Granite pegmatite. Oxford Field. The Berry Quarry (south side) and Havey Quarry (north side) are in the same pegmatite and excavations have overlapped. The name of the united excavation is the Berry-Havey Quarry. The southern part of the pegmatite was operated by Forrest Havey, at least by 1909, while the northern portion was operated by A. R. Berry, beginning in 1900, who owned the farm.
This locality is the "type" location for the variety "watermelon tourmaline" and that name first appeared in print by George Howe in August, 1910. The name first received international circulation in 1911.
As of 2014 was being operated commercially by Jeff Morrison for gemstone and mineral specimen production.

|Silurian Sangerville Formation, Patch Mountain member|
Age: Silurian (427.4 - 443.8 Ma)
Stratigraphic Name: Patch Mountain Member
Description: Silurian Sangerville Formation Patch Mountain member
Comments: In central Maine trough, Sangerville Formation is mapped as principal sandstone and shale facies, and subdivided into (ascending) Patch Mountain Limestone Member (name revised from Patch Mountain Member to emphasize lithology), consisting of thinly interbedded impure marble, coarsely crystallized calc-silicate rocks, granofels, and pelitic schist (high metamorphic grade), or thinly interbedded, gray micritic metalimestone, limy metasandstone, metasiltstone, and slate or pelitic schist (low metamorphic grade); a conglomerate member; euxinic shale lenses; Taylor Pond Member of Hussey (1983), consisting of feldspathic biotite- and hornblende-biotite granofels, thinly bedded calc-silicate rocks, and sparse garnet-rich laminations (coticule); an unnamed limestone member similar to Patch Mountain Limestone Member but at a higher stratigraphic level; and Thorncrag Hill Member of Hussey (1983), consisting of migmatitic pelitic gneiss and some calc-silicate rocks. Anasagunticook Member of Pankiwskyj and others (1976) and Moench and Pankiwskyj (1988) is tentatively reassigned to Waterville Formation, following usage of Osberg (1988). (ME004) Unit description from USGS GEOLEX website (ME078). AA - Low rank amphibolite facies; AB - Medium rank amphibolite facies; AC - High rank amphibolite facies; GS - Greenschist facies; E - Epidote-amphibolite facies; Protolith R - Interbedded pelite and limestone and/or dolostone.
