PROCEEDINGS OF THE
SIXTH INTERNATIONAL SYMPOSIUM ON

BOREHOLE GEOPHYSICS

FOR MINERALS, GEOTECHNICAL
AND GROUNDWATER
APPLICATIONS

Sponsored by:

The Minerals and Geotechnical Logging Society

and

Los Alamos National Laboratory

We wish to acknowledge the support of Los Alamos National Laboratory's EES-Division, C. Wes Myers, Division Leader; EES-1, Geology and Geochemistry group, Group Leader M. James Aldrich; and P-4, Conference and Visits Management's LeeRoy Herrera and Marion Hutton. Without the financial support and encouragement of Myers and Aldrich and the expertise and diligent effort of Herrera and Hutton this symposium would not have been possible.
