The article presents data from statistical processing of published elemental compositions of bronze pandantive amulets from Pecheneg burials of the 11th–12th centuries in the Lower Danube region, compared with (1) the author’s estimated topomineralogical maps of Bulgaria, obtained by processing data on heavy mineral concentrates, (2) the geological and geomorphological situation in the region under consideration, and (3) data on the thermal field of Northern Bulgaria. It is assumed that the findings of pandantives are a possible indication of the presence of mineralizations of copper, tin, lead, zinc, antimony, bismuth, gold, mercury, chromium, and cobalt in the Varna-Silistra region.
