L’intervisibilità. Analisi del paesaggio nella chora della colonia greca di Himera

2016

This study focuses on the analysis of the landscape in the territory of the colony of Himera. In particular, this work is inspired by a detailed examination conducted on the basis of parametric modelling, which has helped us to understand what factors (pedology, altimetry, geology, supply basins, etc.) had an effect in the settlement choices of the Imerese territory during the Colonial Age. We analysed the role intervisibility had between sites in the organisation of the landscape. By avoiding a deterministic logic, we intersected the data from previous surveys on the development of predictive models with the archaeological data, formulating hypotheses on the role that the main settlements …

Pollen and Plant Macroremain Analyses for the Reconstruction of Environmental Changes in the Early Metal Period

2006

A sharp increase in human population density and the same time fundamental changes in the location of settlement, moving away from earlier inhabited places points to significant changes in the environment. This period with a sharp decrease in anthropogenic indicators and poor records of slash and burn cultivation and field crop-growing is named “transition” period (Vasks et.al.1998) and indicates the lack of stable and continuous inhabitant sites. This phenomena can be explained by the small size of settlements at the Early Iron Age, expressed by a weak cultural layer and these could be defined as separate farmsteads. Modern farming practices, especially modern tillage, adversely affected t…

Sensitivity of the C-band SRTM DEM Vertical Accuracy to Terrain Characteristics and Spatial Resolution

2008

This work reports the results of a careful regional analysis of the SRTM DEM (Shuttle Radar Topography Mission – Digital Elevation Model) vertical accuracy as a function of both topography and Land-Use/Land Cover (LULC). Absolute vertical errors appear LULC-dependent, with some values greater than the stated accuracy of the SRTM dataset, mostly over forested areas. The results show that the structure of the errors is well modeled by a cosine power n of the local incidence angle (θloc). SRTM quality is further assessed using slope and topographical similarity indexes. The results show a lower relative accuracy on slope with a R2 = 0.5 and a moderate agreement (Kappa ≈ 0.4) between SRTM- and …

Intrasite Artefact Survey at Terravecchia di Cuti (Sicily)

2016

In this paper, we discuss the results of an artefact survey and a sampling collection in the indigenous settlement of Terravecchia di Cuti, in the chora of the Greek colony of Himera (Sicily). The whole area of the town was gridded with squares of 10x10 m to isolate functional areas and identify the most interesting zones for new archaeological samples. The survey was carried out in two fields (9400 m2), counting and recording all findings. Only diagnostic pottery and figured pottery, antefixes, loom weights, millstones and so on were collected. We can observe, analysing in detail our results for both fields, that functional areas could not be isolated, perhaps because the urban and social …

Urban Blight and Redevelopment: An Urban Participation Path

2018

This paper pays particular attention to one of the many participatory models present in the landscape of urban and territorial planning. Specifically, the ACTION PLANNING model was chosen; a model used in Anglo-Saxon countries to identify the problems and needs of the inhabitants of a given territory, through the involvement of interested parties or stakeholders. The model is applied in Sicily, to Villaseta, a small rural settlement, located southwest of the city of Agrigento, which consists primarily of affordable and social housing. It is a suburb without identity, left to itself, where – despite the valuable cultural, historic, scenic, and most importantly human resources – one notes the…

Pressure solution compaction of sodium chlorate and implications for pressure solution in NaCl

1999

Sodium chloride (NaCl) has been extensively used as a material to develop, test and improve pressure solution (PS) rock deformation models. However, unlike silicate and carbonate rocks, NaCl can deform plastically at very low stresses (0.5 MPa). This could mean that NaCl is less suitable for use as an analogue for rocks that do not deform plastically at conditions where PS is important. In order to test the reliability of NaCl as a rock analogue, we carried out a series of uniaxial compaction experiments on sodium chlorate (NaClO3) at room pressure and temperature (P‐T) conditions and applied effective stresses of 2.4 and 5.0 Mpa. NaClO3 is a very soluble, elastic‐brittle salt, that cannot …

New archaeological discoveries through magnetic gradiometry: The early Celtic settlement on Mont Lassois, France

2006

The burial complex of the “Lady of Vix” was discovered and excavated in the 1950s at the foot of Mont Lassois (Figure 1), a mountain situated close to the town of Chatillion-sur-Seine in the Bourgogne region of France. The assemblage of the burial goods was rather extraordinary, including such items as an artfully crafted golden necklace with winged horses and a voluminous wine-mixing vessel, probably made in a Greek workshop, capable of holding 1100 liters. According to archaeological research, this member of the aristocracy must have lived during the period between 550 and 500 BCE. Several large-scale geophysical research projects were undertaken in the vicinity of the burial complex duri…

Crust–mantle transition and Moho model for Iceland and surroundings from seismic, topography, and gravity data

2005

An increasing data set exists on the nature and thickness of the Iceland crust. This paper relates topography, i.e., elevation and bathymetry (TOP), Bouguer gravity anomalies (BA) and Moho depths to each other to assess the consequences of the “thick crust model” for Iceland in the context of the North Atlantic. Results of regression of TOP and BA vs. Moho depth are converted into “Airy densities” Δρ* (mantle crust density contrasts in the case of ideal Airy isostasy). For Iceland, Δρ* is very low (105±10 kg/m3); for the adjacent continental margins and relicts, it is high and intermediate for the Jan Mayen Ridge. The values are affected by lithosphere cooling and systematic variations of i…
