A combination of sedimentological and mineralogical methods with emphasis on heavy mineral assemblage research applied to allochthonous sediments in the Liskovská Cave located in the western part of the Liptovská Basin (in the tectonic horst composed of Triassic limestones at foothills of the Chocské vrchy Mts.) were used for the identification their provenance and sedimentary history. Allochthonous fine-grained mud was studied in three profiles (LI-1 to LI-3). The sediments originated from the suspension in slow water flow to stagnant water (slackwater facies). This material could be later redeposited during the younger flooding event and small-scale slumps and gravity flows (mudflows) have been locally generated on steeper cave floors. Based on mineralogical study the cave sediments are composed of quartz, muscovite, calcite, chlorite, K-feldspar, plagioclase and dolomite. A heavy mineral assemblage is formed by garnet, zircon, apatite, monazite, tourmaline, staurolite, amphibole, rutile, titanite, epidote, sillimanite, allanite, andalusite, pyroxene and xenotime. Opaque minerals are represented by ilmenite, pyrite, magnetite, Cr-spinel, hematite, Cu-sulfides and Feoxyhydroxides. Their mineralogical character indicates the heterogenous source material which was transported by the Váh River. The results are significant for a more accurate reconstruction of origin and development of the cave, mainly its sedimentary phases in Middle and Late Pleistocene related to floods from the adjacent river bed.
