Gravity and magnetic data are used to determine the possible location of detachment fault-related upper-plate tilt blocks that may contain ore bodies in Jurassic gneisses similar to or associated with the Mesquite gold mine of southeastern California. Residual gravity and magnetic anomaly maps show the possible location of several of these tilt blocks buried beneath Tertiary and Quaternary sedimentary rocks north of the Chocolate Mountains. Gravity models constructed along profiles northeast of the Mesquite Mine, with detailed gravity data and constrained by surface density measurements and nearby seismic reflection profiles, indicate that the proposed tilt blocks containing the possible ore bodies in Jurassic gneiss lie between 0.05 and 0.20 km beneath the earth's surface.
