Late Cenozoic Sediment Provenance in the Northern Canterbury Basin, Aotearoa New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.Late Cenozoic strata of the northern Canterbury Basin record uplift and erosion of mountain ranges adjacent to the transition from oblique subduction to strike‐slip on the Australian–Pacific plate boundary. Using the provenance of conglomerate clasts and sandstone samples, we reconstruct sediment transport pathways and, by inference, exhumation and ...

Basin Research, Volume 38, Issue 6, November‐December 2026.Statistically significant cyclicity preserved in Joggins Formation rhythmites is most consistent with tidal modulation. These findings provide new quantitative evidence that tidal energy propagated into the Cumberland Basin, supporting interpretations of marine connectivity during Late Carboniferous deposition.

, 2015 The Late Neoproterozoic assembly of western Gondwana played an important role in the subduction of oceanic and continental lithospheres. Such event was also a source of arc magmatism, reworking of cratonic margins and development of ultra-high pressure ...

On the Origin of the Tingidae (Insecta, Heteroptera)
Zoologica Scripta, Volume 55, Issue 6, Page 876-892, November 2026.ABSTRACT The hypothesis of a Gondwanian origin of the family Tingidae (Insecta, Heteroptera) has been promoted and seems to be generally accepted by specialists. However, the area of emergence and diversification of the clade, South American or Australian, is still debated and cannot be solved without integrating Vianaidinae, a subfamily considered as ...
