Polyframboidal pyrite of the Rochelinval pyrite beds (Belgian Ardennes)
Abstract
A section of the Revinian near Rochelinval (Belgian Ardennes) shows four beds of “quartzite” (greywacke) which contain concentrated bands of polyframboidal pyrite: other beds contain a little dispersed polyframboidal pyrite. The concentrated bands were formed by submarine reworking of superficial, turbidite sediment which, when it was recently deposited, was of a type generally similar to that giving the other quartzites in the succession. The occurrences, and explanation offered are similar to those for a Silurian turbidite succession in North Wales, and indicate the possibility of a fruitful field of research into the sedimentology of the Lower Palaeozoic rocks of Belgium, despite the strongly tectonised and metamorphosed aspect of these rocks.
