5. This small Jack Hills zircon (50 micrometers is about the width of a human hair) crystallized slowly. The crystal grew from the core (left) to the rim (right). As crystals form, they incorporate chemicals from their surroundings. (Image courtesy Bruce Watson, Rensselaer)
The roughly 80-kilometer-long formation is a collection of bits and pieces of greatly eroded sedimentary and metamorphic rocks such as chert, sandstone, and quartzite.  
Individual crystals of zircon within the rocks are 4.4 billion years old, only 150 million years or so younger than the age of the Earth itself. These crystals are the oldest fragments of the Earth yet found. (Photograph copyright Bruce Watson, Rensselaer)
