Appendix 3. Residual gravity anomaly and computed depth to bedrock for drillholes penetrating into the Pantano? Formation
(conglomerate). Grid x and Grid y are in km., altitudes and depths are in meters; gravity anomalies are in mGal. CBGA is complete Bouguer gravity anomaly; error is misfit, in mGal, between model depth to bedrock gravity effect and residual gravity anomaly. A "flag" of "*" means calculated depth is less than total depth of well even though well did not penetrate into bedrock.|
