Acidic water rich in iron then dissolve the calcite leaving behind the iron rich (hematite) spherule. This leads to the conclusion that the blueberries may have formed early in Mars's history when the atmosphere was more dense by the same process.
White beans. There’s a reason beans are a go-to for plant-based eaters. One half-cup of white beans offers nearly 3.5 mg of iron, the USDA says, along with 8.7 grams (g) of protein and 5.6 g of ...
Gongura comes in two varieties, green stemmed leaf and red stemmed. The red stemmed variety is sourer than the green stemmed variety. Gongura is a rich source of iron, vitamins, folic acid and anti-oxidants essential for human nutrition. [4]
Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al 2 Si 2 O 5 4), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water [1] and have been important to life, and many theories of abiogenesis ...
This mighty mineral courses through our veins, quite literally, playing a pivotal role in transporting oxygen and keeping our energy levels from dipping lower than our mid-day motivation at work ...
A popular, but apocryphal, story is that the town is named after "Princess Owatonna", the daughter of local Native American Chief Wabena who was supposedly healed by a nearby spring's magic waters, [7] which were said to be rich in iron and sulfur. [8] The earliest the Owatonna area was settled was in 1854.
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
Banded iron formation from the Barberton Greenstone Belt, South Africa. A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of iron-poor chert, often red in color, of similar thickness.
