Detailed Mineral List:
Albite
Habit: short, feathery aggregates lining rare pockets, otherwise massive
Colour: white to cream
Description: Stugard (1958) sampled and analyzed many pegmatites in the district (though not this one) and found the plagioclase to have only 3 to 7 percent anorthite. Rare pockets are lined with subparallel, chisel-tipped (feathery) crystal aggregates.
Reference: Stugard, Frederick, Jr. (1958). Pegmatites of the Middletown Area Connecticut. USGS Bulletin 1042-Q.; Cameron, Eugene N., David M. Larrabee, Andrew H. McNair, James T. Page, Glenn W. Stewart, and Vincent E. Shainin. (1954): Pegmatite Investigations 1942-45 New England. USGS Professional Paper 255.; Harold Moritz collection.

Almandine
Habit: trapezohedral
Colour: red-brown
Description: XRF analyses by Harold Moritz indicate almandine with a spessartine component, which is typical of garnets in the district's pegmatites.
Reference: Weber, Marcelle H. and Earle C. Sullivan. (1995): Connecticut Mineral Locality Index. Rocks & Minerals (Connecticut Issue): 70(6): 403.; Harold Moritz collection.

Annite
Habit: elongated subhedral tabular
Colour: black
Description: fka biotite, Long (up to several dm) tabular crystals are abundant in the graphic granite zone, which makes up most of the dump material and is barren of other minerals. Groups of a few crystals typically radiate from a point.
Reference: Harold Moritz collection

Beryl
Habit: generally stubby to elongated hexagonal prisms, poorly terminated, except in pockets (rare).
Colour: aqua, pale green, yellow
Description: Beryl occurs as mostly subhedral matrix crystals 1 to 8 inches in length and 1/2 to 5 inches in diameter. But euhedral, gemmy aquamarines rarely occur in pockets.

Columbite-(Fe)
Habit: elongated prisms to anhedral grains
Colour: black with iridescence
Description: Mostly small crystals <1 cm in albite, could be more common but hard to detect with the abundance annite and schorl.

'Feldspar Group'
Description: see details under "microcline"
Reference: Cameron, Eugene N., David M. Larrabee, Andrew H. McNair, James T. Page, Glenn W. Stewart, and Vincent E. Shainin. (1954): Pegmatite Investigations 1942-45 New England. USGS Professional Paper 255.
'Feldspar Group var: Perthite'
Description: see details under "microcline"

Hematite
Reference: P. Cristofono collection, 2013
Microcline
Habit: elongated prisms rare from pockets, otherwise large equant crystals in quartz core pods and cleavable masses
Colour: white to cream
Description: Stugard (1958) sampled and analyzed many pegmatites in the district (though not this one) and reports that the pethite in the district is microcline hosting albite. Large equant crystals 50-60 cm exposed along the boundaries of quartz core "pods". Crystals to several cm rarely found in pockets and these are typically etched.

Muscovite
Habit: tabular, mostly subhedral
Colour: silver to rum
Description: Besides subhedral material in the pegmatite matrix, mostly found around the edges of quartz core "pods" where they can be subhedral and up to 7-8 cm and 1-2 cm thick, rarely found as euhedral, thicker books in pockets.
Reference: P Cristofono collection, 2007; Cameron, Eugene N., David M. Larrabee, Andrew H. McNair, James T. Page, Glenn W. Stewart, and Vincent E. Shainin. (1954): Pegmatite Investigations 1942-45 New England. USGS Professional Paper 255.

Quartz
Colour: clear, white, smoky
Description: Mostly massive as part of the pegmatite matrix. Excellent crystals to several cm are rarely found in pockets.
Reference: P Cristofono collection, 2007; Cameron, Eugene N., David M. Larrabee, Andrew H. McNair, James T. Page, Glenn W. Stewart, and Vincent E. Shainin. (1954): Pegmatite Investigations 1942-45 New England. USGS Professional Paper 255.; David Busha collection

Colour: pale rose
Description: Massive material very rare.
Reference: David Hanson collection
Quartz var: Smoky Quartz
Habit: trigonal pocket crystals rare, mostly massive
Colour: smoky
Description: Abundant as massive pegmatite matrix component. Crystals rarely found in pockets can be several cm long.

Schorl
Habit: stubby to elongated prisms, mostly subhedral in matrix
Colour: black
Description: Poor crystals to 15-20 cm in matrix. The best crystals to several cm occur in the pocket zone.

Spessartine ?
Description: Listed based upon speculation, XRF analyses of pegmatitic garnets show mostly impure almandine.
