The Chickies Quartzite is primarily composed of quartz, with minor amounts of other minerals like:

* Feldspar: Mostly potassium feldspar (orthoclase) and some plagioclase feldspar.

* Micas: Muscovite and biotite.

* Garnet: Almandine and pyrope garnets are sometimes present.

* Iron oxides: Hematite and goethite, giving the rock its characteristic reddish color.

* Accessory minerals: Zircon, tourmaline, and apatite may also occur in small amounts.

The high quartz content gives the Chickies Quartzite its characteristic hardness and resistance to weathering.
