Benthic foraminiferal plate from LP21

The LP21 benthic plate is an assemblage-level environmental dataset, not a collection of independent depth markers. Relative abundance, diversity, wall composition, preservation and evidence of transport should accompany identifications.

Geological interpretation and evidential boundary

The LP21 benthic plate is an assemblage-level environmental dataset, not a collection of independent depth markers. Relative abundance, diversity, wall composition, preservation and evidence of transport should accompany identifications. Fine-grained host lithology may favour quieter-water deposition, but low-energy substrate, reduced oxygen or high organic flux can shift benthic composition independently of bathymetry. The environmental inference should therefore be framed as a probability distribution across shelf-to-bathyal settings, narrowed only where several ecologically coherent taxa dominate and sedimentological evidence agrees. A mixed population is geologically meaningful: it may record downslope transport or reworking within the Halang turbidite system rather than analytical failure.
