The author believes there is a place for the geologist in the sand and gravel industry and points out some of the marginal information that a geologist should have in order to meet the needs of the world's largest (tonnage-wise) mining industry. Benificiation of sand and gravel other than conventional washing and screening is rapidly becoming more important owing to depletion and to more exact specification requirements. The reader can get a quick glimpse of a great industry that has grown during the past few decades from a way-side pit to its present status. The problems of the ready-mixed concrete, the asphaltic concrete, and the sand and gravel operator are so closely related that the three industries can often be classed as one. Sources of more detailed information are included.
