Detailed Mineral List:

Aegirine
Formula: NaFe3+Si2O6
Localities: Reported from at least 18 localities in this region.
Aenigmatite
Formula: Na4[Fe2+10Ti2]O4[Si12O36]

Localities: Reported from at least 8 localities in this region.
Reference: Gleba, 1978. Mass. Mineral & Fossil Localities
Albite var: Oligoclase-Albite

'Allanite Group'
Formula: {A12+REE3+}{M3+2M32+}(Si2O7)(SiO4)O(OH)
Reference: Dale, T.N. (1908) The Chief Commercial Granites of Massachusetts, New Hampshire and Rhode Island. United States Geological Survey, Bulletin 354, 228 pages.
Anatase
Formula: TiO2
'Apatite'
Reference: Dale, T.N. (1908) The Chief Commercial Granites of Massachusetts, New Hampshire and Rhode Island. United States Geological Survey, Bulletin 354, 228 pages.
Arfvedsonite
Formula: [Na][Na2][Fe2+4Fe3+]Si8O22(OH)2
Description: The presence of such a sodic amphibole in this rock is unverified. No chemical analysis in the reference cited. Optical evidence would be insufficient to establish the validity of this report, although no optical data are given in support. Chemical analyses from as early as Warren and Palache (1916) through Lyons (1976) definitely and unambiguously show good chemical analyses for riebeckite and insufficient soda to significantly approach the afrvedsonite boundary.

Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Pennsylvanian
298.9 - 323.2 Ma



ID: 3184341
Paleozoic sedimentary rocks

Age: Pennsylvanian (298.9 - 323.2 Ma)

Comments: Narragansett And Boston Basins

Lithology: Sedimentary rocks

Middle Cambrian - Early Cambrian
501 - 541 Ma



ID: 2771206
Braintree Argillite and Weymouth Formation

Age: Cambrian (501 - 541 Ma)

Stratigraphic Name: Braintree Argillite

Description: Argillite, some with rare limestone; contains Middle and Early Cambrian faunae respectively.

Comments: Part of Milford-Dedham Zone (Tertiary and Older Rocks). Secondary unit description per MA023 as reported in USGS Geologic Names lexicon (ref. MA024): Braintree Argillite is present only south of Boston basin in and around Quincy Granite. Consists of noncalcareous green to dark-gray or black massive slate or argillite. Adjacent to Quincy Granite, it is indistinctly bedded greenish-gray hornfels. Thickness estimated at 1000 m (LaForge, 1932). Contact with underlying Weymouth Formation not exposed; top of formation not known. No measured section has been done by any worker. Faunal assemblage is characterized by Middle Cambrian representatives of PARADOXIDES (trilobite) (Goldsmith, 1991). Weymouth Formation consists of greenish-gray and dark-red slate containing calcareous nodules, and subordinate beds and lenses of argillaceous limestone. Locally converted to hornfels by intrusion of Quincy Granite. At Nahant, MA, contains layer of greenish-white limestone. Lithology is similar to Hoppin Formation at Hoppin Hill, MA, except that lower quartzitic part of section has not been recognized in the Weymouth. No complete section of Weymouth has been described by any worker. Base is not exposed and can only be inferred to be at least 100 m thick (LaForge, 1932). Fossils in Weymouth are largely conoidal forms, but include some olenellids. Age is Early Cambrian (Goldsmith, 1991). Original map source: Unpublished Digital Geologic Map of Massachusetts received from Rudi Hon of Boston College in 1998; based on the 1983 USGS paper version (MA002).
