Withérite est un minéral de carbonate de baryum, BaCO 3, dans le groupe aragonite. La Witherite cristallise dans le système orthorhombique et est pratiquement toujours jumelée. Le minéral est incolore, blanc laiteux, gris, jaune pâle, vert à brun pâle. La densité est de 4,3, ce qui est élevé pour un minéral translucide.

Introduction: witherite occurs typically, along with baryte and other Ba-bearing minerals, in low-temperature hydrothermal mineral veins, frequently of Mississippi Valley type (MVT) affinity. Other commonly associated mnerals include calcite, sphalerite and galena. Witherite is identified by the fact that it is very dense for a nonmetallic mineral (a …
It's quite rare to find a specimen with a 4.0 cm Witherite like this, and I love the fact that it's so perfectly set at the top most portion of the specimen. A great example of this now incredibly hard to find high quality material. From the collection of Henry de Linde (March 21, 1923 – April 4, 2019) of Hot Spring, Arkansas.

Witherite is a barium carbonate mineral, BaCO 3, in the aragonite group. [1] Witherite crystallizes in the orthorhombic system and virtually always is twinned. [1] The mineral is colorless, milky white, grey, pale yellow, green, to pale brown. The specific gravity is 4.3, which is high for a non-metallic mineral.

This is an impressive, lustrous Witherite cluster that easily competes with any other specimen in its size range. When we think of Witherite, Cave-In-Rock, Illinois and and Alston Moor, England immediately come to mind, not Shaft 371 in Hartenstein, Germany. In fact mindat only has one photo of Witherite from this locality!
