Berlin is a town that was incorporated in 1785. The geographic center of Connecticut is located in the town, and the town is a mix of residential and industrial.

It is underlain by heavily faulted Jurassic sedimentary (Shuttle Meadow and East Berlin formations) and basaltic rocks (Talcott, Holyoke and Hampden formations). Many of the faults are mineralized with calcite, quartz, dolomite, barite and copper sulfides. Vesicles in the basalts also can contain calcite, prehnite and zeolites. The East Berlin formation, which contains several lakebed sequences, including fossiliferous and petroleum rich black shales, is named for the village in the eastern part of the town, where it is well exposed in road cuts along state Routes 9, 15, and 372, especially where all three intersect. Dinosaur footprints are common in the mudstones and sandstones.

Detailed Mineral List:

Aragonite
Formula: CaCO3
References:
Fred Schuster collectionIdentification: Visual Identification
Baryte
Formula: BaSO4
Habit: slightly divergent tabular coxcomb aggregates
Colour: pearly white
Description: In slightly divergent "coxcomb" aggregates that are brittle and tend to break into slightly rhombic fragments. Very difficult to detach it in large masses.
Calcite
Formula: CaCO3
Habit: foliated, granular, and fibrous
Colour: colorless
Description: "colourless and crystallized, or foliated; agatized, i.e. in layers of different colours and textures, foliated, granular, and fibrous. The fibrous layers are generally external, thin, with the fibres perpendicular to the direction of the layers." Percival, 1822.
Dolomite
Formula: CaMg(CO3)2
Habit: rhombohedral
Colour: white
Description: curved rhombohedral crystals in hydrothermal fault veins with other minerals.
Fluorite
Formula: CaF2
Habit: cubic
Colour: aqua and purple
Fluorescence: violet
Description: Partly filling small vugs in a 2-cm-thick vein of dolomite.
Galena
Formula: PbS
Habit: cubic
Description: "small cubical crystals, foliated, and finely granular; the crystals which are exposed to the air are often covered with a thin pulverulent coat, or they are beautifully iridescent." Percival, 1822.
Goethite
Formula: Fe3+O(OH)
Habit: acicular
Colour: brown
Description: Aggregates of microcrystals.

Harold Moritz CollectionIdentified by Harold Moritz: Visual Identification
Hematite
Formula: Fe2O3
Colour: maroon
Description: Tiny blebs on other minerals.

Harold Moritz CollectionIdentified by Harold Moritz: Visual Identification
'Petroleum var. Bitumen'
Colour: black
Description: "...found in veins in connection with crystallized quartz; the quartz often appears in geodes whose cavities are filled with coal [bitumen]; narrow veins have their walls lined with crystallized plates of quartz, and are filled with coal [bitumen]; the coal [bitumen] has never been found in large masses: the largest that I have seen not more than two or three pounds. The larger masses are foliated, shining, brittle, and very bituminous; but it more usually has the appearance of cinders so mixed up with silicious matter as to be hardly combustible." Percival, 1822.
Prehnite
Formula: Ca2Al2Si3O10(OH)2
'Pumpellyite Subgroup'
Formula: Ca2XAl2[Si2O6(OH)][SiO4](OH)2A
Colour: green
Description: Originally believed to be fine-grained chlorite. In gas vesicles in basalt.
Pyrite
Formula: FeS2
Quartz
Formula: SiO2
Habit: lining geodes, in parallel-growth plates, prismatic
Description: In geodes and crystallized plates, loose in the stream - some nearly perfect, one an inch long, with the prism and two pyramids, and some slightly tinged with amethyst.
Quartz var. Agate
Formula: SiO2
Colour: blue and white
Description: In gas vesicles in basalt.
Quartz var. Amethyst
Formula: SiO2
Quartz var. Chalcedony
Formula: SiO2
Description: In gas vesicles in basalt.
Sphalerite
Formula: ZnS
Habit: massive
Colour: yellow and black
Description: "it is in much larger masses than the galena" Percival, 1822.
