Geological setting, petrology and mineralogy of metabasites in a thermal aureole of Tanvald granite (northern Bohemia) used for the manufacture of Neolithic tools

Popis výsledku v původním jazyce

This study examined the metabasites in a thermal aureole of the Tanvald granite in the northern part of the Bohemian Massif that were used for manufacturing Neolithic tools. The metabasites form relatively thin bodies from several cm to 2 m thick and areintercalated conformably within the host metasedimentary rocks. Two types of thermally metamorphosed actinolite-hornblende hornfelses (metabasites) were distinguished: 1) fine-grained amphibole-rich metabasite and 2) metabasites with relicts of porphyritic texture. Because of their large lateral extent and geological setting within metasediments, fine-grained metabasites may correspond to former volcanoclastic rocks (meta-tuffs), while the porphyritic metabasites probably represent metamorphosed dolerite sills or dykes. The host rocks are various types of cordieritebiotite spotted schists or andalusite-cordierite-biotite hornfelses. Both groups of metabasites consist of several types of amphiboles, calcic plagioclase (andesine to labra
