Classification, Typology and Distribution of Solification Rocks in Romania

Abstract: The present paper seeks to contribute to the better knowledge of the parental rocks of different soil types that are found in Romania, as well as their share in the country’s territory.
During its geological-geographical evolution, on Romania’s territory various geological (petrographic) formations have been formed, from crystalline rocks to loams, sands, fluvial and organic deposits. Because the types of rocks are numerous and their territorial distribution changes in narrower areas, the paper aims to group them according to their associating mode, genesis, as well as to their contribution to soil formation.
The paper introduces a new map of solification rocks in Romania, scale 1:1.000.000, which aims not only to their theoretical classification, but also to determine the surfaces occupied by each category, and their distribution on the country’s major relief units. In addition to the new map, achieved after the processing and updating of different cartographical materials using GIS techniques, information regarding the soil types formed on each category of parental rocks is provided.

Indicators of the Human Pressure on the Environment in the Bălăciţa Piedmont

Abstract: The Bălăciţa Piedmont represents the western subdivision of the Getic Piedmont, being located in south-western Romania. The unit under study is an early inhabited space and, at the same time, an area of active development of numerous geodynamic phenomena. The man-induced changes had significant influences upon the environment and especially upon the relief, the increased vulnerability of the terrains to the dangerous geomorphologic phenomena being one of the most important problems that the local communities have to face nowadays. The present study aims to assess the human influence upon the emergence of environmental unbalances and especially the human actions that influence the risk geomorphologic processes. A relevant means in the process of evaluating the type and dimension of the human intervention within a given territorial unit concerns the computation of certain synthetic indicators that characterize the degree of landscape transformation. The assessment has been realized through the analysis of statistical data at the level of the administrative-territorial units that overlap the Bălăciţa Piedmont. The general research regards an interval of thirty years (1977 – 2007), while the focus was laid upon the transition period (1992, 2002, and 2007).
