Terra Nova, EarlyView.ABSTRACT Thin, discontinuous, organic‐rich oil shale beds in the siliciclastic‐evaporitic Salt Range Formation (SRF) of Pakistan are of approximate Neoproterozoic to Cambrian age based on stratigraphic constraints. The beds are enriched (26–43 wt.% total organic carbon, TOC) in aliphatic organic matter (OM) of low thermal maturity despite their ...

Gold-base metal mineralization of the Mikheevsky (Novonikolaevsky) porphyry copper ore cluster, South Urals [PDF]
МинералогияThe paper describes different types of base metal mineralization of the Mikheevsky (Novonikolaevsky) ore cluster (South Urals, Russia). At the Mikheevskoe porphyry copper deposit, goldbase metal mineralization occurs as subepithermal veins up to 30 cm ...

Terra Nova, EarlyView.ABSTRACT Although central Brazil hosts significant ion‐adsorption rare earth element (REE) deposits associated with A‐type granites, their coeval volcanic counterparts have been largely overlooked as exploration targets. This study demonstrates that acidic metavolcanic rocks of the Araí Group share strong radiometric, geochemical and mineralogical ...

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 ...
