She attended Douglas MacArthur High School in San Antonio, Texas. Miss Cason entered Baylor University in September, 1975 and received a Bachelor of Science degree in Geology in August 1979. Her bachelor's thesis was entitled “Microfauna of the Pepper Shale Formation, East-Central Texas.” During the summer of 1978, Miss Cason worked in Tokyo, Japan teaching English and participating in cultural exchange with Japanese students. She began work on her Master of Science degree in September, 1979 and will be completing this work in November, 1981. During her stay at Texas A&M, Miss Cason has participated in various research projects directed by Dr. Christopher C. Mathewson. These studies involved the Geology, Engineering Geology, and Mining Geology of Texas lignites and lignite mining primarily. The title of her thesis is “Engineering Geologic Feasibility of Lignite Mining in Alluvial Valleys by Hydraulic Dredging Methods.” Search for other works by this author on: GSW Google Scholar Environmental & Engineering Geoscience (1982) xix (1): 1–4. https://doi.org/10.2113/gseegeosci.xix.1.1 Article history first online: 13 Jul 2017 Cite View This Citation Add to Citation Manager Share Icon Share Twitter LinkedIn Tools Icon Tools Get Permissions Search Site Citation CYNTHIA LYNN CASON; 1981 Student Professional Paper: Engineering Geologic Feasibility of Lignite Mining in Alluvial Valleys by Hydraulic Dredging Methods.

The shallow groundwater table, flooding, acid water production, and prime agricultural usage will make the floodplain very difficult to mine by conventional surface mining methods. Application of well developed hydraulic dredging techniques to lignite recovery in alluvial valleys may represent an increase in mining economy and a decrease in adverse environmental effects. It is envisioned that a small, portable dredge will utilize the existing hydrologic conditions to mine the floodplain as a supplement to major surface mining operations, and provide an additional 4.7 billion tons of lignite for use.
