A xenolith is a fragment of rock that becomes enveloped by magma without being melted or incorporated into it. In these… Continue reading A journey to the center of the Earth | Peridotite xenoliths
An unconformity is an erosional or non-depositional gap in the geologic record. They typically form when an older layer is subject to a period of erosion before the deposition of new sediments. This road cut near Payson, Arizona shows a pretty cool unconformity. Can you find where it is? Check the jump below to see… Continue reading Can you find the unconformity?
