Type Occurrence of MaricopaiteHide

Type Locality:

ⓘ Moon Anchor Mine, Hummingbird Springs, Osborn Mining District, Maricopa County, Arizona, USA

General Appearance of Type Material:

Sprays of translucent white, acicular crystals. Thin bundles of extremely elongate acicular crystals, frequently as mats with admixed mimetite. Radial sprays up to 1.0 mm in diameter.

Place of Conservation of Type Material:

National Museum of Natural History (Smithsonian Institution), Washington, D.C., USA, numbers NMNH 163248 and 163247.

Geological Setting of Type Material:

Au-Pb-Ag mineralization in a vein deposit with pod-like ore bodies. Host rock is gneiss and schist. The type material came from the hanging wall of the vein which consists of calcite-fluorite gangue with many square voids thought to be from former galena.

Associated Minerals at Type Locality:
