Mafic magma and rock are higher in density that felsic magma and rock.
No, quartz is not mafic. Mafic minerals are rich in magnesium and iron, while quartz is a silicate mineral composed of silicon and oxygen. Quartz is classified as a felsic mineral due to its composition and low mafic content.
Mafic is a term used to describe an igneous rock that is usually dark in color, with a chemistry that may be high in magnesium and iron, like basalt. Mafic is also a term used to describe a type of magma that is high in calcium, magnesium and iron, and relatively low in silica, compared to felsic magma.
Silica content increases from mafic to felsic, and Mg and Fe content decreases. These differences affect things such as viscosity, density and colour. Felsic magmas are the most viscous and least dense, and felsic rocks are the lightest in colour.
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.
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.

Mafic magma has low silica content. It is usually rich in magnesium and iron, leading to its high density and fluid-like behavior. Mafic magmas tend to form basaltic rocks when they solidify.
This type of magma is called mafic magma. It has a low viscosity due to its low silica content, allowing gases to escape easily. It typically contains high levels of iron and magnesium, making it darker in color.

To help with low bone mineral density you should start by drinking more milk, and getting a calcium pill.

Charcoal has a low density because it is porous and lightweight.

Quite low density: 0.968 g·cm−3
Peridotite is ultramafic, composed predominantly of mafic minerals such as olivine and pyroxene. It has low silica content and high magnesium and iron content, making it different from felsic, intermediate, and mafic rocks.
