Prerequisite: 112 or permission of instructor. F. (Group II)
290. Mineralogy (1.25 units, Martin) (Alternate years.)
Contemporary society relies upon minerals for many of the products that it uses. Mineralogy involves the systematic study of minerals with an emphasis on the common rock-forming minerals. The basic principles of chemistry and symmetry are used to understand mineral properties and crystal structures. Topics include crystallography, crystal chemistry, the origin of mineral color, environmental issues related to minerals, and systematic study of major silicate and non-silicate minerals. Lecture and laboratory. Field trip in GEOL 290 or 310. Prerequisites: 110 and CHEM 110, or CHEM 110 concurrent with permission of the instructor. F. (Group II)
310. Igneous and Metamorphic Petrology (1.25 units, Martin) (Alternate years.)
Knowledge about rocks, their origin, and their distribution contributes to the solution of many geological problems. Petrology focuses on the systematic study of igneous and metamorphic rocks including techniques of hand-specimen identification and classification. Basic principles of phase equilibria and geochemistry are used to understand the origin and behavior of magmas, the crystallization of magma, the origin of rock textures, and metamorphism. The dynamic nature of metamorphism in response to changes in the geological environment, as well as the relationships among tectonic processes, magma generation and metamorphism are examined. Lecture and laboratory. Field trip in GEOL 290 or 310. Prerequisite: 290. S. (Group II)
315. Petrography (1.25 units, Fryer) (Alternate years.)
Principles and practice of identification and interpretation of minerals and rocks using the polarizing light microscope and the scanning electron microscope.

320. Paleontology (1.25 units, Mann) (Alternate years.)
Paleontology studies life’s history and elucidates our understanding of the role of life through time. It offers a unique historical perspective of humankind in nature, provides tools for the discovery and development of resources on which industry and agriculture depend, presents a framework for understanding the sensitivity of the global system to past perturbations, and helps us identify possible consequences of recent ecosystem change. Although Paleontology (320) covers the systematics and taxonomy of the major fossil producing invertebrate phyla, the course focuses on the paleobiology of fossils. Such topics as preservation (taphonomy), growth (ontogeny, heterochrony, and functional morphology), evolution (phylogeny, evolutionary theory, evolutionary patterns, and extinction), and fossil distribution (paleoecology and paleobiogeography) are the primary concepts addressed. The class also contains seminars in which students read and discuss the primary literature. The laboratory portion of the course is dedicated to examining fossils and addressing paleontologic questions. The laboratory includes several field trips so students have the opportunity to collect and work on the excellent fossilized material preserved in the sediments of central and southern Ohio. Prerequisite: 112 or advanced standing in botany or zoology. F. (Group II)
330. Sedimentology and Stratigraphy (1.25 units, Mann) (Alternate years.)
Sedimentology and stratigraphy are branches of geology that deal with the identification, description, interpretation, and the distribution (both temporal and spatial relationships) of strata. The course begins by considering classic sedimentology (the formation of sedimentary rocks) and then progresses to consider sedimentation in the context of depositional environments. This is followed by examining sedimentation at a larger scale: sedimentation in basins (tectonics, eustasy, and isostasy). The course also covers classic stratigraphy as well as the many other developments (sequence stratigraphy, quantitative biostratigraphy, magnetostratigraphy, and chemostratigraphy) in the field. The field-oriented laboratory spends at least half of the sessions in the field addressing geologic problems. In addition to working on the local geology, the class visits Central Pennsylvania during a four-day trip to examine the Paleozioic history of the Appalachian Basin. Prerequisite: 112 or permission of instructor. F. (Group II)
