sodalite उदाहरण वाक्य

Sodalite, colorless and transparent in thin section, but frequently pale blue in the hand specimens, is the principal feldspathoid mineral in addition to nepheline.
They then performed a complete chemical and structural analysis which confirmed that the substance indeed was a new feldspathoid species related to the cancrinite-sodalite group.
All minerals in the cancrinite-sodalite group have a similar framework, however, the number of layers of stacking are key in differentiating each mineral.
A cermet of depleted fissiable material ( e . g . uranium, plutonium ) and sodalite has been researched for its benefits in the storage of nuclear waste.
Within the group, there are various types of cages such as the cancrinite cages, the sodalite cages, the liottite cages, the losod cages among many.

Just outside the north-western corner of the park, there is an igneous intrusion known as the Ice River Complex containing deposits of sodalite, an ornamental stone.
It has been found in vugs in a carbonatite sill on Montreal Island and within sodalite syenite in the alkali intrusion at Mont Saint-Hilaire in Quebec, Canada.
Both examples show large rounded spots in the hand specimens; they are pseudoleucites, and under the microscope prove to consist of orthoclase, nepheline, sodalite and decomposition products.
The complex is noted for a wide variety of rare minerals and is the type locality for thirty minerals, including : aenigmatite, arfvedsonite, sodalite, eudialyte and tugtupite.
The sodalite family of minerals has a tetrahedral framework structure, with highly charged cations such as Al 3 + or Si 4 + connecting through a common O 2 ".
