CORRELATION OF GRAVITY OBSERVATIONS WITH THE GEOLOGY OF THE SMOOTHINGIRON GRANITE MASS, LLANO COUNTY, TEXAS

Abstract
Gravitational observations were made, and the geology mapped, on the Smoothingiron granite mass in Llano County, Texas. The observed gravitational anomaly was interpreted to give depth and a subsurface shape for the mass. Maps are provided showing the gravity contours and the geology, and geological and mathematical appendices are added.
