An igneous rock with distinct grains of mica, feldspar and quartz is?

The igneous rock with distinct grains of mica, feldspar, and quartz is granite. Granite is a coarse-grained igneous rock that is composed of minerals such as mica, feldspar, and quartz. Mica is a shiny mineral that forms in thin, flat sheets and gives granite a distinctive glittery appearance. Feldspar is a group of minerals that are the most common minerals in the Earth's crust, and quartz is a hard, crystalline mineral that is also very common in rocks. Granite is formed deep underground when magma cools slowly and crystallizes over time. The slow cooling allows the minerals to form distinct, visible grains, which is why granite has a coarse texture. The presence of mica, feldspar, and quartz in granite gives it a unique appearance and makes it a popular choice for building and construction, as well as for decorative purposes.
