Weathering Processes on Sandstone Painting and Carving Surfaces at Prehistoric Rock Sites in Southern Spain

چکیده
The sandstones which constitute the host rock for prehistoric artwork in Rock Groups of Tajo de las Figuras and Peñas Cabrera (southern Spain) show a serious degree alteration, due both to natural processes those related anthropogenic animal activity. A detailed study was carried out on petrological compositional characteristics (fresh altered rock) groups, geological climatological area they are located. have very similar areas. This likeness causes nature weathering be areas studied. These can divided terms predominant mechanisms alteration into three inter-related categories: mechanical weathering, chemical bio-induced processes. However, different climatic conditions two located directly influences intensity these precipitation range temperature variation with heavy winter frosts El significantly higher than Cabrera; this translates rate at Figuras. Regarding action, types influence deterioration distinguished: direct one, consists scouring wetting walls order increase chromatic contrast; an indirect is extraction blocks sandstone upper part shelters, turn encourages development

Over the past few years, due to the advances in laser scanning techniques, 3D modeling software, computer power and virtual reality, many cultural heritage applications require 3D modeling and realistic visualization of the heritage models for various purposes. In such a project to virtualize the Dazu Rock Carvings, we proposed a commercially available solution. In this paper, we present this s...
متن کاملTechniques for Measuring Rock Weathering: Application to a Dated Fan Segment Sequence in Southern Tunisia
There are a number of techniques for estimating the amount of weathering a clast has undergone. These usually have the objective of establishing an ordinal chronology of geomorphological surfaces, or investigation of site-specific conditions affecting weathering rates. Three such techniques are applied to a dated sequence of alluvial fan segments in southern Tunisia. Two of these techniques dep...
