Contributions to mineralogy

Abstract

The axinite, both, in crystals and laminated masses, is found, as a great rarity, associated with a beantiful rose-colored variety of fowlerite, polyadelphite~ hiotite and barite. The crystals are of a beautiful honey-yellow or pale greenish yellow color, from about 1 mm to 5 mm in size. Spe(~. grav. of the crystals = 3•358, of the laminated masses = 3•306. The axinite crystals are of interest as they have a very unusual habit and also possess some rare planes. The forms which have been observed are as follows, using Naumann's position. a, 100, i-i m. llO, l' x, Ill,-1' 8,201,-2-i X. 021, 2-l b, 010, i-l M, 110, I ' 1", Ill,-I.

Monazite in the granitic rocks of the southeastern Atlantic States: An example of the use of heavy minerals in geologic exploration

“…About 125 analyses of unweathered granitic rocks in Virginia, North Carolina, South Carolina, and Georgia were published as of 1957 (Alfred and Schroeder, 1948;Clarke, 1900;Darton and Keith, 1898;Day, 1898;Genth, 1862;Herrm>ann, 1954;Jones, 1909;Kerr, 1875;Laney, 1910;Lewis, 1893;Pegau, 1932;Phalen, 1904;Pogue, 1909;Sloan, 1908;Steidtmann, 1945;Taber, 1913;Watson, 1902Watson, , 1904Watson, , 1907Watson, , 1909Watson, , 1910Watson and Cline, 1913;Watson and Laney, 1906;and Watson and Taber, 1913). In addition to these, the U.S. Geologi cal Survey has made one analysis for W. R. Griffitts, six for W. C. Overstreet (Overstreet, Yates, and Griffitts, 1963b), and nine for the writer.…”
