Adamite


Adamite is a zinc arsenate. Friedel (1866) named the species after Gilbert-Joseph Adam (1795-1881), French mineralogist and mineral collector, who discovered the mineral on Chilean specimens. The first report of Ojuela adamite appears in the 1923 Catálogo sistemático de especies minerales de México published in Mexico City. American mineralogists and collectors remained unaware of the occurrence until 1946, when American collectors Dan Mayers and Francis Wise happened upon abundant well-crystallized adamite (Mrose et al., 1948). The adamite find of 1946 was world-class; top specimens were placed on display at Harvard University and the Smithsonian. A succession of mineral buyers subsequently journeyed to Ojuela with sufficient regularity to establish a local specimen mining industry, which continues to this day.

Adamite specimens of this type came out in the late 1960s and early 1970s. Adamite forms radiating fans, also known as pinwheels, to 1.4 across. The gossan matrix here is nearly covered by glistening fluorescent yellow adamite. There is some damage along the long edge of the specimen. Attractive. A dealer label from Friedrich Schweiger of Vienna, Austria accompanies the specimen.
