RI0004D. Correlation of Gravity Observations with the Geology of the Coal Creek Serpentine Mass, Blanco and Gillespie Counties, by F. Romberg and V. E. Barnes. 11 p., 4 figs., Reprinted from Geophysics, v. 14, no. 2, April 1949.
To purchase this publication in book format, please order RI0004.
Gravitational observations were made of the pre-Cambrian Coal Creek serpentine mass in Blanco and Gillespie Counties, Texas, the geology of which had been mapped previously. The observed gravitational anomalies indicate roughly the depth of the serpentine mass below which it may possibly grade into its parent peridotitic rock. Probable correlation between the gravitational map and the other geologic features of the area is indicated.
