located about 15 miles south of Columbus, Tex., in Colorado County, has a
capacity of 750 tons of finished sand and gravel per hour. 
 Sodium Sulfate (Natural).—Ozark-Mahoning Co. obtained sodium-sulfate
brines from shallow wells drilled into alkali-lake beds in Gaines and Terry
Counties. The brines were processed into salt cake at the company's plants
near Brownfield and Seagraves. Output and total value increased during 1972.
Salt cake is used in the manufacture of kraft paper, glass, detergents, and
other products. 
 Stone.—Production of all stone, crushed and dimension, in Texas during
1972 totaled 49.3 million short tons. The output was 20% greater than that
of 1971. Wise County led in stone production, followed by Williamson, Bexar,
Comal, and Calhoun Counties. 
 Production of crushed stone, reported from 189 quarries during 1972 accounted
for nearly all of the stone output. Eightysix percent of the crushed stone
consisted of limestone and dolomite, and 10% consisted of shell. The remaining
4% comprised basalt (traprock), granite, marble, marl, metarhyolite, sandstone,
and quartzite. Crushed stone output increased almost 20% in 1972, with a
7% increase in total value. The 19% dedine in shell production and the 56%
drop in output of crushed sandstone and quartzite were offset by a 34% increase
in the production of crushed limestone and dolomite. The crushed stone was
used as concrete aggregate and other aggregate, road ' base stone, railroad
ballast, agstone, riprap, flux stone, terrazzo chips, whiting, raw material
in preparing cement and lime, and for other purposes. 
 Dimension stone was produced at eight quarries in 1972. Granite for use
as dimension stone was obtained from three quarries in Burnet County and
from one quarry in Liano County. Limestone was produced for use as dimension
stone at one quarry in Gillespie County, two quarries in Jones County, and
one quarry in Williamson County. The dimension stone was prepared as rough
blocks, sawed and cut stone, house stone veneer, flagging, and monument stone.

 Gifford-Hill & Co., Inc., a major producer of aggregate materials in
Texas, began production at its enlarged crushed stone plant near Bridgeport
in Wise County. With a yearly production capacity of 3.2 million tons of
limestone, the plant is one of the largest crushed-stone facilities in the
United States. The wet process used at the plant eliminates nearly all dust-related
air pollution. 
 In Johnson County, Cleburne Crushed Stone Co., Inc., opened a new limestonecrushing
plant near Cleburne. Another limestone producer in Johnson County, Rangaire
Corp., parent company of Texas Lime Co., announced that it had increased
its limestone reserves by 6.2 million tons with the purchase of 1,800 additional
acres of land in the county. 
 In Bell County, Belton Minerals Co. announced the purchase of a crushed-limestone
plant near Belton that formerly was owned by Belton Development Co. Also
in 1972, Texas Quarries, Inc., a producer of dimension limestone in Williamson
County, was acquired by Kingstip, Inc., parent company of the Featherlite
Corp., a clay producer and manufacturer of lightweight aggregate.
