Page 40 - 0.21 Total 99-77 Mr. Brooks has given the following petrographic data on the granite from this locality: "Contains microcline, some plagioclase, abundant pyroxene partly altered into chiefly uralite and chlorite, some biotite with frequent inclusions of rutile, much blue vitreous quartz, apatite, zircon and magnetite.
Page 149 - therefore strictly residual deposits enclosed in the decay derived from the rocks containing the manganese. In still others, the ores are regarded as entirely secondary deposits, and their present distribution in workable form has been determined largely by chemical and physical conditions, rather than by the outcrop of beds especially rich in manganese. Modifications of the two last statements of
Page 48 - Only the oxides of manganese occur in the Cartersville district. Of these, pyrolusite and psilomelane greatly predominate, with some manganite and braunite, and much of the earthy oxide, wad. These
Page 28 - The area includes the ten northwest counties of the State; and it is separated, on the east and south, from the Crystalline Area by the Cartersville overthrust fault. It forms a part of the southern extension of the great Appalachian Valley, southwestward into Middle Alabama. TOPOGRAPHY.—The region, as
Page 48 - invariably show small percentages of manganese; and, conversely, the manganese ores show varying percentages of iron, with intermediate gradations, in which the two oxides are nearly equal in amount, forming a good grade of manganiferousiron ore. These gradations are brought out in the following analyses of samples of the ores from the district: — Lot
Page 48 - State to this area. The deposits of bauxite and barite are of minor importance, only; since the former is but sparingly found near the limits of the district, and the latter, while more abundant is not sufficiently concentrated to admit of profitable working. The relations of the manganese to the bauxite deposits are
Page 61 - is usually sufficiently concentrated, to be generally free from admixed clay and other foreign materials: and it requires practically little or no washing before shipping. Analyses of two separate carloads of this ore were kindly furnished the Survey by Capt. John J. Calhoun, of Cartersville, Ga.; they are as follows: — Per Cent. Per
Page 94 - The property was first opened in 1867, and is one of the oldest manganese mining properties in the State. Prior to the leasing of the property by Mr. EH Woodward in 1885, it was worked by the Bartow Mining and Manufacturing Company. From 1867 to 1885 inclusive, 5,500 tons of ore are said to have been mined.

Deep-red Clay. 2. Red, Mottled Clay Filled with Chert Fragments. Penrose states, that the ore is sometimes found in place on this tract.
