Sandstones in thin section - Geological Digressions
WebToday, most optical mineralogy involves examining thin sections with a petrographic microscope. Petrographic microscopes have polarized light sources that illuminate a thin section. We examine thin sections in two modes: using plane-polarized light or using cross-polarized light. WebSECTION IV-Thin-sectioning . Part I - Thin section machine. (Fig. 11) CAUTION: Lab coat, eye protection, and ear protection must be worn for Section IV. 1. Turn on pumps and motor to the thin section machine. 2. Using the black knob, turn on the water to the cutting blade. 3. Place the sample into the holding arm of the cutting blade. hotel california randy meisner
Identification Tables for Common Minerals in Thin Section
Thin sections are prepared in order to investigate the optical properties of the minerals in the rock. This work is a part of petrology and helps to reveal the origin and evolution of the parent rock. A photograph of a rock in thin section is often referred to as a photomicrograph. Thin sections are also used in … See more In optical mineralogy and petrography, a thin section (or petrographic thin section) is a thin slice of a rock or mineral sample, prepared in a laboratory, for use with a polarizing petrographic microscope, electron microscope See more Fine-grained rocks, particularly those containing minerals of high birefringence, such as calcite, are sometimes prepared as ultra-thin sections. An ordinary 30 μm thin section is prepared as described above but the slice of rock is attached to the glass slide … See more Description In thin section, when viewed in plane polarized light (PPL), quartz is colorless with low relief and no cleavage.
