Mechanism of plagioclase albitization

Journal of Sedimentary Research, 1992
Abstract Observations of closely spaced porous and cemented sandstones from the San Joaquin basin, the Los Angeles basin and the Gulf Coast reveal that albitization of plagioclase occurs during fracturing of the detrital plagioclase grains.

ALBITIZATION OF GRANITIC ROCKS: THE MECHANISM OF REPLACEMENT OF OLIGOCLASE BY ALBITE

The Canadian Mineralogist, 2008
Large-scale metasomatic albitization in the albitite terranes of the Bamble sector of southeastern Norway has affected both mafic and granitic lithologies. In partially metasomatized tonalite, the albitization fronts advance normal to fractures and can be recognized in the field by a distinct reddening of the rock in which original plagioclase crystals

Staining of albite

Geologiska Föreningen i Stockholm Förhandlingar, 1980
Abstract Staining of thin sections for quick identification of quartz, potash feldspar and plagioclase is usually done with sodium hexanitrocobaltate (III) and rhodizonic acid disodium salt. This method is unsatisfactory when the anorthite content of the plagioclase is low.

Dissolution process of albite and albite glass in acid solutions at 47°C

Chemical Geology, 1985
Dissolution of albite and albite glass powders in 0.01, 0.001 and 0.0001 N HCl solutions at 47°C was studied by a non-buffered method. Chemical analysis of the solutions showed that they dissolved rapidly and incongruently in the initial stage, and that the dissolution rate decreased and approached to congruence in the next stage.

Albite and gold

Economic Geology, 1940
A search of the literature reveals an imposing number of gold deposits from many parts of the world that are genetically related to albite-rich igneous rocks. The evidence suggests that these deposits contain little silver and the sulphides are simple and not abundant, whereas gold deposits genetically related to potash rich rocks are argentiferous ...

Analcime-albite equilibria

American Journal of Science, 1965
New data are presented that suggest the reaction analcime+quartz=albite+liquid water is in equilibrium near 190 degrees C or possibly at even lower temperatures. On the basis of these data, a phase diagram showing the field of stability of the assemblage analcime-quartz is constructed. The delta G degrees of the above reaction estimated from these data
