* Clay minerals: Granite contains feldspar, which is chemically weathered to form clay minerals like kaolinite, illite, and smectite.
* Iron oxides: Iron-containing minerals in granite can be oxidized, leading to the formation of iron oxides like hematite (red) and goethite (yellow-brown).
* Dissolved ions: Chemical weathering can dissolve minerals in granite, releasing ions like calcium, sodium, potassium, and silica into solution.
* Quartz: Quartz, a very resistant mineral, is often left behind as a residue from chemical weathering of granite.
* Silt and sand: These particles are produced as the granite breaks down into smaller pieces.
Therefore, the product of chemical weathering of granite is a mixture of clay minerals, iron oxides, dissolved ions, quartz, and silt/sand. The specific composition of this mixture depends on the specific weathering processes, the original composition of the granite, and the climate conditions.
