Summary

[edit]
Description
English: Precambrian-Pennsylvanian nonconformity at Red Rocks Amphitheater, near Denver, Colorado, USA. The rocks below the geologist's right hand are granitic gneisses and migmatites of the Idaho Springs Formation (late Paleoproterozoic, 1.7 billion years). The rocks above that are tilted, hematite-rich conglomerates, arkoses, and sandstones of the Fountain Formation (Pennsylvanian-Permian). 1.4 billion years of missing time are repesented by this unconformity.
