- Pink granite is a coarse igneous rock with crystalline texture1. It is pink-reddish due to the alkali feldspar, which is one of the most abundant rock-forming minerals of the continental crust23. It also contains white quartz, grey plagioclase, and black biotite or hornblende21. To identify pink granite, you need to look at the color, shape, and fracture of the minerals45.Learn more:✕This summary was generated using AI based on multiple online sources.
