Figure F13. Enlarged view of hematite fronds in jasperoid Sample 193-1189B-11R-1 (Piece 3, 14–16 cm; CSIRO 142714; see Fig. F12). The dark fronds are planar and dip steeply into the section. They are aggregates of very thin hematite flakes with subround outlines as seen on the right. Some transparent flakes are orange colored and possibly goethite, but the bright red reflectivity of the sample indicates presence of much hematite. Two tiny apatite prisms are included in quartz at the upper left. Width of view = 0.25 mm; ordinary light.
