Correlation of Gravity of the Coal Creek Serpentine Mass, Blanco and Gillespie Counties, Texas

Description: Abstract: "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" (p. 151).

Naturally Occurring Groundwater Contamination in Texas

Description: Report on a study to evaluate statewide water quality: "Groundwater quality in the state is greatly impacted by naturally occurring contamination derived from meteoric sources (precipitation), soils, and/or geologic sources [... which] contrast with anthropogenic substances that are added to the system through human activities. The objective of this study is to assess all naturally occurring and limiting chemical constituents that affect the quantity of fresh groundwater in Texas" (p. 1).
