Answer is basalt.
Basalt is fine grained igneous rock which contains 45 to 53% silica and 65% rich is feldspar in the form of plagioclase( silicate rock forming mineral). Feldspar is an abundant rock forming mineral. In basaltic rocks the feldspar is silica.
The basalt rocks contains pyroxene group in its minerals which gives it black color. So rocks containing many dark silicate minerals and plagioclase feldspar have basaltic composition.

Scientists are going to explore the ATMOSPHERE of Kepler-186f next. This is because there are still no known inventions that can analyze the atmospheric characteristics of this planet and conclude whether it is habitable or not. Its location is too far for our existing telescopes to fully analyze its atmosphere. Scientists are all on their toes to discover this planet's abilities for habitation by conceptualizing an instrument that could measure such.
