| Description | Lower Devonian monomict-quartzose coarse-grained clastics are interpreted as the deposits of an alluvial fan built up mainly by catastrophic sheetfloods. The main sources were probably granites and gneisses, other components were derived from rhyolites, older siliciclastics sediments and low-grade metamorphic rocks. Rapid uplift, erosion dominated by mechanical weathering and multiple redeposition are supposed within the drainage basin. The flat alluvial fan was only slightly reworked and eroded during subsequent non-catastrophic overland flows (sedondary processes). |
