... as six samples of a footwall sill, the Taylor’s Koppie dike, that was considered a possible feeder zone to the lobe, and through a massive sulfide lens in the footwall of the lobe at Ndzongiseni. We show that most of the Insizwa cumulate rocks contain small amounts of cumulus sulfides. The sulfides...

... (Fig. 1a ) is a pre-Missi diabase dike whose mineralogy is identical to that of the Amisk basalts. This paleosol occurrence is also characterized by well-developed corestones, but does not have any maroon paleosol, which might have been removed locally by erosion before the deposition of the Missi...
