Igneous rocks with high iron and magnesium content are known as mafic. This word comes from the combination of the "Ma" for magnesium and Fe for iron, MaFe, Mafic

A high concentration of a mineral in rock?

Rocks usually get different concentration levels as different strata are reached. The silica and magnesium content in rocks increases as the depth increases.


Are basaltic igneous rocks high in iron and magnesium?

Yes, basaltic igneous rocks are typically high in iron and magnesium. This is because basalt forms from the partial melting of the Earth's mantle, which is rich in these elements. The high iron and magnesium content gives basalt its dark color and dense, fine-grained texture.


What property is common to most dark colored igneous rocks?

Most dark-colored igneous rocks have a high density.


Igneous rocks that are dense and dark colored they form from magma that is rich in iron and magnesium and poor in silica?

These types of igneous rocks are commonly known as mafic rocks. They have a high density due to the presence of minerals like olivine, pyroxene, and amphibole, which are rich in iron and magnesium. Examples include basalt and gabbro.


Dark colored igneous rock rich in iron and magnesium?

Dark, mafic rock is relatively rich in iron and magnesium.


What are mafic rocks?

A mafic rock is composed of mafic minerals such as biotite mica, amphibole, proxene, and olivine. The actual word mafic refers to magnesium and iron; nevertheless, these minerals are called ferromagnesian. Mafic rocks include gabbro, scoria, and basalt. They each have about 46-85% mafic mineral crystals. Periodite, 86-100% mafic minerals, is considered ultramafic because of its olivine composition.


What does hardwater contain?

Hard water contains high levels of minerals such as calcium and magnesium. These minerals can cause mineral deposits to form in plumbing and appliances, as well as leave spots on dishes and glassware after washing.


Igneous rocks like gabbro and basalt are silica-deficient with high magnesium and iron?

Yes, this is true. The rocks in question are 'Mafic' or 'Basic'. Mafic minerals are often dark in colour, and are indeed composed of Iron, with a good portion of Magnesium and other elements. They are Silica/Quartz deficient, and also note that the mineralogy makes Basaltic lava particularly runny, as opposed to Andesitic lava, with high Silica, which is very viscous.


What are some foods high in magnesium, and how does the magnesium content in bananas compare to other sources?

Foods high in magnesium include nuts, seeds, leafy greens, and whole grains. Bananas also contain magnesium, but they have lower levels compared to sources like almonds and spinach.


Why are mafic minerals dark in color?

Mafic minerals are dark in color because they contain high levels of iron and magnesium, which are elements that produce dark hues. The presence of these elements in the mineral's chemical composition gives it a darker color compared to minerals with lower iron and magnesium content.


What salt is produced from phosrpoic acid and magnesium hydroxide?

Magnesium phosphate is the salt produced from the reaction between phosphoric acid and magnesium hydroxide. It is commonly used in fertilizers and food supplements due to its high levels of magnesium and phosphorus.


What minerals have a cardiotoxic effect when their levels are to high or to low?

Potential culprits include potassium, magnesium, and calcium. High levels of potassium or calcium can affect the heart's electrical activity, potentially leading to arrhythmias, while low levels of magnesium can also disrupt heart rhythm and function. Monitoring these mineral levels is crucial for maintaining heart health.
