Friday fold: Ferruginous sediments in Barberton Mountain Land
Posted by Callan Bentley
Today, I dug into my photo archives looking for folds that (I think) I haven’t shared before, and came across these two, from the beginning of the R40 road outside of Barberton, South Africa, on the road that leads up into Barberton Mountain Land, and toward the border with Swaziland.
The rocks here are sedimentary layers, and they show some relatively minor folding: Honestly, they’re pretty pristine for Archean aged deposits of mud, silt, and sand!
Happy Friday!
