  395The Mineral Industry of 
North Carolina 
This chapter has been prepared under a Memorandum of Understanding between
the Bureau of Mines, U.S. Department of the Interior, and the Division of
Earth Resources, North Carolina Department of Natural and Economic Resources,
for collecting information on all nonfuel minerals. 
By Eugene C. Baker' and Eldon P. Allen2 
 The value of North Carolina's nonfuel mineral production in 1978 and 1979
added $295 million and $342 million, respectively, to the State's economy.
Stone was the leading mineral commodity in terms of output and value. The
five leading mineral commodities consisting of stone, phosphate rock, sand
and gravel, cement and lithium minerals accounted for almost 90% of the State's
total mineral value in 1978 and 1979. 
 The combined output of stone, sand and gravel, and cement in 1978 was 16%
greater than that of 1977, owing primarily to acce 
lerated building programs in the industrial, commercial, and residential
construction industries. In 1979, the combined production of these commodities
was virtually unchanged from that of 1978. 
 In 1978 and 1979, North Carolina was the leading State in the Nation in
the production of feldspar, lithium minerals, scrap mica, and pyrophyllite.
It ranked second in the output of common clay, crushed granite, and olivine
and third in the output of crushed marble and phosphate rock.
