Neoproterozoic glacial palaeolatitudes: a global update

New stratigraphic, geochronological and palaeomagnetic constraints allow updates to be made to a synthesis of Neoproterozoic glacial palaeolatitudes, including modifications to some reliability estimates. The overall pattern of a Neoproterozoic climatic paradox persists: there is an abundance of tropical palaeolatitudes and near to complete absence of glaciogenic deposits demonstrably laid down...

Kinematics of back‐arc inversion of the Western Black Sea Basin

[1] Back‐arc basin evolution is driven by processes active at the main subduction zone typically assuming the transition from an extensional back‐arc, during the retreat of a mature slab, to a contractional basin, during high‐strain collisional processes. Such a transition is observed in the Black Sea, where the accurate quantification of shortening effects is hampered by the kinematically uncl...

Long-Term Stability of Back-Arc Basin Hydrothermal Vents

Since the discovery of hydrothermal vents 40-years ago, long-term time-series have focused on mid-ocean ridge systems. Based on these studies, hydrothermal vents are widely considered to be dynamic, ephemeral habitats. Under this premise, national, and international regulatory bodies are currently planning for the commercial mining of polymetallic sulfide deposits from hydrothermal vents. Howev...

Submarine back-arc lava with arc signature: Fonualei Spreading Center, northeast Lau Basin, Tonga

[1] We present major, volatile, and trace elements for quenched glasses from the Fonualei Spreading Center, a nascent spreading system situated very close to the Tofua Volcanic Arc (20 km at the closest), in the northeast Lau Basin. The glasses are basalts and basaltic andesites and are inferred to have originated from a relatively hot and depleted mantle wedge. The Fonualei Spreading Center sh...
