541The Mineral Industry of NewJersey 
This chapter has been prepared under a cooperative agreement between the
Bureau of Mines, U.S. Department of the Interior, and the New Jersey Division
of Resource Development, Bureau of Geology and Toj~ography, for collecting
information on all minerals except fuels.

 The continuing decline in the value of New Jersey mineral production was
attributed primarily to the cessation of iron ore mining and to decreased
output and lower unit value of other metallic minerals recovered. Mineral
valuation totaled $72.7 million, 4 percent below that of 1966. A bright note
was the increased output and value of stone and sand and gravel, which reflected
a continuing high level of construction activity. Increased values were recorded
for all nonmetallic minerals except clay and magnesium compounds. 
 Mineral production was reported for all 
counties except Salem. Increased values were reported for 10 counties. Sussex
County showed the greatest increase, due to greater production and value
of stone, manganiferous residuum, peat, lime, and sand and gravel. These
increases more than offset the decreased value of zinc recovered in the county.
Somerset County continued as the leading mineral-producing area, and was
followed, in decreasing order of value, by Sussex, Cumberland, Morris, and
Passaic Counties.
