adularization

[…] albite, calcite, and pyrite -- are compounds of magnesium, sodium, calcium, and iron, which are the principal elements removed during adularization. The peripheral relation of the chloritized rocks to the adularized rocks […]

Adularization is most intense near the centers of mineralization. Silicification and bleaching of the bedded tuffs are pervasive and widespread , causing the rock to be easily mistaken for rhyolite (Emmons, 1910, p. 59).

Adularization is developed mainly in amygdaloidal, upper fragments of the flows of the so-called melaphyres, along dysjunctive zones or endocontacts of larger intrusions, but wholly confines smaller igneous bodies (e.g., dikes of ...

Mineralogically , the metasomatic alteration is marked by incipient to total adularization of primary phenocrysts of monoclinic K - feldspar (total), of plagioclase (incipient to total) , as well as of feldspars in the matrix ...

This is supported by the disappearance of cracks and cleavages in feldspars that suffered adularization. We conclude that oil impregnation occurred prior to (or partly during) adularization.
