Terrestrial laser scanning and electrical resistivity tomography as combined tools for the geoarchaeological study of the Kritsa-Latô dolines (Mirambello, Crete, Greece)

摘要: A complex of enclosed karst depressions near Kritsa-Lato (Dikti Mountains, Eastern Crete) was analysed with regard to its surface and subsurface topography using a new multi-method approach. Based on combination terrestrial laser scanning, electrical resistivity tomography geographic information systems, crucial geophysical morphometrical parametres were derived correlated sedimentological results in order provide first-time insights into the formation, size archive function dolines. High-resolution digital elevation models (0.25 m, 2 m) allowed conducting topographical analyses special respect micro-relief attributes traces former land use, as well placing all findings 3D context for enhanced interpretation. As shown by results, both limestone dissolution local tectonics led development an extensive sediment trap, whose is characterised distinct three-part segmentation. Above bedrock, highly fractured epikarst zone exhibits features typical buried such subterraneous sinkholes pinnacles. In contrast, near-surface section completely consists fine-grained, loamy substrates. Despite thicknesses up 25 loose infilling entirely lacks stratification therefore indicates permanent low energetic colluviation processes under rather stable geomorphodynamic conditions during Quaternary. human impact, several anomalies suggest existence ancient water harvesting system, which quite likely dates back Minoan or Dorian times. supply must be considered essential agricultural purposes karstified mountains Crete, Kritsa dolines have served favourable locations settlement use purposes. With help multi-technique approach, geomorphological geoarchaeological characteristics study area could captured.

Combining scanning tomographical mapping proves particularly suitable integral prospecting promises substantial potential future studies.
