1. Quartz: Quartz is a very hard and durable mineral that is resistant to weathering. It is a major component of granite and is often found as individual grains in soil.
2. Feldspar: Feldspar is another common mineral in granite. It is less resistant to weathering than quartz and tends to break down into clay minerals. These clay minerals are important components of soil, contributing to its structure and fertility.
While granite contains other minerals like mica and hornblende, they are often less abundant in soils compared to quartz and feldspar.
