Is Chabazite a mineral or rock?

Is Chabazite a mineral or rock?

Chabazite, one of the dominant zeolites in altered volcanic deposits, is the principal member of a group of zeolite minerals that have very similar modes of occurrence, chemical and physical properties, and internal structures.

Where is Chabazite found?

Chabazite occurs most commonly in voids and amygdules in basaltic rocks. Chabazite is found in India, Iceland, the Faroe Islands, the Giants Causeway in Northern Ireland, Bohemia, Italy, Germany, along the Bay of Fundy in Nova Scotia, Oregon, Arizona, and New Jersey.

What is mordenite zeolite?

Mordenite is a zeolite mineral with the chemical formula, (Ca, Na2, K2)Al2Si10O24·7H2O. Mordenite is orthorhombic (a,b,c unequal & all angles 90 degree). It crystallizes in the form of fibrous aggregates, masses, and vertically striated prismatic crystals. It may be colorless, white, or faintly yellow or pink.

Is zeolite A metal?

Zeolite, any member of a family of hydrated aluminosilicate minerals that contain alkali and alkaline-earth metals. The zeolites are noted for their lability toward ion-exchange and reversible dehydration.

Where can you find a bronze colored chabazite?

– A bronze-colored Chabazite once found in the gneiss of the Jones Falls area in Baltimore, Maryland. – Synonym of Chabazite-Na. This was the official name of the mineral prior to the renaming of Chabazite into a series by the Zeolite Subcommittee of the IMA.

What is the Si Al ratio of chabazite?

Synthetic chabazite. Many different materials that are isostructural with the chabazite mineral have been synthesized in laboratories. SSZ-13 is a CHA type zeolite with an Si/Al ratio of 14.

What’s the difference between gmelinite and chabazite?

A distinction among the different Chabazite types is rarely made, and the members are generally just termed Chabazite without further breakdown. Chabzite is very similar in structure and habit to the closely related Gmelinite. Gmelinite often forms as a pseudomorph after Chabazite, retaining the original rhombic shape but forming modified faces.

How is the zeolite mineral chabazite classified?

The Mineral chabazite. In 1997, the Zeolite Subcommittee of the IMA divided this mineral into individual sub-species, thereby regarding Chabazite as a series of four members. The series is defined by the presence of several variable elements in the following order: calcium, sodium, potassium, and strontium.
