208 MINERALS YEARBOOK, 1978-79 
 Industrial sand was produced by MartinMarietta Aggregates in Clayton County
and by Booneville Gravel Co. in Dallas County during 1978. Output was principally
for foundry use. 
 Approximately 90% of all sand and gravel shipments were made by truck. 
 Stone.—Crushed and dimension limestone were the only types of
stone
produced in Iowa during the biennium 1978-79. Production was derived from
more than 300 quarries located in approximately twothirds of the State's
counties. Scott County was the leading county in crushed stone output during
1978, followed by Cerro Gordo, Madison, Linn, and Black Hawk Counties, respectively.
These five counties, which produced more than 1 million tons each and 
collectively accounted for about one-third of the total State production,
are geographically located to best supply the cement manufacturing and construction
needs of the urban areas of Davenport, Mason City, Des Moines, Cedar Rapids,
and Waterloo. 
 More than half of the State's crushed stone output was from the operations
of 10 firms, each producing quantities in excess of 1 million tons in 1978.
Production from the individual quarry operations ranged from less than 25,000
tons to more than 1 million tons. In 1978, 41% of the quarries produced less
than 25,000 tons; 33% between 25,000 tons and 100,000 tons; 24% between 100,000
tons and 500,000 tons; and the remainder produced more than 500,000 tons.
