How Do You Spell EDENHARTERITE?

Pronunciation: [ˈɛdənhˌɑːtəɹˌa͡ɪt] (IPA)

Edenharterite is a mineral that was discovered in 1975. The word is spelled "ed-en-hart-er-ite" and is pronounced /ˌɛdənˈhɑːrtəraɪt/. The first part of the word "eden" is pronounced with a short "e" sound, followed by "hart" which is pronounced with a long "a" sound. The second part of the word "erite" is pronounced with a short "i" sound followed by "t". This rare mineral is found in metamorphosed limestone and is named after John W. Edenharter, a mineralogist who had contributed significantly to the study of ore deposits.

EDENHARTERITE Meaning and Definition

1. Edenharterite is a mineral compound that belongs to the group of copper sulfosalts. It was first discovered in the early 20th century and was named after its type locality, which is the Edenharter mine in the region of Styria, Austria. This mineral occurs as a rare secondary formation, often found in the oxidized zone of copper-bearing deposits.

   The chemical formula of edenharterite is generally described as PbCu3Bi7(S,Se)12, indicating the presence of lead (Pb), copper (Cu), bismuth (Bi), sulfur (S), and selenium (Se) in its composition. It belongs to the orthorhombic crystal system and commonly exhibits prismatic or tabular crystals with a black or dark gray color.

   Edenharterite is known for its high density and resistance to oxidation. It has a metallic luster and a non-metallic to deep black streak. Under polarized light, it may display various pleochroic colors, ranging from light yellow to brownish-yellow. This mineral is typically brittle and has a conchoidal fracture pattern.

   Due to its scarcity and specific occurrence in certain geological conditions, edenharterite is considered a rare mineral. Its exact crystal structure and physical properties are still being studied to provide a more comprehensive understanding of its characteristics.
