Morgan Schaller at the Rensselaer Polytechnic Institute in New York and colleagues found marble-like glassy spherules, known as microtektites, which they believe to be fragments of debris scattered into the air after an object collided with the Earth some 55 million years ago.This is known as the Paleocene-Eocene Thermal Maximum (PETM), one of the most dramatic climate events known to science.But in general, says Richard Carlson, a geochemist from Carnegie Institution for Science in Washington DC, “finding really old rock has been almost impossible.” Not that Carlton and his colleague, Jonathan O’Neil of the University of Ottawa, Canada, actually found a new trove of super-ancient rocks.Instead, in a study published in Science, they looked for isotopic traces of earlier rocks in ones not quite so ancient.Their chemical composition says they didn’t erupt directly from the mantle, but were instead formed from pre-existing basalts that were pulled below the surface, heated, and then recycled back to the surface to form the granites we see today.In the process, the physical remnants of the older rocks were destroyed, but their isotopic signatures remain.

These remnants suggest that tectonic processes in the planet’s first 1.5 billion years may have been very different to what we know today.On the flip side, a membership can get to be at least a little bit on the expensive side – especially if you’re not using any coupons.Hopefully, by the time you’re done with this quick guide, you’ll have an understanding as to where you can get the best offers, what kind of free trial opportunities you should stay away from, and how to get the most out of your experience.
