WebScale box in millimeters. Undulose extinction in quartz. Extinction is a term used in optical mineralogy and petrology, which describes when cross-polarized light dims, as viewed through a thin section of a mineral in a petrographic microscope. WebBear in mind that interference color in thin-section can be much lower than the theoretical maximum, depending on grain orientation. Judge birefringence by the highest color you see for that mineral, and check minerals with somewhat higher birefringence if you can't find an exact match. Weakly-colored minerals can sometimes be so pale they ...
WebThe Felspar Plagioclase minerals also show twinning on laws found in Monoclinic Felspars such as Carlsbad, Manbach and Baveno laws. The twinning in these felspars being generally of repeated lamellar type is difficult to recognize in hand specimens and requires preparation of thin sections for study under microscope.
