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 islands have become highly noted for their flora and fauna, attracting ecotourists. One endemic, the Chatham Islands forget-me-not (Myosotidium hortensia), has become a botanical symbol of the islands due to its widespread cultivation in and outside New Zealand. [3] [2] The Chatham archipelago comprises 40 islands and rocks.
The East Aegean Islands is a biogeographic region that includes several islands and island groups in the eastern Aegean Sea, including Rhodes, Lesbos, Samos, Chios, Kos, Icaria, Symi, and many smaller islands. They are home to several dozen endemic species and subspecies of plants, including the endemic genus Kenopleurum. [1]
In 1986, California named benitoite as its state gemstone, a form of the mineral barium titanium silicate that is unique to the Golden State and only found in gem quality in San Benito County. [ 80 ] ^ Colorado is the only state whose geological symbols reflect the national flag's colors: red (rhodochrosite), white (yule marble), and blue ...
There are no plant species endemic to the islands; however, one variety of Pandanus tectorius, P. tectorius var. cocosensis, [1] is only found growing on these islands. The native vegetation of the two atolls primarily consists of sea-dispersed shoreline plants of the Indo-Pacific region.

[1] [2] However, most of the islands are covered by tropical forest. That is because the soil of volcanic origin is very fertile, and the climate is warm and humid. [ 3 ] Among the trees of these islands that stand out are the coconut tree , the breadfruit , the casuarina , the banana , the ceiba , the banyan , the ilang-ilang , the polynesian ...
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).
