rock types that students should know and will come into contact with over the course of their lifetimes. The chapters chosen are by no means an exhaustive list, but refl ect especially the historical side of “solid Earth” geosciences. Each chapter starts with a brief review, then (in most chapters) describes the Earth science of three natural regions with the Midwest. There is a resource list at the end of each chapter. There is a chapter on fi eld work, not only on suggestions for how to do it, but how to integrate the fi eld into your curriculum through “virtual fi eldwork experiences.” There are chapters on Big Ideas in Earth system science—a few major conceptual ideas that run throughout the subject—and on using real- world regional Earth science in the context of the Next Generation Science Standards (NGSS). 3 This volume is part of a national series of seven Teacher-Friendly GuidesTM to regional Earth science, covering all 50 states. We also have two Teacher- Friendly GuidesTM to evolution, and other Guides in development. We would hope for our students that, years from now, they will be able to make sense of the place they live and the places they visit, through a comprehension of a few Big Ideas and a basic grasp of the “big picture” story of geological history of their area. It is our hope that this book might help teachers, and their students, grasp such a coherent understanding of their regional and local Earth system science. Robert M.

Fieldwork conducted in Pontotoc County,Mississippi, targeted two sites containing montmorillonitic sand in the Maastrichtian Ripley Formation. U-Pb detrital zircon (DZ) ages from these sands (n = 649) ranged from Mesoarchean (~2870 Ma) to Pennsylvanian (~305 Ma) and contained ~91% Appalachian-derived grains, including Appalachian–Ouachita, Gondwanan Terranes, and Grenville source terranes. Other minor source regions include the Mid-Continent Granite–Rhyolite Province, Yavapai–Mazatzal, Trans-Hudson/Penokean, and Superior. This indicates that sediment sourced from the Appalachian Foreland Basin (with very minor input from a northern or northwestern source) was being routed through the Mississippi Embayment (MSE) in the Maastrichtian. We recognize six lithofacies in the field areas interpreted as barrier island to shelf environments. Statistically significant differences between DZ populations and clay mineralogy from both sites indicate that two distinct fluvial systems emptied into a shared back-barrier setting, which experienced volcanic ash input.

  • Joe Curran Microfossils and the Depositional Environment of The
    Joe Curran Microfossils and the Depositional Environment of the Gunflint Iron Formation A thesis submitted in partial fulfillment of the requirements for the degree of Bachelor of Arts (Geology) at GUSTAVUS ADOLPHUS COLLEGE 2012 Abstract The Gunflint Iron Formation was deposited during the mid-Paleoproterozoic, shortly after the early Paleoproterozoic Great Oxygenation Event(GOE), when the atmosphere and oceans became oxygenated for the first time. The lowermost portions of the Gunflint Iron Formation contain black, early diagenetic chert with locally abundant microfossils. Reconstructing the life habits and ecology of the microfossil assemblages allows us to better understand the shallow water sedimantary conditions during the post GOE interval. Eosphaera and Kakabekia are two distinctive genera that occur in the Gunflint, but they likely had different habitats. Kakabekia has a morphology similar to iron metabolizing bacteria that live today in anoxic soil microhabitats. In the Gunflint, Kakabekia occurs in association with filamehts and coccoidal microfossils that likely lived in or near stromatolites on the sea floor. The association with this likely iron bacteria and a benthic microbial community suggests that most of the Gunflint microflora was benthic and possibly living in ferruginous, anoxic conditions. In contrast, Eosphaera fossils are rare and not strongly associated with the main community components. Eosphaera’s morphological similarity with the modern alga Volvox suggests that Eosphaera may also have hada photosynthetic metabolism. Eosphaera is plausibly interpreted as an oxygenic photosyhthesizer that lived in an oxic zone above the seafloor. If correct, this interpretation suggests close spatial proximity of oxic and anoxic environments in the Paleoproterozoic iron formations.

  • Driftless Area National Wildlife Refuge
    DRIFTLESS AREA NATIONAL WILDLIFE REFUGE McGregor, Iowa ANNUAL NARRATIVE REPORT FY2006 DRIFTLESS AREA NATIONAL WILDLIFE REFUGE McGregor, Iowa Fiscal Year 2006 _________________________ Prepared by Date _________________________ ______________________________ Refuge Manager Date Complex Manager Date ______________________________ Regional Chief, NWRS Date INTRODUCTION 1. Location The Driftless Area National Wildlife Refuge was established in 1989 for the protection and recovery of the threatened Northern monkshood and endangered Iowa Pleistocene snail. These species occur on a rare habitat type termed algific talus slopes. These are slopes with outflows of cold underground air that provide a glacial relict habitat to which certain species have adapted (see diagram below). The Driftless Area National Wildlife Refuge consists of ten units scattered throughout Allamakee, Clayton, Dubuque, and Jackson Counties in northeast Iowa. Total Refuge acreage is 811 acres with individual units ranging from 6 to 208 acres. Acquisition targets not only the algific slope, but surrounding buffer habitat that includes sinkholes important to air flow to the slope. Acquisition is ongoing, but limited due to insufficient funds. 2. Topography Refuge units are primarily forested and generally consist of steep topography with narrow creek valleys, large rock outcroppings, and karst features. Riparian and grassland habitat also occur on the Refuge. 3. Points of Interest The algific talus slope habitat of the Refuge harbors many unusual and rare plant and land snail species, some of which are also on the state threatened and endangered species list. These areas tend to be scenic with cliffs and rock outcroppings, springs, and coldwater streams. 4. Physical Facilities The Refuge office is located at the McGregor District of the Upper Mississippi River National Wildlife and Fish Refuge, McGregor, Iowa.

  • A Stable Isotopic Investigation of Resource Partitioning Among Neosauropod Dinosaurs of the Upper Jurassic Morrison Formation
    A stable isotopic investigation of resource partitioning among neosauropod dinosaurs of the Upper Jurassic Morrison Formation Benjamin T. Breeden, III SID: 110305422 [email protected] GEOL394H University of Maryland, College Park, Department of Geology 29 April 2011 Advisors: Dr. Thomas R. Holtz1, Jr., Dr. Alan Jay Kaufman1, and Dr. Matthew T. Carrano2 1: University of Maryland, College Park, Department of Geology 2: National Museum of Natural History, Department of Paleobiology ABSTRACT For more than a century, morphological studies have been used to attempt to understand the partitioning of resources in the Morrison Fauna, particularly between members of the two major clades of neosauropod (long-necked, megaherbivorous) dinosaurs: Diplodocidae and Macronaria. While it is generally accepted that most macronarians fed 3-5m above the ground, the feeding habits of diplodocids are somewhat more enigmatic; it is not clear whether diplodocids fed higher or lower than macronarians. While many studies exploring sauropod resource portioning have focused on differences in the morphologies of the two groups, few have utilized geochemical evidence. Stable isotope geochemistry has become an increasingly common and reliable means of investigating paleoecological questions, and due to the resistance of tooth enamel to diagenetic alteration, fossil teeth can provide invaluable paleoecological and behavioral data that would be otherwise unobtainable. Studies in the Ituri Rainforest in the Democratic Republic of the Congo, have shown that stable isotope ratios measured in the teeth of herbivores reflect the heights at which these animals fed in the forest due to isotopic variation in plants with height caused by differences in humidity at the forest floor and the top of the forest exposed to the atmosphere.

While sphenophytes and lycophytes generally are represented by only a few widespread and long-ranging taxa such as Archaeocalamites radiatus, Sphenophyllum tenerrimum and several species of Lepidodendropsis and Lepido- dendron, Visean floras in particular show a remarkably high diversity of fern-like foliage, including filiform types (Rhodea, Diplotmema), forms with bipartite fronds (Sphenopteridium, Diplopteridium, Spathulopteris, Archaeopteridium), others with monopodial, pinnate fronds (Anisopteris, Fryopsis) and still others characterized by several-times pinnate fronds (e.g., Adiantites, Triphyllopteris, Sphenopteris, Neu- ropteris). Most of these leaf types have been interpreted as belonging to early seed ferns, whereas true ferns seem to have been rare or lacking in impression/compression floras. In the upper Visean, two types of plant assemblages can be distinguished, i.e., the northern Kohlenkalk-type and the south-eastern Kulm-type assemblage.

(eds), Peri-Tethys: stratigraphie cor- relations 2, Geodiversitas 20 (4) : 643-662. ABSTRACT The Late Catbonifetous/Early Permian séquence in the Carnic Alps (Austria/ltaly) is a more than 2000 m thick succession of shallow matine clastic and carbonate sedimentaty rocks. The succession unconformably overlies rhe folded Variscan basement and is divided into Bombaso Fotmation, Auernig Group, Rartendotf Group and Trogkofel Group. Auernig Group and Rattendorf Group are charactetized by clastic-catbonate cycles related to Gondwana glacioeustatic sea level changes. Catbonates contain abundant fossils throughout the séquence, biostratigtaphy is mainly based on fusulinids. Fine-grained clastic intervais contain abundant plant fossils, allowing a close corrélation with fluvial succession of the Eastern Alps KEYWORDS (Stangnock Fotmation of the Gutktal Nappe). Fusulinids of the Carnic Alps Peri-Tethys, Late Carboniferous, show high similarity wirh those of the Russian Platfotm, Donets Basin and Early Permian, Ptedonets Trough, Southern Urals and particulatly with Central Asia. Carnic Alps, faciès, Uppermost Moscovian, Kasimovian, Gzhelian, lowermost Asselian, late biostratigraphy, Asselian, Sakmarian and Artinskian équivalents ate established and précise fusulinids, corrélation with sttatotype légions have been completed.
