Albite - minéraux à cristaux L' ALBITE appartient au groupe des silicates. Elle contient du sodium, de l'aluminium et su silicium. C'est un aluminocate de sodium. Sa formule est Na Al Si3 O8. L' ALBITE constitue un des extrèmes de la série des plagioclases (l'autre étant l'anorthite) et des feldspaths (l'autre étant l'orthose).

L'albite est le pôle sodique de la série des feldspaths plagioclases, dont l' anorthite constitue le pôle calcique. Dans cette série, l'albite correspond à : Ab 90-100 % An 0-10 %, (où Ab = albite, et An = anorthite]]). Sa teneur en silice en fait un plagioclase acide.

A albita (português brasileiro) ou albite (português europeu) é um mineral, pertencente à família dos feldspatos plagioclásicos. É o extremo sódico da série das plagioclases, não contendo mais de 10% de anortita.Quando pura tem composição química NaAlSi 3 O 8. É um tectossilicato.Quase sempre exibe maclas, geralmente sob a forma de estrias na face do cristal.

ALBITE FELDSPAR BACKGROUND INFORMATION. Albite (NaAlSi 3 O 8) is the pure Na (sodium) feldspar.In the earth's crust, feldspars are more abundant than all other minerals combined. The majority of the common feldspars fall into two groups, the alkali feldspars (KAlSi 3 O 8 through NaAlSi 3 O 8 series), and the plagioclase feldspars (NaAlSi 3 O 8 …

Albite is a widely distributed white feldspar commonly found in granites, syenites, rhyolites, and trachytes, as well as pegmatites and spillites. Because albite is the last of the feldspars to crystallize from molten rock, it may often be found with other rare minerals. Major occurrences of albite can be found in Labrador, Canada, and the ...

In Developments in Geochemistry, 2007. 6.6.4.2 pH dependence of the dissolution kinetics of feldspars. Albite. Figure 6.29 shows that the dissolution rate of albite is strongly dependent upon pH and temperature. At all temperatures, from 5 to 300°C, the dissolution rate is at a minimum in the neutral range and increases in both the acidic- and basic-pH intervals.

RSS. Albite mineral gemstone is a natural stone belonging to the group of plagioclases, is the main type of feldspar. It is a mineral that is most often found in the form of twin intergrowths in igneous, infusional and intrusive rocks of igneous origin.Its crystals have a transparent, translucent and opaque structure with a glass luster.

ITA-D62 ELBAITE, K-FELDSPAR & ALBITE. SAN PIERO, ISOLA ELBA, ITALY - Close to several light pink k-feldspar crystals there is a well termianted bicolor elbaite. The elbaite is 0.8 cm. There are also several other elbaite of 2 and 5 mm spead around the specimens, partly hidden by nice white albite crystals. The feldspars are up to 1-1.5 cm across.

Albite: Occurrence and Identification. Albite is a plagioclase feldspar mineral. It belongs to the Plagioclase Feldspar group, an isomorphous solid solution series. It is the sodium endmember of the plagioclase solid solution series. As such it represents a plagioclase with less than 10% anorthite content. Albite usually forms brittle, glassy ...

On voit que l'albite est stable pour des concentrations en Na+ et silice élevée; quand ces concentrations deviennent faibles, l'albite est totalement hydrolysée en gibbsite, hydroxyde d'aluminium de formule Al(OH)3 (ou Al2 O3, 3 H 2 0) ; pour des teneurs moyennes, elle est hydrolysée partiellement et se transforme en kaolinite ou en ...

Bourg d'Oisans and Isere, France. Name Origin: From the Latin, albus, in allusion to the common color. Albite is a plagioclase feldspar mineral. It is the sodium endmember of the plagioclase solid solution series. As such it represents a plagioclase with less than 10% anorthite content. The pure albite endmember has the formula NaAlSi 3 O 8.

Moonstone is a highly desirable combination of albite and orthoclase which give it colorful sheen inside the mineral. It is a common collector gem, since albite has a hardness of 6-6.5, and it is usually too fragile for jewelry, so they must be sanded down or …

On substitue deux par deux (deux charges négatives apparaissent) ; on compense la charge électrique par un cation bivalent : anorthite.

Albite is a very common mineral, but localities where fine Albite crystals can be found are more limited. Some excellent examples have come from the Swiss Alps and the Tyrol, Austria. Large, well formed crystals come from the pegmatite s of Gilgit, Pakistan; and Nuristan, Afghanistan.

albite, common feldspar mineral, a sodium aluminosilicate (NaAlSi3O8) that occurs most widely in pegmatites and felsic igneous rocks such as granites. It may also be found in low-grade metamorphic rocks and as authigenic albite in certain sedimentary varieties. Albite usually forms brittle, glassy crystals that may be colourless, white, yellow, pink, green, or black.
