You don’t need to go on a Jules Verne journey down to the center of the Earth, sometimes the center of the Earth is brought up to us! These rocks are examples of 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.

Speleothems

Imagine that there’s a faucet that’s slowly dripping. If the faucet is left to drip long enough, you’ll notice that it will leave behind deposits from the dissolved minerals in the water. Now, imagine if you left your faucet dripping long enough to create a mineral deposit that was a meter-plus tall. This process is the… Continue reading Speleothems
