ATLANTA - A layer of quartz grains found in an east Georgia kaolin mine have been traced to the impact of a giant asteroid that crashed near the mouth of the Chesapeake Bay 35 million years ago.
The 54-mile-wide (86-kilometer-wide) crater left by the meteor, the sixth-largest in the world, has previously been identified as the source of a rare mineral called Georgiaite. Small, glassy, olive-green beads of it have been found for decades in more than a dozen middle Georgia counties.
They are a type of impact-produced natural glass called tektite.
