Hematite (/ ˈ h iː m ə ˌ t aɪ t, ˈ h ɛ m ə-/), also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. [6] Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3. It has the same crystal structure as corundum ...
The Treatise on the Reintegration of Beings into Their Original Estate, Virtues and Powers both Spiritual and Divine (French: Traité de la Réintégration des êtres dans leurs premières propriétés, vertus et puissance spirituelles et divines) is a book written in 1772-73 by Martinès de Pasqually.

[5] Mirrors were viewed as metaphors for sacred caves and as conduits for supernatural forces; they were associated with fiery hearths and pools of water because of their bright surfaces.
Mineral symbols (text abbreviations) are used to abbreviate mineral groups, subgroups, and species, just as lettered symbols are used for the chemical elements. The first set of commonly used mineral symbols was published in 1983 and covered the common rock-forming minerals using 192 two- or three-lettered symbols. [ 1 ]
Magnetite has been important in understanding the conditions under which rocks form. Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control how oxidizing its environment is (the oxygen fugacity). This buffer is known as the hematite-magnetite or HM buffer.
along with symbols for upperclass point guards, high scoring big men, team scoring averages and point differentials. Teams with the most symbols have the best chances at making deep runs. Keep in mind that very few teams have won it all with young point guards and/or low scoring post players. Be considerate of free throw percentages as teams
Martian spherules (also known as hematite spherules, blueberries, & Martian blueberries) are small spherules (roughly spherical pebbles) that are rich in an iron oxide (grey hematite, α-Fe 2 O 3) and are found at Meridiani Planum (a large plain on Mars) in exceedingly large numbers.
Whether you call it the clenched fist, Black Power fist, BLM fist, or solidarity fist, one thing is clear: it’s used as a symbol of Black pride, solidarity, and dedication to fighting injustice.
