Calcareous Nanofossil of Post-Gondwana Sequence in Southern Banda Arc, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2021
The presence of calcareous nannofossils in samples of the Post-Gondwana sequences (Kolbano and Viqueque sequence) gives guidance about the relative age of the study area located in the Outer Banda Arc, namely Timor, Rote, and Sawu Island.

Enhancing event stratigraphic correlations in the ultra‐deep Japan Trench using XRF‐CS cluster‐based chemostratigraphy

The Depositional Record, Volume 12, Issue 1, February 2026.
Cluster‐based chemostratigraphy using XRF‐CS enables high‐resolution correlation of event deposits across contrasting depositional settings in the Japan Trench. This approach reveals previously unrecognised events and compositional heterogeneity, offering new insights into sediment provenance and earthquake‐triggered deposition, with implications for ...
