Parallel-laminated sandstone beds used as turbidite evidence

Two close views show thin parallel lamination and grain-size contrast.

Parallel-laminated sandstone beds used as turbidite evidence

Figure content

Two close views show thin parallel lamination and grain-size contrast.

Interpretive role

Retitle as laminated beds; remove specific Bouma divisions unless diagnostic structures are shown.

Technical context

Panel A and B both appear dominated by parallel lamination. Assigning Tc requires ripple cross-lamination; assigning Tb requires planar lamination. The current Tc/Tb distinction is unsupported by the visible photographs.
