Pg. 30. Used informally as migmatite of Kennesaw Mountain of the allochthonous assemblage. Hurst (1952, unpub. MS thesis, Emory Univ., 165 p.) used the name "Kennesaw Mountain gneiss" for rocks he included in his migmatite category. McConnell and Abrams, 1984 (Georgia Geol. Survey Bull., no. 96, 127 p.) proposed formalized the name as Kennesaw Gneiss Member of their Laura Lake Mafic Complex. Usage is informal in this report because authors don't believe it belongs with Laura Lake Mafic Complex. Report includes geologic map and correlation chart. [See entry under Kennesaw Mountain.]
