Stratigraphy, geochemistry and origin of Silurian black graptolitic shales of the Carnic Alps.

Popis výsledku v původním jazyce

The distribution of major and trace elements in Silurian graptolitic shales of the Carnic Alps suggests important changes of depositional environment. With the beginning of the Silurian transgression and progressing subsidence, mostly chemically mature "siliceous" shales with generally higher Zr values were deposited in normal marine environment. The character of sedimentation has rapidly changed during Wenlock when chemically less mature calcareous shales together with carbonates dominated. The termination of basinal subsidence in Upper Silurian (Ludlow-Pridoli), has resulted in the deposition of chemically well mature graptolitic shales. Sulphidic graptolitic shales were mostly deposited in restricted marine environment (low O2 concentrations) with local periods of inhospitable bottom conditions (little or no O2 was present and H2S may have been continually or intermittently
