USGS CMG UGEOLEG_1 Metadata

Scientific objectives of Investigation of this leg were:
1) to define the details of folding and faulting on the west side of the Bay of 
Campeche;
2) to study the extension into the bay of the Mexican volcanic belt and related 
volcanic lineaments;
3) to investigate the origin of a belt of salt domes that extends along the 
floor of the east side of the basin; and
4) to acquire new evidence that might bear on the origin of the Gulf of Mexico.
