PREPARATION OF ROCK THIN SECTIONS CoNrrxrs Abstract Most of the thin sections made from ordinary firm rock material can be finished on the rotating lap Some thin sections show signs of fraying at the edges and then it is necessary to continue the grinding by hand on a piece of plate glass with f600 optical alundum The ability to decide when the thin section has been ground to the
Detailed Description Photomicrograph of sample 09RDWES301 an 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
