GEOL 121     Physical Geology (Lab)  (4)

A study of the geological features and processes that shape the earth's surface and subsurface. Lectures detail major components of the earth and the dynamic processes that generate them (including rocks, minerals, fossils, mountain belts, ocean basins, tectonic activity, magma formation, and climate change). Environmental issues related to geology (earthquakes, landslides, volcanic activity, groundwater contamination, and coastal and stream erosion) are major topics of discussion. Field-oriented lab exercises utilize excellent geological exposures of the Cumberland Plateau and the nearby Appalachian Mountains. Lecture, three hours; laboratory and field trips (including one weekend trip).

GEOL 221     Mineralogy (Lab)  (4)

A study of the chemistry, crystal structure, and properties of minerals. Lectures focus on the connection between the atomic structure and chemical bonding of minerals and the macro-scale physical properties that dictate their role in society. Laboratory work uses the physical properties of minerals observed in hand samples, combined with microscopy and X-ray diffraction to identify the most abundant minerals in the Earth’s crust. Prerequisite: GEOL 121 and one geology course at the 200 level or higher.

GEOL 222     Historical Geology (Lab)  (4)

Emphasis on North America and paleoenvironments of the Cumberland Plateau. Lecture, three hours; laboratory and field trips. Prerequisite: GEOL 121.

GEOL 225     Sedimentology (Lab)  (4)

A study of sedimentary rocks and the processes that form them. Field and class studies stress the link between modern sedimentary environments and their ancient counterparts. Emphasis on rocks of the Cumberland Plateau and other nearby areas. Lecture, three hours; laboratory and field trips. Prerequisite: GEOL 121.

GEOL 230     Paleoecology  (4)

A study of individuals, populations, and communities of plants and animals of the geologic past: their taphonomic histories, interactions with changing environments, and relationships to the sedimentary rock record. One weekend field trip. Prerequisite: GEOL 121.

GEOL 235     Earth Systems and Climate Change  (4)

A study of climate change, its causes, and the impact of such change on sea level, glacial regimes, and the development of life through geologic time. Special emphasis on evidence for past and recent climate change. Prerequisite: GEOL 121.

GEOL 236     Geology of Our Solar System  (4)

A study of the diverse geochemical and geophysical processes within our solar system, touching on terrestrial planets, gas giants, and minor bodies, including icy satellites. Lectures focus on the formation of the solar system, the interior structure of terrestrial planets, planetary atmospheres, volcanism, surface processes (fluvial, aeolian, impact), meteorites as clues to the solar system’s origin, and current NASA missions. One required weekend field trip. Prerequisite: GEOL 121.

GEOL 250     Special Topics  (2 or 4)

A seminar on a topic related to geology. This course may be repeated for credit when the topic differs. Prerequisite: GEOL 121.

GEOL 303     Soils (Lab)  (4)

A study of soils as they relate to land use, bedrock and geomorphology, site quality, and vegetation processes. Emphasizes field interpretation of soils as one component of terrestrial ecosystems. Lecture, three hours; laboratory and field trips, three hours. Prerequisite: FORS 121 or GEOL 121.

GEOL 305     Economic Geological Resources (Lab)  (4)

A study of economically valuable minerals and rocks (including metals, nonmetals, industrial minerals, and hydrocarbons) in terms of their origin, tectonic settings, extraction, and use. Topics include global distribution and genesis of deposits in relation to plate tectonic theory, prospecting techniques, mining methods, mining laws, economics of the mineral and petroleum industries, and environmental problems associated with exploration and development. Lecture, three hours; laboratory and field trips. Open only to juniors or seniors pursuing majors in geology or natural resources and the environment. Prerequisite: GEOL 121 and one geology course at the 200 level or higher.

GEOL 314     Hydrology (Lab)  (4)

Occurrence, movement, quality, and behavior of water in the hydrologic cycle with emphasis on groundwater, streams, lakes and karst systems. Includes techniques and problems of measurement and utilization. Lectures, three hours; laboratory and field trips, three hours. Prerequisite: GEOL 121.

GEOL 315     Watershed Contaminant Hydrology  (2)

A survey of the important natural and human-made contaminants and their movement through the groundwater and surface water systems of a watershed. Special emphasis is placed on metals and microplastics. Prerequisite: GEOL 314.

GEOL 318     Geomorphology  (4)

Geomorphology is the study of surficial landforms (erosional and depositional) and the processes that create them. This course investigates major controls on the development and evolution of erosional and depositional landforms, with attention to the ways earth surface processes respond to tectonic and climatic forcing. Significant emphasis is on weathering, fluvial, and slope-related (mass-wasting) processes, with additional consideration given to glacial, eolian, karst, eathering, and pedogenic (soil-related) processes. The coursework will involve collecting and interpreting field data from different geomorphic environments on the Cumberland Plateau and quantitative analysis of remote sensing data. Further course in introductory physics highly recommended. Prerequisite: GEOL 121.

GEOL 320     Igneous and Metamorphic Petrology (Lab)  (4)

Systematic study of the genesis, occurrence, composition, and classification of igneous and metamorphic rocks. Topics to include origin and crystallization of different magma types, metamorphic processes, and tectonic environments specific to certain rock suites. Laboratory work includes hand specimen and microscopic examination of igneous and metamorphic rock suites. Lecture, three hours; laboratory and field trips. Prerequisite: GEOL 221.

GEOL 322     Geology of the Western United States  (4)

The course focuses on the geological evolution of the Colorado Plateau, the Rio Grande Rift, and the Rocky Mountains. Extensive use of geologic maps and periodicals. An additional half course may be earned with successful completion of a field trip to the western United States. Open only to juniors or seniors pursuing majors in environment and sustainability, forestry, geology, or natural resources and the environment. Prerequisite: One laboratory course in geology numbered 200 or above.
