Ferromagnesian silicates, which include minerals like olivine and pyroxene, contain significant amounts of iron and magnesium. These elements contribute to the minerals' darker colors and higher densities due to their heavier atomic weights. The presence of iron also imparts magnetic properties, as iron is a ferromagnetic element. Consequently, the combination of these factors leads to the characteristic dark, dense, and often magnetic nature of ferromagnesian silicates.
What else can I help you with?
What characteristics do ferromagnesian minerals have in common?
Ferromagnesian minerals are rich in iron and magnesium, which give them dark colors like black, dark green, or brown. They are typically heavy, dense minerals with a high specific gravity. Additionally, ferromagnesian minerals often exhibit a distinct cleavage and are common in mafic igneous rocks like basalt and gabbro.
Which mineral is metallic silver very dense and an ore of lead?
The mineral you are referring to is galena. Galena is a dense, metallic mineral that is the primary ore of lead, composed of lead sulfide (PbS). It often appears in a crystalline form and is known for its high density and metallic luster.
Is lead a metallic element?
yes
Is O2 a metal or nonmetal?
Ozone is an allotrope of oxygen. It is a non-metal. Oxygen when compressed to very high pressures forms a dense metallic state. Presumably ozone can enter a similar metallic state at high pressures.
Why do you expect neutron stars to have a powerful magnetic field?
Neutron stars are expected to have strong magnetic fields because they are formed from the collapsed cores of massive stars, which inherently had strong magnetic fields. As the core collapses, conservation of magnetic flux leads to an intense magnetic field in the neutron star. Additionally, the rapid rotation of neutron stars can amplify their magnetic fields through processes like dynamo action.
What is the difference ferromagnesian and non-ferromagnesian silicates?
Ferromagnesian silicates contain iron and magnesium in their composition, which gives them a dark color and high density. Non-ferromagnesian silicates do not contain iron and magnesium, resulting in lighter colors and lower densities. Ferromagnesian silicates tend to be denser and have higher melting points compared to non-ferromagnesian silicates.
What characteristics do ferromagnesian minerals have in common?

What is a 4 letter word for a grey metallic element?
'Lead' is a dense, metallic element.
Is uranium non metallic or metallic?
Uranium is a natural chemical element, radioactive, dense, atomic number 92.Uranium is a solid metal.
What is densemetallic center of the Earth?
The dense metallic center of the Earth is known as the Earth's core. It is composed mainly of iron and nickel and is divided into a solid inner core and a liquid outer core. The core plays a crucial role in generating the Earth's magnetic field.
Why do scientists believethat the inner core is the source of earth's magnetic field?
The core is a dense chunck of metal that influence the earths magnetic field.
Why does hydrogen take on the properties of a metal in the planet Jupiter but not on the planet Earth?
Deep inside Jupiter hydrogen is in a very dense condition due to extreme pressure. This dense condition is called "metallic hydrogen" because then it can conduct electricity. On Earth the pressure is simply not strong enough to produce metallic hydrogen.
How does nickel feel?
Nickel is a hard, smooth, and dense metal. It has a cool sensation to the touch at room temperature.
What is Jupiter's structure like?
Jupiter is a gas giant, consisting mostly of hydrogen and helium. Its outer layers are composed of gas, while its interior likely consists of a small rocky core surrounded by a thick layer of metallic hydrogen. The intense pressure and temperature near the core create Jupiter's powerful magnetic field.
A magnetic material has a relative permeability of 10000 what does this mean?
The relative permeability of 10,000 means that the material can support a magnetic field 10,000 times more dense than than a magnetic field in free space.
Is lead a metallic element?
yes
Is O2 a metal or nonmetal?
Ozone is an allotrope of oxygen. It is a non-metal. Oxygen when compressed to very high pressures forms a dense metallic state. Presumably ozone can enter a similar metallic state at high pressures.
