ACKNOWLEDGMENTS

Fieldwork for this project was done in 1988 through 1990. We appreciate the support of National Science Foundation (INT-8608620) and CONICIT (Venezuela) and the supplemental funding by the Melon Foundation. We benefited from discussions with many Venezuelan researchers, particularly Felipe Audemard, and we thank Brooks Ellwood and Bill MacDonald for thoughtful reviews.

ABSTRACT

Paleomagnetic analyses of 161 samples of Jurassic through Eocene age from 11 sites in the Venezuelan foothills of the Perijaacute Mountains yield a pole position at 44.1deg N, 6.6deg E with an error of A95 = 9.6deg. These data indicate that the sampling sites underwent a 50degplusmn 12deg clockwise rotation. The rotations are interpreted to be the result of Neogene compression, which caused the rotation of fault-bounded blocks. Model calculations suggest a shortening between 8 km and 20 km across the eastern portion of the Perijaacute Mountains.
