The andesite rock contains some visible crystals of pyroxene or amphibole.

Pyroxene, ilmenite, magnetite, and olivine are the mafic minerals most commonly present.
From the en.wikipedia.org
For example, olivine and pyroxene, two primary minerals in basalt, form when lava solidifies.

- Any of a group of crystalline silicate mineral common in igneous and metamorphic rocks
- A common metasilicate, chiefly of calcium and magnesium, usually in short, thick, prismatic crystals; next to feldspar the most frequent constituent of igneous rocks
- A family of silicate minerals with a general formula Y2(Si,Al)2O6 where Y = Ca, Na, Mg, Fe, Mn). Pyroxenes occur in both igneous and metamorphic rocks. See also diopside.
- Pyroxene is a group of common rock-forming minerals. It is characterized by short, stout crystals and good prismatic cleavage in two directions intersecting at angles of about 87 degrees and 93 degrees. Source: Bates and Jackson (1984)
- One of a number of 5i04 silicate minerals common in meteorites
- Silicate mineral common in basic rocks containing varying amounts of Ca, Na, Mg and Fe.
- Most important group of rock-forming ferromagnesian silicates. Pyroxenes are divided into two groups: Orthorhombic orthopyroxenes (opx) and monoclinic clinopyroxenes (cpx). ...
- A common, dark-coloured, silicate mineral which contains iron and magnesium and is a common constituent of gabbro, anorthosite and some ultramafic rocks.
- One of the major groups of silicate (silicon and oxygen bearing) minerals.
