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 ...
Itabirite, also called banded-quartz hematite or hematite schist, is a foliated, metamorphosed oxide-facies iron formation in which the original chert or jasper bands have been recrystallized into macroscopically distinguishable grains of quartz and the iron is present as thin layers of hematite, magnetite, or martite (pseudomorphs of hematite after magnetite).

Tests quickly found that the grey spherules are rich in grey hematite. [ 6 ] [ 7 ] [ 8 ] [ 26 ] [ 1 ] [ 9 ] These tests included doing the "berry bowl" experiment (more below). The moniker "blueberries" was coined for the grey hematite spherules by the original Opportunity science team due to these spherules appearing bluish relative to the ...
A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life.
Guillermo González Calderoni (26 March 1948 [1] – 5 February 2003) was a commander of the Mexican Federal Judicial Police, and one of the strongmen of the Attorney General of Mexico, who went on to accuse Raul Salinas de Gortari, the brother of former president Carlos Salinas de Gortari, of being involved in drug trafficking.
The structures are considered to be one of the oldest ecosystems on Earth, according to NASA, representing the earliest fossil evidence for life on our planet from at least 3½ billion years ago.
