Provenance of Würmian loess and loess-like sediments of Moravia and Silesia (Czech Republic): a study of zircon typology and cathodoluminiscence

Rok, strany: 2006, 397 - 403

A detailed zircon study (typology and cathodoluminiscence) of late Pleistocene (Würmian) loess sediments from Moravia area, Czech Republic shows a significant western provenance from magmatic (mainly granitic) rocks of Bohemian Massif together with contributions from metamorphic rocks. Zircon typology is applicable only for well-preserved magmatic zircon crystals, which usually occupy a part of the whole zircon population. Zircon typology indicates a dominant provenance from calc-alkaline I-type granites, whereas important contributions of material from S-type granites (Moldanubian pluton?) is not documented. The provenance material of the Velka Bites locality is derived from the adjacent melanosyenitic rocks (durbachites) of the Trebic Massif and in this case confirms transport over a short distance as well as provenance from the west. Cathodoluminiscence images indicate both magmatic and metamorphic origin of the studied zircon.
