| 3 | Structure of silicate minerals: neso-, soro-, cyclo-, iono-, phyllo- and tecto-silicates and their bearing on properties of minerals. Study of the following mineral groups/minerals with reference to structure, PT - stability, physical, chemical and optical properties, and their mode of occurrence: quartz, feldspar, feldspathoid, pyroxene, amphibole, olivine, mica, clay minerals, garnet, alumino-silicates, staurolite, epidote, zircon, sphene, zeolite, carbonate, and phosphates. |
|
| 4 | Sampling and sample preparation; thin section and polished section making. Sample etching, staining and modal count techniques. Technique in photomicrography. Brief introduction to: principles and geological application of thermo-luminescence; atomic absorption spectrophotometry; ICP-MS; mass spectrometry; x-ray diffractometry; electron microscopy and electron-probe microanalysis. |
