Cathodoluminescence Map of Zircon
Detailed Description
Here's an image of a zircon grain in an igneous rock called rhyolite. The scan shows a melt inclusion in an inherited core that is about 100 million years older than the age of the host rhyolite, which can show us the conditions of the molten mix that would later give rise to the rhyolite.
