Zinc Ore Willemite

  • Origin of the Ore Body — The Sterling Hill Mining Museum

    As the rocks descended, the heat and pressure increased, gradually changing (metamorphosing) the limestone into marble, and the metalrich layers into the zinc ore minerals (franklinite, willemite, zincite) we see today within the Franklin Marble at the Sterling Hill Mining Museum.

The model results show that willemite will precipitate in response to waterrock interaction and fluid mixing processes at temperatures above 120°C. The presence of arsenate in the hydrothermal fluid is
