Figure F10. Close-up photograph showing a graded, redeposited layer of nannofossil chalk with clay and spicules interbedded within the dominant nannofossil chalk with foraminifers (interval 205-1253A-1R-1, 78-104 cm). Parallel lamination, darker color, and lack of bioturbation testify to the current controlled origin of this interval.
