Chromite can also be presented in a thin section. The grains seen in thin sections are disseminated with crystals that are euhedral to subhedral. [12] Chromite contains Mg, ferrous iron [Fe(II)], Al and trace amounts of Ti. [5] Chromite can change into different minerals based on the amounts of each element in the mineral.
Additionally, people with thin boundaries appeared to value their dreams more, especially in terms of their meaningfulness and creative aspects. A finding that people with thin boundaries were more likely to report having had childhood nightmares led the authors to suggest that boundary thinness may be relatively stable across the lifespan.
The following tests are some examples of those that are used on hand specimens, or on field samples, or on thin sections with the aid of a polarizing microscope. Color; Color of the mineral. Color alone is not diagnostic. For example quartz can be almost any color, depending on minor impurities and microstructure. Streak
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
Thin slice may refer to: Thin-slicing, a term used in psychology and philosophy to describe the ability to find patterns in events based only on "thin slices," or narrow windows, of experience. Thin slice, a presentation form for CT scans. In geology, a thin section
Thin-slicing is a term used in psychology and philosophy to describe the ability to find patterns in events based only on "thin slices", or narrow windows, of experience. The term refers to the process of making very quick inferences about the state, characteristics or details of an individual or situation with minimal amounts of information.
At higher temperatures, it will be altered to iron-rich chromite (ferrit-chromite). [28] During serpentinization, the rock is enriched in chlorine , boron , fluorine , and sulfur. Sulfur will be reduced to hydrogen sulfide and sulfide minerals, though significant quantities are incorporated into serpentine minerals, and some may later be ...
In such cases, a thin section of the mineral is used and examined under polarized transmitted light with a petrographic microscope. Another device using this property to identify minerals is the dichroscope .
