Actinocrinite is a mineral that belongs to the zeolite group. It is a rare mineral that is primarily found in volcanic rocks. Actinocrinite is known for its unique crystal structure and its ability to absorb water and other liquids. In this article, we will explore the definition, origin, meaning, associations, synonyms, antonyms, and example sentences of actinocrinite.
Definitions
Actinocrinite is a mineral that is composed of calcium, sodium, aluminium, silicon, and oxygen. It is a zeolite mineral that has a unique crystal structure. The chemical formula of actinocrinite is Ca2Na2Al4Si8O24·7H2O.
Origin
Actinocrinite was first discovered in 1818 by the German mineralogist Johann Friedrich Ludwig Hausmann. The mineral was named after its unique crystal structure, which resembles a star (actino is Greek for star). Actinocrinite is primarily found in volcanic rocks, such as basalt and andesite.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, actinocrinite is defined as “a mineral consisting of a hydrous silicate of calcium, sodium, and aluminum that occurs in white or grayish masses and has a radiating fibrous structure.”
The Oxford English Dictionary defines actinocrinite as “a mineral of the zeolite group, consisting of a hydrous silicate of calcium, sodium, and aluminum, occurring in white or grayish masses with a radiating fibrous structure.”
Associations
Actinocrinite is often associated with other minerals, such as analcime, chabazite, heulandite, and stilbite. It is also commonly found in volcanic rocks, such as basalt and andesite.
Synonyms
Some synonyms of actinocrinite include:
- Star zeolite.
- Radiated zeolite.
- Radiating zeolite.
- Fibrous zeolite.
Antonyms
As actinocrinite is a mineral, it does not have any antonyms.
The same root words
The root word of actinocrinite is actino, which means star. This root word is also found in other words, such as actinolite (a mineral) and actinometer (an instrument for measuring the intensity of radiation).
