Marty Horn joined the Louisiana Geological Survey as an Assistant Professor - Research in January 2007. He was previously at the LSU Department of Geology & Geophysics as Instructor and Field Camp Director. Dr. Horn earned a B.S. in Geophysics at the University of Oklahoma in 1982, an M.S. in Geology at the Arizona State University in 1986, and a Ph.D. in Mathematical Sciences & Geology at the University of Texas at Arlington in 1996. He has taught courses in Physical Geology, Historical Geology, Mineralogy, Igneous and Metamorphic Petrology, Volcanology, and Field Geology (sedimentary, igneous, metamorphic, and structural geology). His early research topics at LGS included stratigraphy and structural geology of the North Louisiana Salt Basin structural province in northwestern Louisiana, mapping and petrographic contributions to the USGS STATEMAP initiative to produce 100k scale geologic maps of Louisiana, sampling and analysis of ground water chemistry related to the Haynesville Play, northwest Louisiana, and measurement and analysis of stream discharge at over 50 gaging stations across the State. His current research develops and applies geophysical techniques of magnetometry and electrical resistivity to study near-subsurface geological relationships and to resolve buried anthropogenic features such as buried waste, pipelines, historic and pre-historic archaeological features, and cemetery and criminal graves. Marty has recently reinforced LGS’ mission in geologic mapping of the state of Louisiana at 1:24,000 scale under the USGS STATEMAP program.
