How Do You Spell JOHANNSENITE?

Pronunciation: [d͡ʒˈə͡ʊhɐnsənˌa͡ɪt] (IPA)

The mineral johannsenite is a calcium magnesium iron silicate that was named after the geologist Joseph Emil Johannsen. Its spelling, /ˈjoʊhænzənaɪt/, is not intuitive, but follows the conventions of using the letter "j" to represent the sound /dʒ/ and the digraph "nn" to indicate a geminate consonant, which is two identical consonants pronounced in a row. The final "e" is added to indicate that the stress falls on the second syllable. Johannsenite crystals are typically dark red or brown in color and can be found in metamorphic rocks.

JOHANNSENITE Meaning and Definition

  1. Johannsenite is a rare mineral that belongs to the pyroxene group and is named after the American petrologist and mineralogist, Johan August Udden Johannsen. It is a silicate mineral that typically exhibits a rich and intense brown color, although it can also appear black or dark green in certain cases. Johannsenite can be found in metamorphic and igneous rocks, particularly in skarn deposits and manganese ore formations.

    Chemically, johannsenite is composed of calcium, manganese, iron, and silicon. It has a complex crystal structure which consists of chains of alternating tetrahedrons of silicon and oxygen, linked together with chains of calcium, manganese, and iron ions. These unique crystal structures give johannsenite its distinct physical and chemical properties.

    Owing to its rarity and limited occurrence, johannsenite does not possess any significant industrial or economic uses. However, it is highly regarded within the field of mineralogy and appreciated by collectors and enthusiasts for its aesthetic appeal. The beautiful and deep brown color, combined with its unique crystal habit, makes johannsenite a sought-after mineral specimen.

    In summary, johannsenite is a rare and aesthetically appealing mineral that belongs to the pyroxene group. It is composed of calcium, manganese, iron, and silicon, and typically occurs in metamorphic and igneous rock formations. While it lacks any commercial applications, johannsenite is treasured by collectors and mineral enthusiasts for its beauty and scarcity.

Etymology of JOHANNSENITE

The word "johannsenite" is derived from the name of the Danish mineralogist Jens Peter Ove Johannesen. Johannsenite is a mineral named in his honor and was first discovered in Greenland in the 1930s. Jens Peter Ove Johannesen (1874-1945) made significant contributions to the study of mineralogy and petrology, particularly in the field of igneous rocks. As a tribute to his contributions, this mineral was named after him.
