Sediment depth in the northern Colima Graben from 3-d interpretation of gravity

The N-S trending Colima Graben is one of three large graben systems which intersect 50 km SSW of Guadalajara, Mexico. Results from a gravity survey conducted within the northem part of the Colima Graben indicate that a 20 mgal Bouguer gravity anomaly is associated with graben infilling sediments, re...

Sumario:The N-S trending Colima Graben is one of three large graben systems which intersect 50 km SSW of Guadalajara, Mexico. Results from a gravity survey conducted within the northem part of the Colima Graben indicate that a 20 mgal Bouguer gravity anomaly is associated with graben infilling sediments, relative to gravity measured on plateaux on both sides of the graben. Toree-dimensional, two-body modeling of the gravity data indicate that the sediment depth is as much as 900 m. An estimate of 2 1/2 km of vertical offset within the northern Colima Graben is obtained from combining the predicted sediment depth with the topographic relief.
