MINERALOGICAL AND BIOLOGICAL WITNESSES OF REDIKAR BURIAL OF THE 10TH–11TH CENTURIES

The study of products copper alloys the Lomatov culture X-XI centuries from collection Cherdyn Museum revealed two types patina. first pseudomorphic might be composed intergrowths chlorides formed upon interaction with sweat hands, or a zonal rim cuprite-malachite-azurite composition, due to groundwater. second type, which distorts shape original product, is associated leaching and other metals crystallization oxides salts on surface in form worm-like, kidney-shaped drusoid aggregates. Fragments mineralized biological objects (wings, eggs larvae flies, mole hair) found patina testify rapid oxidation bronze, flooding soil burial ground immediately after burial.
