Join us for a field trip to CK Williams Quarry, located along PA-611 on the far western end of the Franklin Marble formation. The marble here has been heavily altered to serpentine, with occurrences of asbestiform minerals and various micas.
Pegmatite bodies are also present and may contain minerals such as:
Feldspar
Quartz
Micas
Schorl (black tourmaline)
Titanite
Other associated minerals
Some radioactive minerals are present in the quarry, though they are typically disseminated and in trace amounts.
