Figure F17. Summary of lithologic characteristics of the subunits of Unit II at Site 1184, based on the facies defined in Table T2, . "Wood" indicates approximate intervals in which pieces of wood were found. The uppermost interval is represented by two pieces, 1-2 cm long and <2 mm thick. At the other three wood-bearing levels, pieces of wood are as long as 6 cm. In the chromaticity plot, a = the variation between green (negative) and red (positive), and b = the variation between blue (negative) and yellow (positive) (Blum, 1997).

"Wood" indicates approximate intervals in which pieces of wood were found. The uppermost interval is represented by two pieces, 1-2 cm long and <2 mm thick. At the other three wood-bearing levels, pieces of wood are as long as 6 cm. Red shading in the Graphic lithology column indicates red or yellow oxidized intervals. In the chromaticity plot, a = the variation between green (negative) and red (positive), and b = the variation between blue (negative) and yellow (positive) (Blum, 1997).
