Figures & Tables

Figure 1.

Location of the research area (A); the studied gullies superimposed on a background of the Vilnia valley (B); gully catchments and the main relief forms (C); and the location of drillings on the gully fans (D)Source: Geoportal.lt [29 October 2023]

Figure 2.

Longitudinal and cross-sectional profiles of the studied gullies (dashed line - cutting of the fan after building a culvert under the road); m asl - meters above sea levelSource: Geopoprtal.lt [29 October 2023]

Figure 3.

Granulometry, sedimentological indicators, and loss on ignition (LOI) for the sediments of gully fans I (A) and II (B), in depth profiles: Mz - mean grain size in phi scale, σ1 - standard deviation as sorting index, Sk1 - skewness, KG - kurtosis; 14C dating - cal. years AD; drilling locations as shown in Fig. 1D; a, b, c - lithological units (explanation in the text)Source: own study

Figure 4.

Relationship between mean grain size (Mz) and sorting index (standard deviation-σ1) in phi scale, with trends for fluvial channel/gully sediments (solid line) and overbank/colluvial sediments (dotted line): drillings 2–7, a - upper lithological unit (accumulated since the seventeenth century), b - middle lithological units (early modern times), c - lower lithological units (Middle Ages)Source: own study

Radiocarbon age of the studied fans at the mouth of the gullies (conventional dating), calibrated OxCal v_ 4_4_4 (Reimer et al_ 2020; Bronk Ramsey 2021)
