摘要
The origin of the enigmatic UG-1 chromitites at Dwars River in the eastern limb of the Bushveld Complex has been vigorously debated. The UG-1 chromitites form an anastomosing network of multiple layers that are hosted in poikilitic anorthosites and their formation has previously been explained by depositional, erosional, and intrusive processes. We propose that the UG-1 chromitites formed in respo...
