[ 1 ] - Chemistry of minerals and mass changes of elements during sodiccalcic alteration of the Panj-Kuh intrusive body (Damghan, Iran)

Exact petrography and mineral chemistry investigations of pristine and altered rocks of the post-Eocene Panj-Kuh pluton show thatsubsequent to emplacement and crystallization, rocks were subjected to two secondary composition equivalents, sodic-calcic andpotassic alterations, respectively. Fresh rocks have syenitic composition and contain plagioclase (labradorite), K-feldspar, magmaticdiopside,...
