Chemical composition of Kiscellian silty sediment (sivica) from the Trohni Dol area, Eastern Slovenia

Abstract

Kiscellian marine silt termed »sivica« is widely developed in Tertiary basins of Eastern Slovenia. Chemical composition is rather uniform and reflects the dominance of filosilicates (mainly illite/muscovite, chlorite and montmorillonite) and carbonates. PAAS normalised REE and Y abundances are slightly depleted for La, Ce, Pr and Nd very close to PAAS for Sm, Eu, Gd and Tb, and depleted for Y, Ho, Er, Tm, Yb and Lu.
