    Detailed Description. Photomicrograph of sample 09RDWES301an andesite collected during the Redoubt 2009 eruption. A rock thin section is created by gluing a small piece of rock onto a glass slide then grinding it down to a thickness of 30 microns (the average human hair is about 100 microns in diameter) so that light shines through it when examined under the microscope.
