vasszulfid

Vasszúlfid is a sulfide mineral composed of iron and sulfur. It is a rare mineral, found primarily in Hungary, where it was first discovered. The mineral has a chemical formula of (Fe,Ni)9S8 and is a member of the pentlandite group of minerals.

Vasszúlfid is characterized by its complex crystal structure, which is typically yellowish-white in color and has a metallic luster. The mineral is often found in association with other sulfide minerals, such as pentlandite and pyrrhotite, and is commonly associated with igneous and metamorphic rocks.

The name "vasszúlfid" is derived from the Hungarian words "vaszúlf" meaning iron-sulfur, which refers to the mineral's composition. The mineral was named by Hungarian geologist Ferenc Zipser in 1973, when he first discovered it in the Bakony Mountains of western Hungary.

Vasszúlfid is of interest to geologists and mineralogists due to its unique composition and crystal structure. Despite its rarity, the mineral has been the subject of several scientific studies, which have shed light on its formation and distribution.

In terms of its occurrence, vasszúlfid has been found in limited quantities in Hungary, as well as in other parts of the world, including the United States and Canada. The mineral's rarity and limited distribution have contributed to its relative obscurity in the scientific community.
