| ⓘ Formula: (Ca,Y,Ce)F2+x Locality: Bolton Lime Quarries (Bolton Quarry; Whitcomb Quarry; Hildreth Quarry), Bolton, Worcester County, Massachusetts, USA - erroneously reported Description: Properly identified yttrocerite contains some yttria. However, a common practice in the nineteenth century was to call all dark purple fluorite by the name "yttrocerite". No chemical analyses of this mineral are known from Bolton and it is uncertain if it were found in the marble or in pegmatite float boulders and the name seems to be incorrectly used. |
| ⓘ Forsterite Formula: Mg2(SiO4) Localities: Description: Boltonite was once thought to be a new mineral but it was later proven to be forsterite. Hitchock (1835), p.309: "At Bolton, also, a new mineral has been discovered, which Dr. Thomson has denominated from its chemical composition, Bilsilicate of Magnesia; and Mr. Shephard, with reference to its locality, calls it Boltonite. It occurs in foliated masses in the limestone." |
| ⓘ 'Gadolinite' ? Localities: Description: Gadolinite is a mineral characteristic of rare-earth rich granite pegmatites or alpine veins. No data have been published on the identification and efforts to locate any example, verified or not have been fruitless. The mineral may have been found in erratic pegmatite boulders, but certainly not in the marble. |

| ⓘ Pargasite Formula: NaCa2(Mg4Al)(Si6Al2)O22(OH)2 |
| ⓘ Petalite Formula: LiAl(Si4O10) Localities: Fluorescence: blue Description: Palache (1923) says that it is probable that the petalite reported by Dana was found in an erratic boulder, and not the quarry proper.
