Mineral Thin Section

The method involved using.
Mineral thin section. Titanite im colourless or pale brown. Both plane polarized light field width is 1 2 mm. Calcite and dolomite are the only two common minerals that can noticeibly change from low to high relief on rotation in thin section.
May have zones or trails rich in inlcusions of quartz biotite etc which may show s or z shapes. Shape isotropy and relief distinctive. When minerals rocks and fossils cannot be accurately identified by macroscopic observation and testing thin section slides can reveal the compositi.
It is then mounted on a glass slide and then ground smooth using progressively finer abrasive grit until the sample is only 30 μm thick. High 17 40 ve extreme pinky buff colours occasional. Theoretical considerations discussing the interaction of minerals and light the properties of minerals in thin section and the most practical aspects of optical mineralogy.
Minerals in thin section is the perfect supplement for mineralogy optical mineralogy and petrography courses.
