High-density nitrogen inclusions in barite from a giant siderite vein: implications for Alpine evolution of the Variscan basement of Western Carpathians, Slovakia

Abstract

Contrasting compositions and densities of fluid inclusions were revealed in siderite-barite intergrowths of the Drozdiak polymetallic vein hosted in Variscan basement of the Gemeric unit (Central European Carpathians).
