233The Mineral Industry of Louisiana This chapter has been prepared under a Memorandum of Understanding between the Bureau of Mines, U.S. Department of the Interior, and the Louisiana Geological Survey, for collecting information on all nonfuel minerals. By Murphy E. Hawkins' and Charles G. Groat2 The Louisiana nonfuel mineral industry continued to make an important contribution to the State's economy, producing $356 million in 1978 and $455 million in 1979. Salt and sulfur were the most significant raw minerals produced in terms of value. During the 1970's, Louisiana consistently was ranked either first or second among the States in output of these two important industrial minerals. Important to the State and regional economies was the production of notable quantitites of cement, clays, gypsum, lime, sand and gravel, and stone.~ Table 1.—Nonfuel mineral production in Louisiana' 1977 1978 1979 Value Value Value Mineral Quantity (thousands) Quantity (thousands) Quantity (thou sands) Clays thousand short tons — Salt do~ Sandandgravel do.~ Stone (crushed) do_ — — — Sulfur(Frasch) thousand metric tons. — Combined value of cement, gypsum, lime, sand and gravel (industrial, 1979), and values indicated by symbol W Total 401 13,201 21,987 9,710 2,494 XX $785 96,878 50,790 26,920 W 174,912 517 14,263 22,010 9,130 1,984 XX $4,786 110,472 56,080 26,921 W 157,996 416 14,207 220,446 W 2,858 XX $6,073 113,167 254,081 W W 281,955 XX 350,285 XX 356,255 XX 455,276 W Withheld to avoid disclosing company proprietary data; value included in "Combined value" figure.
