METAKIRCHHEIMERITE Meaning and Definition

1. Metakirchheimerite is a mineral that belongs to the sulfide group and is classified as a rare secondary mineral. It is named after its discovery locality in the Kirchheim mine in Germany. The mineral typically occurs as small, tabular, or prismatic crystals, often in radiating aggregates or crusts.

   Metakirchheimerite has a distinctive bluish-green color, with a vitreous to resinous luster. Being a sulfide mineral, it is composed of the chemical elements lead (Pb), copper (Cu), antimony (Sb), and sulfur (S). The chemical formula of metakirchheimerite is Pb₁₀Cu₃(Sb₂S₁₁)₂S₂₃.

   In terms of its physical properties, metakirchheimerite has a relatively high specific gravity, ranging from 6.9 to 7.1. It also exhibits a significant hardness, measuring approximately 2.5-3 on the Mohs scale.

   Metakirchheimerite is often found associated with other minerals such as galena, sphalerite, tetrahedrite, and other lead and copper sulfides. It typically forms in hydrothermal ore deposits under low-temperature conditions.

   Due to its rarity and unique crystal habit, metakirchheimerite is of interest to mineral collectors and enthusiasts. However, its limited occurrence and small crystal size make it less commercially valuable. Its distinctive color and crystal structure contribute to its identification, although analytical techniques like X-ray diffraction and electron microscopy are often required to determine its exact composition.

Etymology of METAKIRCHHEIMERITE

"Metakirchheimerite" is a compound word derived from combining the terms "meta-" and "Kirchheimerite".

The prefix "meta-" is derived from the Greek word "metá" which generally denotes a change, transformation, or alteration. In the context of mineralogy, "meta-" is used to indicate that a specific mineral has undergone metamorphism or a transformation due to heat, pressure, or chemical reactions.

"Kirchheimerite" is derived from the name of the locality where the mineral was first discovered. It is named after Kirchheimbolanden, a town in the Rhineland-Palatinate region of Germany. The suffix "-ite" is a common mineralogical suffix used to denote minerals.

Therefore, "metakirchheimerite" indicates that the mineral "Kirchheimerite" has undergone some form of transformation or alteration.
