A New Geological Map of the Marginal Basins of Eastern Papua New Guinea: Implications for Crustal Accretion and Mineral Endowment at Arc–Continent Collisions Open
Accretion of island arc terranes is a fundamental process of crustal growth and the formation of new continents. Convergent margin tectonics, both compressional and extensional, in accretionary orogens also control the origin and distribut…

A new geological map of the Lau Basin (southwestern Pacific Ocean) reveals crustal growth processes in arc-backarc systems Open
A 1:1,000,000-scale lithostratigraphic assemblage map of the Lau Basin (southwestern Pacific Ocean) has been created using remote predictive mapping (RPM) techniques developed by geological surveys on land. Formation-level geological units…

Shallow Seismicity and the Classification of Structures in the Lau Back‐Arc Basin Open
Back‐arc basins open in response to subduction processes, which cause extension in the upper plate, usually along trench‐parallel spreading axes. However, global seismic databases reveal that the majority of seismic events in the Lau Basin…

The Current State of Global Activities Related to Deep-sea Mineral Exploration and Mining Open
Deep-sea mining is seen as a potential way to provide future secure metal supply to global markets. The
\ncurrent rush to the seafloor in areas beyond national jurisdiction indicates that sound knowledge of the
