Fine large geological map of the state of Texas, published in 1933 by the University of Texas.
The map was created in the early 1930s by several of Texas's leading petroleum and geological scholars, as noted below.
The map notes:
The base and geologic mapping for this map are adapted from Geological Map of Texas, preliminary edition, issued by the United States Geological Survey, 1932; compiled between the years 1924 and 1932 by the United States Geological Survey, in cooperation with the Bureau of Economic Geology of the University of Texas, the geologists of Texas, and the oil companies of Texas, all available published material and from unpublished data furnished by geologists of the United States Geological Survey, the Bureau of Economic Geology, and by consulting geologists.
Elias Sellards
In 1918, moved to Austin, where he worked in the Bureau of Economic Geology at The University of Texas at Austin. From 1938–1945, Dr. Sellards held a dual directorship; he was director of both the Texas Memorial Museum and the Bureau of Economic Geology. His research focused on vertebrate fossils and evidence of early humans.
Walter Scott Adkins
Walter Scott Adkins taught as professor of geology at Texas Christian University from 1913 to 1915, instructor in anatomy at the Illinois Medical School from 1916 to 1918, and assistant professor of anatomy at Baylor Medical School in Dallas during the 1918–19 term. He was with the Texas Bureau of Economic Geology from 1919 to 1921. From 1921 to 1925 he worked for the Mexican petroleum company El Águila. At the Sorbonne in the 1925–26 term he studied under Emil Haug and Leon Perviquiere. In 1926 he returned to the Bureau of Economic Geology before joining Shell Development Company in 1934. In 1931, he became the first paleontologist to hold a John Guggenheim Memorial Fellowship. During this period, he studied with L. F. Spath at the British Museum. He served Shell Development as chief stratigrapher and head of the special-problems research group until his retirement in 1950, after which he served as a consultant until his death.
Adkins was vice president of the Society of Economic Paleontologists and Mineralogists in 1931 and served as the first chairman of the society's research committee in 1929 and 1930. He is perhaps best remembered for his Handbook of Texas Cretaceous Fossils (1928) and his Mesozoic Systems in Texas (1933). With Will McClain Winton he coauthored Paleontological Correlation of the Fredericksburg and Washita Formations in North Texas (1920), the first detailed biostratigraphical study to come out of Texas. His Stratigraphy of the Woodbine and Eagle Ford, Waco Area, Texas (1951), written in collaboration with Frank E. Lozo, is another outstanding work about solving geologic problems through biostratigraphy. Among Adkins's reports to the Shell company, his works on the distribution of shoestring and barrier sands in the subsurface of the Miocene (1935) and the "Time of Origin and Migration of Oil" (abstracted at the International Geological Congress, Mexico, 1956) were particularly important.
Frederick Byron Plummer
Frederick Byron Plummer (1885-1947) was a Geologist in the University of Texas Bureau of Economic Geology and Professor of Petroleum Engineering at the institution from 1928 until his death at the age of 61. Plummer received his education at Dartmouth College and the University of Chicago. He worked as a consultant for the Dutch Shell Group and lectured at Vassar College before coming to teach at Texas. Plummer was best known for his research on the recovery of salt water in oil wells.
Plummer's wife, Helen Jeanne Plummer, was a special lecturer in 1932-33 in micropaleontology at Northwestern University. She did research in a laboratory in her home and later had facilities in Austin at the University of Texas Bureau of Economic Geology, where she became a consulting geologist in 1933. After the death of her husband in 1947, she became a regular staff member of that organization. During the late 1940s she helped Petróleos Mexicanos establish a micropaleontological laboratory.
Following up on the work of Dorothy Ogden Carsey, Helen Plummer became proficient in the study of foraminifera of the Cretaceous and the Paleocene; she described many new species and several new genera. In order to obtain and study samples she served without charge as a consultant for wildcatters and petroleum explorers. She acquired an international reputation through her research and publications and by 1931 was regarded in England as one of the leading American micropaleontologists. She died in Austin on January 11, 1951.
