How Do You Spell PERRYITE?

1. Perryite is a mineral that belongs to the dendritic or dendritic-vein mineral group. It is specifically classified as a sulfosalt, which means it is composed of sulfur and metallic elements. Perryite is primarily composed of iron, arsenic, and sulfur, with chemical formula Fe2+AsS. It typically forms as a black or dark gray mineral with a metallic luster.

   Perryite has a monoclinic crystal structure and can be found in metamorphic rocks, especially those formed in high-temperature environments like hydrothermal veins. It is commonly associated with other sulfide minerals such as chalcopyrite, pyrrhotite, and pyrite.

   The mineral was named after its discoverer, Frederick Lynn Perry, an American meteorologist and mineralogist. It was first identified in samples collected from the Hibbing Taconite Mine in Minnesota, United States, where it occurs in close association with magnetite.

   Perryite is of significant interest in scientific research, particularly in the study of meteorites and impact structures. It is often found in iron meteorites and is considered an important mineral for understanding the formation and history of these extraterrestrial objects.

   In summary, perryite is a sulfosalt mineral made up of iron, arsenic, and sulfur. It has a metallic luster and is commonly found in metamorphic rocks, particularly associated with magnetite. Its notable occurrence in iron meteorites makes it an important mineral in the investigation of these celestial bodies.

The word "perryite" is derived from the name of Professor John Perry, an English mathematician and physicist who lived from 1850 to 1920. Perry made a significant contribution to the field of seismology and studied the properties of seismic waves. As a result, a mineral was named after him to honor his work. Perryite is a rare iron-manganese sulfide mineral, first identified in 1894, and it was named in recognition of John Perry's contributions to the field of geophysics.
