Figure F85. Large miarolitic cavities filled with smectite (black) and calcite (white) in interval 192-1183A-57R-1 (Piece 9, 62-78 cm). A horizontal 1- to 2-mm-wide vein of calcite, with minor smectite and disseminated pyrite, connects the miarolitic cavities located 63 cm from the top of the section.
