ABSTRACTThe fundamental objective for this experiment is to study the rocks and minerals using a microscope. Secondly, to identify the cross sections of rocks, minerals and ores. Generally, petrography is the study of rocks and minerals using a microscope. The cross sections are important for the identification of rocks, minerals and ores from this study. Thin section is served as the laboratory preparation of rock, mineral and soil being used with a polarizing petrographic microscope.The experiment was implemented by cutting the sample rocks into a smaller samples using the cutting machine. The samples are then being polished using a piece of sandpaper to remove the bubble layers on the rocks surface. After that, rock samples were glued to the glass slide by using thermoplastic cement. The thin section lapping was set up and then the samples were placed to minimize the thickness to 30m. It were observed by using the microscope by using 4x, 10x, 20x, and 40x magnification. The characteristics of rock samples were analyzed after the observation under microscope. On the other words, it is obviously shown that the sandstone comprising many minerals, pore spaces, matrix and cementation. Rock sample can be referred as sanstone because white colour appeared under the microscope. Also, it shows some properties of metamorphic litho logy, which is pink and brownish colour, denote to the calcite cement and likely contribute of fluid and cement. Thus, study of rocks and min
