The Great Unconformity is a major gap in the geologic record where more than a billion years of Earth's history appear to have been erased.

Scientists have long debated what geologic forces may have caused so much of the rock record to vanish. One theory proposes that during the icy Cryogenian Period, about 700 million years ago, a Snowball Earth glaciation event eroded kilometers of continental crust. The other attributes tectonic uplift from the formation and breakup of supercontinents as the main cause of erosion.

A new study by researchers including Lamont-Doherty Earth Observatory geologist Nicholas Christie-Blick supports the latter theory: Tectonic forces associated with early supercontinent formation were largely responsible for the Great Unconformity.

One reason to hire a geologist:

The soil keeps shifting in Rancho Palos Verdes, Calif. For the right buyer, that presents a great opportunity, at least for the time being.

What you can do with a little elbow grease and some talented people:

A quiet hallway on the first floor of Missouri S&T's McNutt Hall is home to what could once have been considered thousands of hidden gems — but after recent updates to the Missouri S&T Mineral Museum, many have emerged from hiding and are now sparkling.

An elegant and simple explanation for something that we all need to understand:

The real threat to a secure and sustainable supply of rare earths is not that they are scarce, but that so much is wasted.

For decades, Greenland, through the Geological Survey of Denmark, has been inviting foreign investment and several Canadian and European companies are operating there now. Note the dates on these brochures. The next time a world leader threatens to invade Greenland in order to control the mineral production, you might ask "why not just stake a claim?"
