Black shale deposition in an Upper Ordovician–Silurian permanently stratified, peri-glacial basin, southern Jordan
The Lower Palaeozoic (Upper Ordovician-Silurian) succession of North Africa contains one of the world's most prolific black shale source rocks, yet the origin of these rocks remains contentious. The black shale of the Batra Formation in Jordan was deposited at high palaeolatitude during rapid H...
