Abstract

This thesis presents the first use of the wide angle seismic reflection technique to determine crustal thickness in north-central Alabama. Records of quarry blasts recorded on an array of seismometers were used to determine travel times of reflected P waves from the Mohorovicic discontinuity (the boundary between the crust and the mantle) in the distance range 100 to 150 km. 2 2 The velocity calculated from the slope of a T versus X plot was 6.226 +_ 0.362 km/sec is considered to be more reliable than the depth of 34.9875 _+ 8.8810 km calculated from the intercept. These results are consistent with recent refraction results from this area and indicate a crust of intermediate composition.
