Abum caption: Metamorphic mineral assemblages of slightly calcic pelitic rocks in and around the Taconic allochton. Photomicrographs of sample 191-1 showing chlorite (Ch) rimming magnetite (Mt) (plane-polarized light). A "ghost" crystal of chloritoid ("Cd") is also shown. The magnetite and chloritoid are interpreted to be relicts of an erlier episode of metamorphism. Southwestern Massachusetts and adjacent Connecticut and New York. ca. 1966. Published as figure 19 in U.S. Geological Survey. Professional paper 1113. 1981.
