Figure 16. Inferred sequence of events preceding and following accumulation of the Fetais deposit. The massive sulfides were deposited within a graben, on a footwall of rhyolite A and locally rhyolite B. Within the graben, rhyolite C was laid down on top of the sulfides in most places, followed by cherts. Where rhyolite C pinches out laterally, the cherts directly overlies the massive sulfides. The cherts are overlain by shales and fine-grained turbidites of the Paraiso formation, then the Culm flysch.
