sodalite การใช้

• Biotite, cancrinite and sodalite are characteristic of this rock.
• It is essentially a microcline, sodalite and cancrinite variety of nepheline syenite.
• Although massive sodalite samples are opaque, crystals are usually transparent to translucent.
• Most sodalite will fluoresce orange under ultraviolet light, and hackmanite exhibits tenebrescence.
• Sodalite or hauyne may also be present, but nepheline is typically absent.
• Sodalite transforms into cancrinite when exposed to high temperature.
• Eventually, sodalite is found along hydrothermal fractures.
• I've went ahead and created sodalite with the new facto / infobox.
• These last consist of an intermixture of nepheline or sodalite and alkali-feldspar.
• There is a sodalite mine to the east.
• Zgonis points out Royal Blue Sodalite from Zimbabwe and a Verde Fire Granite from Australia.
• It may also be substituted by spinel or sodalite, or by dyed jasper or howlite.
• Sodalite is a member of the sodalite group with hauyne, nosean, lazurite and tugtupite.
• Sodalite is a member of the sodalite group with hauyne, nosean, lazurite and tugtupite.
• Sodalite's six directions of poor cleavage may be seen as incipient cracks running through the stone.
• Nepheline is very abundant and there is also cancrinite, sodalite, scapolite, calcite, biotite and hornblende.
• Of these the former consists of orthoclase, nepheline, sodalite, diopside and aegirine, biotite and sphene.
• In high temperature, sodalite would transform to cancrinite of which twelve-ring channels cage prefer bigger cation.
• In nature it is frequently altered to zeolites ( especially natrolite ), sodalite, kaolin, or compact muscovite.
• "' Sodalite "'is a rich royal blue tectosilicate mineral widely used as an ornamental gemstone.
