Sep 14, 2021 · Some of the region’s U-shaped “fossil fjords” (called paleofjords by geologists) are visible in this map, composed from elevation data from the Shuttle Radar Topography Mission (SRTM). The map is false-color to emphasize the topography; red areas are the highest elevations, and blue areas are closer to sea level.

Nov 8, 2024 · Namibia is remarkable in terms of its network of c. 300 Myr old fjords, cut by Gondwanan glaciers at high palaeolatitudes during the Late Paleozoic Ice Age (LPIA). A classic suite of structures is preserved on Proterozoic bedrock, including striations, roches moutonnées and other subglacial features within many of these palaeovalleys.

Aug 30, 2021 · We show that U-shaped valleys in northwestern Namibia cut during the late Paleozoic ice age (LPIA, ca. 300 Ma), Earth's penultimate icehouse, represent intact fjord-network morphologies.

Feb 22, 2024 · A Journey into the Namib Desert to Study 300-million-year-old Fjords During the austral winters of 2019, 2021, and 2022, the University of Wisconsin-Milwaukee sedimentology team went deep into one of the oldest and driest deserts on Earth to investigate a well-preserved deep-time landscape generated by glaciers around 300 million years ago.

Sep 21, 2021 · Namibia’s fossil fjords are believed to have acted in the same way as modern fjords in the North. And while fjords in places like Greenland and Norway may be much larger, their appearance is the same as those in Namibia, reflecting the …

Sep 14, 2021 · Fossil Fjords in Namibia. Ice that carved a network of valleys 300 million years ago has long since disappeared, but the original shapes of the valleys remain.

Sep 14, 2021 · Today’s Image of the Day from NASA Earth Observatory features the desert landscape of northwestern Namibia in southwest Africa. The valleys that cut through the plateaus, which were once fjords filled with seawater, are extremely old and well preserved.

Dec 13, 2021 · Some of the region’s U-shaped “fossil fjords” (called paleofjords by geologists) are visible in this map, composed from elevation data from the Shuttle Radar Topography Mission (SRTM). The map is false-color to emphasize the topography; red areas are the highest elevations, and blue areas are closer to sea level.

Dec 6, 2021 · Fjords are glacially carved estuaries that profoundly influence ice-sheet stability by draining and ablating ice.

Mar 13, 2025 · An assemblage of features cut into crystalline bedrock in northern Namibia were produced approximately 300 million years ago during the Late Palaeozoic Ice Age (LPIA) and exhibit an outstanding array of structures contained within deep palaeo-fjords, capped by glaciogenic rocks of the basal Dwyka Group.
