Qurtz-egiriene-microcline metasomatites: conditions buildups, minerageny

Abstract

Qurtz-egirine-microcline metasomatites related to independent metasomatic formation. They formed in the conditions display of processes silicon-iron-potassium metasomatism on areas of distribution rocks alkaline-granite and alkaline-syenite series, fenites and microcline-sericite metasomatites. Defined conditions formation and minerageny (precious-metals, rare-metals, rare-earth mineralization) qurtz-egirine-microcline metasomatites in the massif of Central Aldan, West Aldan, Urals alkaline province.
