31. Sandstone classifications are typically done by point-counting a thin section using a method like the Gazzi-Dickinson Method. 32. The approach relies heavily on the geological principles of optical mineralogy, thin section petrography and soil micromorphology. 33. After this the thin section mounted slide is stained and a protective cover slip is mounted on it. 34. Which means that the velocity of light changes in crystallographic direction, this is easily identifiable in thin section . 35. This thin section boils, drys, and carbonizes, then breaks in half, creating an electric arc full of carbon ions. 36. In a thin section it has a high surface relief and will have sharp boundaries with the surrounding medium. 37. Thus, this process is capable of bringing manufactured parts back into design tolerance limits and form shaping thin section parts. 38. DX test, a pathologist will send the tumor block or several thin sections of the tissue sample to Genomic Health. 39. Earth usually crosses a thin section of the Leonids trail; perhaps 10 meteors per hour streak across the night sky. 40. Recognising a crenulation in a rock may require inspecting the rock with a hand-lens or petrographic microscope in thin section .
