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.
Altered samples of the Blue Ridge Ophiolite are green, with white and black crystals that are visible. In thin section some samples have no olivine such as the sample form Todd, North Carolina. Altered minerals that can be seen in thin section are chlorite and chromite. [3] Sample of Talc-Actinolite Schist taken from Todd, North Carolina ...
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 .
Psychology Today is an American media organization with a focus on psychology and human behavior. The publication began as a bimonthly magazine, which first appeared in 1967. The print magazine's reported circulation is 275,000 as of 2023. [ 2 ]
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.
He eventually left his post at the rehabilitation facility in 2011. “I was stuck in an abstinence model that didn’t work,” Kalfas said. Administrators of the facility “really need to be confronted with their success rates. In AA, the definition of insanity is doing the same thing over and over again and expecting a different result.
The spinels are any of a class of minerals of general formulation AB 2 X 4 which crystallise in the cubic (isometric) crystal system, with the X anions (typically chalcogens, like oxygen and sulfur) arranged in a cubic close-packed lattice and the cations A and B occupying some or all of the octahedral and tetrahedral sites in the lattice.
