Remote Sensing and Airborne Geophysics in the
Assessment of Natural Aggregate Resources
By D.H. Knepper, W.H. Langer, and S.H. Miller
U.S. Geological Survey Open-File Report 94-0158
This publication describes the methodology for assessment of natural
aggregate resources using remote sensing and airborne geophysics.
Natural aggregate derived from crushed stone and deposits of sand and gravel
is a vital commodity of the construction industry, and its potential source
distribution is needed for land-use decisions. This report describes the
types of natural aggregate deposits and their distribution in the United States.
It focuses on the aspects of the deposits that are most amenable to remote
sensing and airborne geophysical exploration techniques and identifies the
physical rock properties and characteristics of the deposit essential to
