Four environmental provinces are distinguished in the deep South China Sea based on ichna and their relationship to Pinatubo 1991 ash accumulation. Scolicia ichnofabrics along Philippine Islands sand-prone, greenish, oxygen-deficient deposits 3500 m water depth. Abundance size of appear be related quantity quality benthic food, respectively. producers intensely bioturbate ash; below this level, Phycosiphon, Planolites, Thalassinoides may occupy different tiers. In mud-prone Palaeophycus,...
Comparisons between Phycosiphon incertum Fischer-Ooster (1858) and Anconichnus horizontalis Kern (1978) show that these two monotypic ichnogenera do not differ significantly in geometry, size, sediment fill, environmental occurrence. Therefore, taxonomic priority has to be given becomes a subjective junior synonym. The trace fossil is small, highly lobed spreite structure produced by zoned backfill consisting of pale mantle dark core. In few cases, meniscate visible the an extension...

Coarsening increased rates foreland basin foredeep indicate accentuated tectonic activity unroofing since that time. The volume includes ≥1 Neogene was lost via Nicobar to Sunda accretionary wedge.

Summary In the deep sea, burrowing infauna can adapt to variation in sediment texture within < 100–300 years. When there is continuous sedimentation, a bioturbation process also takes place and biogenic trace association found fossil record may be dominated by deeply penetrating burrows. A low-diversity ( Zoophycos ichnofacies) typical. On other hand, when turbidites interrupt process, highly diverse often state that contains organized near-surface traces Nereites ichnofacies).

ABSTRACT A new sea‐level record derived from coastal deposits of the South Vietnam shelf covers deglacial history between 13.0 and 9.0 ka BP. This reveals a relatively constant rate rise matches well with model results based on RSES‐ANU global ice‐sheet model. However, observations reveal significant discrepancy ICE‐5G model, which further questions existence Meltwater Pulse 1B The incised‐valley also complete evolution southern Vietnam. regional records shelf, Mekong Delta Cambodian...
