basis: The isotopic composition of the Triassic limestone bedrock is characterized by relatively low oxygen isotope values (between -4.0 and -6.0%; average d18Ocalcite = -5.3%)...samples from units 6, 5 and 3 show d18Ocalcite values (-7.1% to -3.2%) similar to the isotopic signal of the bedrock (-4.6% to -5.2%), indicating a dominant clastic origin of the carbonate.

basis: In the absence of contamination sources [units 1,2 4a and 4b], the two primary factors controlling d18Ocalcite values are moisture balance (precipitation minus evaporation) and the isotopic composition of lake waters (Griffiths et al. 2002)
