A Gravity Investigation Of The Tobacco Root Batholith Southwest Montana, Stephen Charles Tatum
Masters Theses
The objective of this research was to delineate and profile the Late Cretaceous Tobacco Root batholith in southwestern Montana through the application of the gravitational method. This survey was accomplished by obtaining 232 gravity measurements in four profiles across the batholith. After correcting for known variations in the gravity field, a Bouguer anomaly map of the batholith and surrounding host rocks was created. Four residual gravity profiles and map, created by subtracting the regional gravity from the Bouguer anomaly, reveal a maximum negative gravity anomaly in the center portion of the batholith which is parallel to the trend of the …
