The distribution, causes, effects and prediction of earthquakes and volcanoes.  This course does not count towards advanced hours for Geology majors.

GEOL 3304 Forensic Geology (3-0) The course is divided into two parts; "criminal" forensics and "civil" forensics. The first part examines such things as soil, rock, glass, etc., used in the commission of crimes. The second part looks at case studies of landslides, floods, etc., where people have sued for damages.

GEOL 3401 Interdisciplinary Geographical Information Systems (3-2) This course is designed to introduce the concepts of computer-based spatial data handling, referred to as geographical information systems (GIS). The interdisciplinary approach focuses on bringing students from diverse academic backgrounds together in a team effort to learn the fundamentals of GIS, including data sources, input, manipulation and output presentation. There are no prerequisites, but it is recommended that the student have completed an introductory class in one of the following: geology, geography, biology, natural resource managment or archeology.  Prerequisite: CS1301, OFS1384, equivalent or approval of instructor.

GEOL 3402 Structural Geology (3-3) A study of the structural features (faults, folds, etc.), their classification, identification, occurrence, causes and geographic distribution. Prerequisite: Geology 1401, Math 1316

GEOL 3403 Advanced Geographical Information Systems (3-3) This course is designed to build on the skills learned in the Interdisciplinary GIS class.  Topics will include a review of advanced vector analysis, followed by a detailed coverage of raster based analysis.  Projects will include the creation and manipulation of digital elevation models, classification on aerial and satellite imagery, and vector to raster conversion and analysis.  The projects and assignments will utilize an extensive Trans-Pecos spatial database housed in the Sul Ross GIS lab. Software used will include the Spatial and 3D Analyst extension for ArcGIS and ERDAS Image.  Prerequisite: Geology 3401 or approval of instructor.

GEOL 3408 Stratigraphy and Sedimentation (3-3) A study of the processes governing the formation and distribution of recent sediments, which established the guiding principles used in the classification, correlation and interpretation of ancient, stratified sedimentary rocks. The stratigraphic record is largely the result of the continuity of sedimentary processes through the dimension of geologic time. Prerequisite: Geology 1402

GEOL 3410 Geochemistry (3-1) A survey of the application of chemical principles to the problems of geology. Topics include the origin and distribution of the elements in igneous, metamorphic and sedimentary rocks. Basic concepts of thermodynamics, solution chemistry and isotope geochemistry will be discussed. Prerequisite: Chemistry 1402

GEOL 3411 Invertebrate Paleontology (3-3) The course deals with the morphology, classification, identification, evolutionary trends and geological distribution of invertebrate fossils. Laboratory work consists of systematic study of index fossils as well as representative fossils of various phyla. Prerequisite: Geology 1402 or permission of the instructor

GEOL 3412 Geomorphology (3-3) An introduction to surficial processes and land forms. Understanding the landscape upon which we live and depend can be of vital importance to nearly everyone from the homeowner to the civil engineer. Fluvial, glacial, coastal, groundwater and weathering processes will be studied along with lithologic and structural influences. Labs will include map and photo interpretation and field studies. Prerequisite: Geology 1401

GEOL 3601 Field Geology (3-6) A six weeks summer field course on the methods or techniques of geologic surveying, the nature and construction of topographic and geologic maps, measurement of stratigraphic sections and preparation of geological reports.
