Fluorite was identified based on a cubic crystal structure and a rich purple color, Pyrite was identified based on a metallic luster, a black streak and a cubic crystal structure, Molybdenite was determined based on a lead blue color metallic luster and a platy habit. All were found in the Gardner Quarry, and all were in settings which are consistent with the identification, mineralization in granitic rocks.

	Chlorite was found in a small aggregat together with muscovite (illite) and calcite. Identified at NHM, Oslo.
	2 Wollastonite specimens found in a mine run flat which was part of Steve Pullman's collection. A business card from William J. Keith, geologist with USGS, Menlo Park, on the back of which, a list of species in the flat indicating the specimens were collected during April, 1996.
	A piece of blueschist matrix often called "Crossite" was personally collected and analyzed by David Lowe. It contained Ferri-Winchite matching reference XRD pattern PDF 00-052-1577 and Albite PDF 01-084-0752. It was in direct contact with Neptunite, which was separately found to match PDF 00-043-0677. No other crystalline phases were found.
