ARGENTOTENNANTITE Meaning and
Definition
-
Argentotennantite is a mineral compound that belongs to the tennantite group. It is an uncommon sulfosalt mineral that is composed of the elements copper, silver, arsenic, and sulfur. The name "argentotennantite" is derived from its composition - "argentum" meaning silver in Latin, referring to its silver content, and "tennantite" which is also a mineral in the tennantite group.
Chemically, argentotennantite has a complex formula represented as (Cu,Ag)12As4S13. It typically forms in hydrothermal veins and is often associated with other sulfide minerals like pyrite, chalcopyrite, and sphalerite. Occasionally, it can also be found as a secondary mineral in oxidized copper sulfide deposits.
Argentotennantite crystals are usually opaque and exhibit a dark metallic luster. They commonly occur as striated prismatic crystals, but can also be found in granular or massive forms. This mineral ranges in color from grayish-black to iron-black. Its hardness falls within the range of 3 to 4 on the Mohs scale, indicating a relatively soft mineral.
Given its relative scarcity and limited occurrences, argentotennantite does not have significant industrial uses. However, as a mineral specimen, it holds interest for collectors and mineral enthusiasts due to its unique crystal morphology and the presence of precious metals such as copper and silver within its composition.
Etymology of ARGENTOTENNANTITE
The word argentotennantite is a compound term that combines two mineral names – argent and tennantite.
1. Argent comes from the Latin word argentum, meaning silver. It refers to the silver content or appearance of the mineral.
2. Tennantite is named after Smithson Tennant (1761-1815), a British chemist who discovered and studied various minerals. It is a copper-iron sulfide mineral that commonly contains silver and traces of other elements.
Therefore, argentotennantite is a specific type of mineral that combines the silver content of argent with the base mineral tennantite.
