2. List of free geology software - Wikipedia

   en.wikipedia.org/wiki/List_of_free_geology_software

   This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.

3. Thin section - Wikipedia

   en.wikipedia.org/wiki/Thin_section

   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 and electron microprobe. A thin sliver of rock is cut from the sample with a diamond saw and ground

4. Point counting (geology) - Wikipedia

   en.wikipedia.org/wiki/Point_counting_(geology)

   In geology, point counting is a method to determine the proportion of an area that is covered by some objects of interest. In most cases the area is a thin section or a polished slab.

5. Ceramic petrography - Wikipedia

   en.wikipedia.org/wiki/Ceramic_petrography

   Ceramic petrography (or ceramic petrology) is a laboratory-based scientific archaeological technique that examines the mineralogical and microstructural composition of ceramics and other inorganic materials under the polarised light microscope in order to interpret aspects of the provenance and technology of artefacts.

6. Microtome - Wikipedia

   en.wikipedia.org/wiki/Microtome

   For more detailed analysis of much smaller areas in a thin section, FTIR microscopy can be used for sample inspection. A recent development is the laser microtome, which cuts the target specimen with a femtosecond laser instead of a mechanical knife. This method is contact-free and does not require sample preparation techniques.

7. Ultramicrotomy - Wikipedia

   en.wikipedia.org/wiki/Ultramicrotomy

   Ultramicrotomy is a method for cutting specimens into extremely thin slices, called ultra-thin sections, that can be studied and documented at different magnifications in a transmission electron microscope (TEM). It is used mostly for biological specimens, but sections of plastics and soft metals can also be prepared.
