4. Sedimentological analysis of the profile from the site Blatna Brezovica

Blatna Brezovica. Quantitative mineral composition of samples.

Abstract

Sedimentary sequence of the vertical profile at Blatna Brezovica was distributed to 9 samples. Quantitatively composition of samples was studied first. We also determined granulometric composition of all samples. In the deepest sample we also examined diatoms, which are the main indicator of sedimentation conditions. We were interested in characteristics of sediments and conditions in which they were depositing. We found three phases of deposition. The bottom samples belong to transitional lake-marsh sediment (the gyttia) with typical marsh sediments (peat) and humus following upwards. Comparison with "Na mahu 1" borehole indicates that all treated sediments are less than 7000 years old.

Keywords: granulometry, lake marl, peat, diatoms, Blatna Brezovica, the Ljubljansko barje, Slovenia.
