D Sedimentological profile through Pleistocene-Holocene deposits of Vela spila cave, Croatia Ljiljana Pavi i, Marta Mileusni, Dinko Radi, Ljerka Marjanac Vela spila cave is one of the most important archaeological and paleontological sites in Eastern Adriatic. It is situated on the Pinski rat hill near the town Vela Luka on the island of Kor ula, Croatia. Archaeological investigations in Vela spila cave have been going since 1949 and they have proved the continuity of human occupation of Vela spila through Palaeolithic, Mesolithic and Neolithic ( e uk & Radi, 2005). First sedimentological research was conducted in 2002, when the western profile of main trench was described and the distinctive tephra layer, dated from 15 ka ago, found (Radi et al., 2008). The trench has been extended during the archaeological excavations in 2004 and 2006. Sedimentological investigations were taken in 2008, in order to gain more information regarding the formation of sediments, as well as paleoenvironmental and palaeoclimatic conditions during deposition. Four stratigraphic profiles of main trench were drawn, and more than 40 samples were taken for laboratory analyses. Current investigations are based on detailed sedimentological (grain size analyses; microscopic analyses), geochemical (major, trace and rare earth element analyses; total sulphur and carbon determinations; carbonate and organic matter content, pH and electrical conductivity determinations) and mineralogical analyses (powder XRD analyses of bulk samples, as well as, XRD analyses of the random and oriented samples of clay fractions < 2 (m and cation exchange capacity determinations) of sampled fine grained sediment. Sedimentological and petrographical analyses of thin sections of carbonate clasts and grain size analyses will be performed on the samples of carbonate breccia. The laboratory analyses were concentrated on eastern profile called A-A' and here will be presented first preliminary results. Profile A-A comprises the whole range of Pleistocene deposits and the distinctive boundary layer between Palaeolithic and Mesolithic sediments. Most sediments are gravely-sandy-silt after Konta classification (Konta 1973), with abundant bone and coal content. The anthropogenic influence on sediment composition and structure is strong. Small fragments of charcoal and burnt bones, found in almost all sedimentary layers, as well as small carboniferous and clay lenses, found throughout the whole trench, probably represent ancient fire places. Lenses are concentrated defining a specific lenticular bed. Layers and thick lenses of very course-grained sediments (gravels and sandy-silty-gravels) contain recrystallised limestone clasts. These clasts are similar to those from cave walls, angular and platy in shape, with sharp edges. They are mostly remnants from the main rock disintegration and ceiling collapses, which had happened several times during the Pleistocene/Holocene period. Some layers comprise a great quantity of large animal bones and bone fragments. The boundary between Pleistocene and Holocene (Palaeolithic and Mesolithic) is marked with distinct matrix supported gravels. Limestone clasts and boulders have irregular shape and sharp edges and are very poorly sorted. Reddish-brown fine-grained matrix is concentrated mostly in the upper part of the bed. The layer beneath show great deformations because of the large limestone blocks falling and crushing into a soft fine-grained silty sediment bellow and causing the thin carboniferous and clay lenses to disturb and form deformation structures. This layer is recognizable in whole trench and marks a period of almost 5000 years without a human presence in Vela spila cave (results from the radiocarbon dating of sediments above and below that layer). Mineralogical content of sediment samples is represented by carbonates (calcite and dolomite), quartz, apatite (bones) and sporadically by plagioclase and K-feldspars. Dolomite is found only in deeper part of the profile. Organic matter content vary between less than 1 to 10 wt. %. Purpose of the current study is not only to achieve the goal mentioned in the introduction, but also to create a template for investigation of other similar caves in Croatia.
