Mineral Species: Sulphur and Aragonite
Chemical Formula: S
Chemical Name: Sulphur
Mineral Class: Native Element
Mineral Notes: Sulphur belongs to the non-metals. Its crystal structure consists of ring-shaped S8 molecules linked together by weak molecular forces. It is most commonly formed and found in volcanic regions where it is precipitated directly from Sulphur-rich gasses, a process called sublimation. It can also be formed by the incomplete oxidation of Hydrogen Sulphide gas. The last source comes from sulphates which are converted by bacterial activity.
Description: A mixture of Sulphur and Aragonite lining a cavity running through matrix. The mineral combination has an unusual silver-brown colour and botryoidal form. Yet it is highly highly crystalline which makes the minerals highly lustrous. Overall, a very unusual and attractive specimen.
Location: Machow, Poland.
