New rock formation discovered in Colorado

23 septiembre 2014

An astonishing new rock formation has been revealed in the Colorado Rockies, and it exists in a deeply perplexing relationship with older rocks. Named the Tava sandstone, this sedimentary rock forms intrusions within the ancient granites and gneisses that form the backbone of the Front Range. The relationship is fascinating because it is backward: ordinarily, it is igneous rocks such as granite that would that intrude into sedimentary rocks.
