Vertical proportion curve of lithology. Only the carbonate fraction is considered in this plot, and the magmatic bodies are disregarded. The Contrin Formation is almost completely dolomitized, and the UCF and UTF are basically free from replacement dolomite. The lower part of the LPF shows a strong decrease in dolomite–limestone ratio and stagnates around 23%. This value is maintained up to the top of the LCF. In the MTF, the dolomite percentage drops to zero.
