Figure F32. Microstylolite produced by pressure solution of foraminifer chalk (Subunit IC; Oligocene; Sample 192-1183A-20R-CC, 2-6 cm; plane-polarized light; field of view = 1.4 mm; photomicrograph ID# 1183AS_1). Foraminifers are truncated by enhanced dissolution adjacent to the thin clay seam in the middle of the image.
