Potassium-rich dyke rock of Rogówek (Sudetes, Poland)

Wierzchołowski B.

Archiwum Mineralogiczne

2001

T. 54

77-97

Vogesites, microsyenites and alkaline microsyenites have been found to occur within the Kłodzko – Złoty Stok granitoid massif. Trace elements identified in these rocks have been used to construct spider diagrams. In vogesites, metamorphic and mag-matic amphiboles have been identified, the co-occurrence of which suggests that these rocks have been formed due to mechanical and chemical contamination of syenitic mag-ma with material rich in metamorphic amphiboles. In the Rogówek dyke rocks, the am-phiboles crystallized from melt represent winchite, richterite and magnesio-arfvedsonite in composition. Geochemical data suggest that this magma was generated in within-plate continental environment.
