A Continuous 150‐kyr Record of Geomagnetic Field Variations From Lake Chala, Eastern Equatorial Africa

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract Records of geomagnetic field variations from continental Africa are sparse yet provide a key dating tool for low‐latitude paleoclimatic changes. Long‐lived tectonic and crater lakes in eastern tropical Africa potentially provide important, long (>100,000 years, kyrs) and continuous sedimentary records of African monsoonal climate over past ...

Characterisation and Architecture of Subsurface Strata in the Whatcom Sub‐Basin, Georgia Basin, Canada and USA

open access: yesBasin Research, Volume 37, Issue 2, March–April 2025.
In the Paleogene and with the docking of Siletzia on North America's western margin, the Georgia Basin transitioned from a forearc basin to a forearc depression, and this drove a major re‐organisation of depositional environments and paleodrainages in the region. ABSTRACT Outcrops of sedimentary strata that infill the Georgia Basin, Canada and USA have
