Abstract

We distributed sediments from two profiles, taken approximately 100 m from one another, to more levels (samples), studied them microscopically and appointed quantitatively mineralogical composition. Based on this analysis, granulometry and analysis of diatoms in levels chosen, we assumed on sedimentary environments. Total thickness of analysed sediments was not greater than 1.6 m (profile: SG-12). In this sedimentary sequence we distinguished the late lake phase of development, marsh phase of development and the humus sediments. Deposition of latter sediments is recent, i.e. after the Ljubljansko barje was dried out. It is interesting, that marsh sediments/peat lacks do not appear in profile SG-6, as the humus lies directly on top of gyttia.

Keywords: granulometry, lake sediments, marsh sedimentary, moor, humus, diatoms, Stare gmajne, the Ljubljansko barje, Slovenia.
