The understanding of all these elements and migration mechanisms of gases in the petroleum system play a key role to make an appropriate interpretation of surface geochemistry data.
Axial surfaces represent the boundary between two adjacent dip panels within a given fold.
Axial surface maps define fold trends, constrain underlying fault geometry and slip, and highlight and connect regions that can be interpreted by a series of balanced cross sections. In this work, we propose the integration of axial surface and geochemistry surface anomaly maps to identify leads in fold belts. Vertical projection is used because it preserves the horizontal position of the structure. As an example of the application and integration of both techniques, we present the results of a study in a region of approximately 300 km2 located in western Venezuela. Most structural trends in the area have a NE-SW orientation.
