Figure F5. Close-up photograph showing the lithologic boundary between the forearc prism sediment (lithostratigraphic Subunit P1B), represented here as a darker claystone, and the underthrust sediment (lithostratigraphic Subunit U1A), which is seen here as a lighter more silt-rich claystone (interval 205-1254A-15R-2, 128-145 cm; 360.6 mbsf).
