Abstract

Close association of peralkaline vitric crystal tuffs (welded) with the massive dark grey stratified barytes deposit is reported. Megascopic and microscopic description of the rocks reveal that these rocks are of eruptive origin.

Chemical analyses of three representative rock samples are given. Peculiar chemical characteristics are discussed.
