The estimated value of nonfuel mineral production in Indiana in 2001 was about $718 million, up more than 3% from 2000. Increased values of crushed stone and portland and masonry cement were responsible for most of the increase, aided by a record $737 million in highway construction projects completed by the state's department of transportation.
Nationally, Indiana ranked 20th in value of nonfuel mineral production. In 2001, Indiana ranked 1st in dimension stone, 4th in peat, in the top five in masonry cement, 8th in gypsum, and was a significant producer of portland cement, crushed stone, construction sand and gravel, and common clays.
