franklinite

Franklinite is a mineral first described at Sterling Hill Mine.

Found in association with calcite, franklinite, willemite, hardystonite and clinohedrite.

Mr. Koskovich called himself a "Franklinite," his word for a lifelong resident.

The mineral association (assemblage) from Franklin includes willemite, zincite and franklinite.

It always occurs with flinkite, franklinite, andradite and cahnite.

Franklinite and zincite are not fluorescent.

Franklinite is a mineral with formula ZnFeO.

Other minerals often associated with hardystonite are franklinite, diopside, andradite garnet, and esperite (fluoresces yellow).

Sonolite has been found in association with calcite, chlorite, franklinite, galaxite, manganosite, pyrochroite, rhodochrosite, tephroite, willemite, and zincite.

It occurs in association with: zincite, willemite, franklinite, rhodonite, jacobsite, diopside, gageite, bustamite, manganocalcite, glaucochroite, calcite, banalsite and alleghanyite.

Fowlerite occurs as large, rough crystals, somewhat resembling pink feldspar, with franklinite and zinc ores in granular limestone at Franklin Furnace in New Jersey.

Increased interest in the franklinite and iron and zinc ores from Franklin further northeast of Newton prompted the New Jersey Legislature to adopt another supplement on February 4, 1863, that authorized the railroad to continue its line up to the Franklin Furnace and to other points north if "deemed most for the public good."
