Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?
Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.
What minerals found in rocks can attract materials containing iron?
Magnetite (lodestone) is the most magnetic of all the naturally occurring minerals on Earth and will attract small pieces of iron.
What minerals are found in mafic rocks?

Can vitamins be found in rocks or soil?
Rocks and soil usually contain elements such as minerals, nutrients like iron and boitin metallics elements as such only.
Where can iron be found?
Iron can be found in a variety of sources such as iron ores, which are rocks and minerals from which metallic iron can be extracted; in the Earth's crust; and in a variety of food sources such as red meat, poultry, seafood, lentils, and fortified cereals.
Does an igneous rock contain iron?
Igneous rocks can contain iron, but not all igneous rocks do. The presence of iron in an igneous rock depends on the composition of the magma from which the rock formed. Iron can be found in minerals such as magnetite, hematite, and pyroxene within certain igneous rocks.
What minerals is iron found in?
Iron IS a mineral.
