Abstract (in english)
   Relationships between geochemical anomalies, sea-level change and other events were studied in the Cenomanian-Turonian boundary interval in the Pecínov (Hořkovec) quarry in southwestern part of the Bohemian Cretaceous Basin (Czech Republic). Isotopic composition of marine/terrestrial organic matter in relation to paleoenvironmental indicators was studied. Abudances of Ir, Sc, Cr, V and other elements previously reported as forming anomalous concentrations in the boundary interval showed no enrichment in the Bohemian section. This is most probably due to the large distance of the depositional site from the presumed volcanic source of element-enriched deep waters in the proto-Caribbean region. Anomalous concentration of Mn at the base of the Turonian deposits was caused by diagenetic incorporation of Mn into siderite
