Wilton is a town incorporated in 1802. Before that, it was a parish first recognized in 1726 and was part of Norwalk.

Geologically, Wilton lies within the Connecticut Valley Terrane of metamorphic rocks. The north central part of town is underlain by members of the Ordovician Harrison Gneiss metadiorite. A small body of ultramafic rock crops out at the southern end of these metaplutons, just north of the town center. A belt of Ordovician Rowe Schist lies to the east of the Harrison Gneiss (along northern US Route 7 and under Honey Hill), Both these rock units are surrounded by Ordovician unnamed felsic orthogneiss, which at the southern end of town is mixed with the Ordovician Trap Falls Formation.

Detailed Mineral List:

Albite
Formula: Na(AlSi3O8)
Almandine
Formula: Fe2+3Al2(SiO4)3
Habit: dodecahedral
Colour: maroon
Description: Large (>5 cm) somewhat rounded crystals. XRF analysis by Harold Moritz of his crystals yielded Fe:Mn ratio of 99:1, making it very pure almandine.
Arsenopyrite
Formula: FeAsS
'Asbestos'
Chalcopyrite
Formula: CuFeS2
Galena
Formula: PbS
'Garnet Group'
Formula: X3Z2(SiO4)3
Microcline
Formula: K(AlSi3O8)
Muscovite
Formula: KAl2(AlSi3O10)(OH)2
Pyrite
Formula: FeS2
Quartz
Formula: SiO2
Schorl
Formula: NaFe2+3Al6(Si6O18)(BO3)3(OH)3(OH)
Colour: black
Description: Hiller (1967) says they are about 1 inch long and "extremely well formed", but hard to find and remove from the feldspar.
Sphalerite
Formula: ZnS
Talc
Formula: Mg3Si4O10(OH)2
