These are (1) near Keenburg and (2) Chattanooga, Tenn.; (3) Wilkinson County, Georgia; (4) from Jacksonville, Ala., to Cartersville, Ga.; and (5) in southwestern New Mexico. The Keenburg deposit is found in clays which have been derived from Paleozoic (Cambrian) shales. (2) The Chattanooga deposits are found as deposits in clays which were derived from Paleozoic (Silurian) shale. (3) The Wilkinson County, Georgia, deposits occur in beds near the contact of the Lower Cretaceous and Tertiary beds, and (4) the southwestern New Mexico deposits were probably derived from the alteration of basic volcanic rock.

BUILDING AND STRUCTURAL STONES The building and structural stones of Arkansas can be divided into three general classes: (1) Syenite or "granite", (2) sandstone and quartzite, (3) limestone, marble and dolomite. Syenite Arkansas syenite, which is technically a nephelite syenite or "granite," is found in four different localities in the State, as follows: (1) Pulaski County, south of Little Rock; (2) Saline County, in the vicinity of Bauxite; (3) Garland County, near Potash Sulphur Springs; (4) Hot Spring County, at Magnet Cove. The location of these four areas is shown on the map in the center of the book. The total area of this exposed rock is about thirteen square miles. The Arkansas syenite occurs in two varieties known as "blue granite" or Pulaskite, and "gray granite" or Fourchite. The rock is somewhat similar to granite except that it contains very little quartz. These syenites are all igneous rocks which were intruded through the thick masses of sedimentary rocks. Orthoclase, which is a potash feldspar, is the most important mineral in the rock. It also contains hornblende, augite, biotite, syenite, etc. The chemical constituents of Pulaskite and Fourchite are as follows: The physical properties of the two syenites of the Pulaski County area are as follows: Most of the Fourche Mountain area is made up of Pulaskite or blue granite. The gray granite is found only in comparatively small areas around the edges of the main mass. The average physical properties of the Saline County syenite are as follows: Color Crushing strength (per square inch in 2-inch cubes), lbs. Ratio of absorption White gray 22,350 lbs 1:656 2.603 Specific gravity Weight per cubic foot 162.68 lbs. The physical properties of the nephelite syenite from Magnet Cove and Potash Sulphur Springs has not been determined in detail, but they will very probably not be radically different from the above qualities. The Arkansas syenites have exceptional building strength and weather-resisting qualities and are valuable as building stones, paving stones, trap rocks, and for concrete aggregate. The rock sells for from $1.00 to $1.50 per cubic foot in the rough. There has been comparatively little development of the granite quarrying industry in Arkansas. Granite has been quarried from five different points on the north flank of Fourche Mountain. These are: (1) The Ward quarry (now Galloway), (2) Moore quarry, (3) Miller-Butterworth, (4) Braddock quarry, (5) Monahan & Sons. The Ward and Braddock quarries have a capacity of 15,000 cubic feet per year of rough stone. One crushing plant and one quarry are in intermittent operation at the present time. These are: (1) The Little Rock Marble Company, Zeb Ward, manager, Home Life Building, Little Rock, Ark., and (2) The Fairview Rock Company, W. W. Bean, manager, Little Rock, Ark. There are no figures available showing the output of granite quarries. These figures are combined with those for rock which includes building stone of all kinds. The "stone" output for the State is as follows, according to the figures of the U. S. Geological Survey: 1. 2.

Science obtainable from The Science Press, Grand Central Terminal, New York City. Sandstone and Quartzite There are immense quantities of sandstone in the Paleozoic area of Arkansas. The Arkansas Valley contains practically unlimited supplies of sandstone in the Jackfork and Atoka formations and, to some degree, in the coal measure beds. The Ouachita Mountain region contains sandstone in the Stanley shale, the Hot Spring sandstone, the Blaylock sandstone, and the Blakeley sandstone. The Boston Mountain and Ozark Plateau region contains practically unlimited amounts of sandstone in the lower portion of the Winslow formation, in the Hale formation, the Batesville sandstone, the St. Peter's sandstone, and the King's River sandstone. |
