Pulverized quartz clasts in gouge of the Alhama de Murcia fault (Spain): Evidence for coseismic clast pulverization in a matrix deformed by frictional sliding
COVER: Fossilized vascular land plant exposed on a bedding plane within a riverbank exposure of hyper-enriched black shale at the Peel River locality, Yukon, Canada (field of view is 14 cm wide). The Middle Devonian age of this locality suggests that the woody fossils belong to the extinct class Cladoxylopsid. The primary carbonaceous materials were replaced by pyrite and millerite permineralizations within a sediment-starved and microbially active depositional environment. See Gadd et al., “A Middle Devonian basin-scale precious metal enrichment event across northern Yukon (Canada)”, p. 242–246.
