This mineral is olivine: (Mg, Fe)2SiO4.
First of all there is no such thing as a mafic or a felsic "mineral". There can be mafic and felsic rocks.Mafic rocks have a high magnesium and iron content.Felsic rocks enriched with lighter elements such as oxygen and silicon.
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
Dark, mafic rock is relatively rich in iron and magnesium.
The mineral Olivine is a series between two end members, fayalite and forsterite. Fayalite is the iron rich member while forsterite is the magnesium rich member.
Mafic and ultramafic minerals, high in magnesium and iron.

magnesium. we have iron in our hemoglobin, and plants have a similar shaped molecule with magnesium in the same location, called chlorophyll
An anthophyllite is a dark brown amphibole mineral, a mixed silicate of iron and magnesium.
Magnesium
Dark, mafic rock is relatively rich in iron and magnesium.
Mafic is a silicate mineral or rock that is rich in magnesium and iron, and is usually dark in color. It is formed from cooling volcanic lava.
