Hydrozincite
Zinc Carbonate Hydroxide
Zn5(CO3)2(OH)6.

Hydrozincite forms in the oxidation zones of zinc deposits as masses or crusts.  Crystals are rare.  Hydrozincite may be present on some specimens but goes unnoticed.  Assumed to be some other more common mineral, such as calcite or aragonite.

Willemite
Zinc Silicate
Zn2Sio4.

Willemite is a rare zinc mineral.  The deposit at Franklin, New Jersey is unique.  Minerals such as Zincite, Franklinite, Rhodonite, Greenockite, fluorescent Calcite and various zeolites.  In the case of Willemite the secondary minerals were probably Smithsonite and Hemimorphite.  At other localities for Willemite it is more scarce and forms as a secondary mineral from primary zinc deposits.

Renamed in 1830 in honor of William I, King 1813-1840 of the Netherlands.

Franklinite
Zinc Iron Manganese Oxide
Zn2+Fe23+O4.

It forms octahedral crystals that are typical of the Spinel group of minerals.  Specimens from Franklin often contain the rounded black grains of Franklinite surrounded by white Calcite.   Some have greenish Willemite with a sprinkling of red Zincite.

Calcium Carbonate
CaCO3.

Calcite name is from chalix the Greek word for lime.  This is a most amazing yet, common mineral.  Comprising about 4% by weight of the Earth’s crust and formed in many different geological environments.  Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types.  It forms oolitic, fossiliferous and massive limestones in sedimentary environments.  Calcite serves as the cements for many sandstones and shales.  Limestone becomes marble from the heat and pressure of metamorphic events.  Calcite forms the major portion of many hydrothermal veins.

More Info

Calcite is so abundant and widely distributed it is no wonder that it can be so varied.  The crystals of calcite can form literally a thousand different shapes.  By combining basic forms of the rhombohedron, various scalahedrons, prism and pinacoid to name a few.  There are more than 300 Calcite crystal forms identified, combined to produce a thousand different crystal variations.  Calcite also produces many twin varieties, they are favorites among twin collectors.  There are also phantoms, included crystals, colour varieties, pseudomorphs and unique associations.  Fluorescent Calcites often contain Lead and Manganese.
