Stunning 3D Rock Images Revealed in New Lab

This 3D model reveals the inside of an oolite – a rock containing sand grains coated in concentric layers of calcium carbonate.

 PRINCETON, N.J. — A geologist and an architect standing in a lab may sound like the start to a very nerdy joke, but a pair of these professionals have joined together to revolutionize the way scientists study structures, such as fossils, inside rocks.

Geologists use a variety of techniques to analyze fossils and other features trapped inside Earth's rocky layers. The most basic technique, dating back to the 19th century, involves slicing away layers of rock, taking pictures of each layer, and then recreating the full 3D shapes by connecting dots between images. But this method is tedious and prone to human error.
