Reply to comments by J. García Abdeslem on: "Gravity field of the southern Colima graben"

Abstract

We. thank Juan Garcfa-Abdeslem (1995) for his interest in our gravity study in the area of the southern Colima graben (Bandy et al., 1993). The structure and tectonics of this region are currently subject to much debate. We welcome this opportunity to clarify our original work and to extend our analysis to include 2.5-D models. Based on the comments by J. Garcia-Abdeslem (JGA) we select three main topics which may require further explanation or investigation. These are: (1) whether our profile is correctly oriented; (2) why a 2-D modeling procedure was used for a case where the structure is clearly not 2-D and, more importantly, whether this simplified approach produces results significantly different than the theoretically' more appealing 2.5-D method; and (3) what the non-uniqueness inherent in the gravity method implies in terms of the validity of our conclusions. We take this opportunity to point out a correction to our 1993 paper. All the figure captions are correct, but the maps illustrated in figures 2 and 4 should be switche.
