and a more accurate definition of the geomotry of the lithological bodies in the Firenze subsurface as well as better understanding of the recent geological evolution of the area. The recent geological history is primarily controlled by both the Apennine
Understanding the geometry of structures and relationships among stratigraphic and tectonic units at the depth is one of the main challenges faced by geologists. This aim is traditionally pursued through interpreting geological and geophysical data
in one or two dimensions and performing structural analysis. The aim of this prototype study is to define and test a methodology for building three-dimensional geological models based on maps on the scale of 1:50000, from the new Italian geological maping

The geology of the Rocca Busambra-Corleone region, in centralwestern Sicily, is relevant to the understanding of the central sector of the Maghrebian-Sicilian fold-and-thrust belt. In the investigated area Mesozoic shallow- and deep-water carbonate
Changes of the geological environment of the northern Black Sea region and the chemicalization of agricultural production
of water bodies, confined aquifers with pesticides and ground water with nitrates. Ideas on limitation of the harmful impact of agrochemicals upon the region's environment are presented here.

Geological features, technological characterization and weathering phenomena of the Miocene Bryozoan and Lithothamnion limestones (central-southern Italy)
Bryozoan and Lithothamnion limestones (BLL) from central-southern Italy, commercially known as Perlato Royal Coreno, were used for a long time in the monumental architecture of the Campania and Lazio regions. In this paper, new mineralogical
-petrographical and engineering geological data about BLL are reported and the relations between the lithofacial and technical features of this stone are investigated. Finally the main weathering phenomena affecting the stone were recognised through a detailed
Geomorphic observations of rivers in the Oregon Coast Range from a regional reconnaissance perspective
This paper presents the results of examining some aspects of river morphometry in Western Oregon to better understand the geologically recent history of Pacific-plate subduction. Changes in long profile, gradient, gradient index, pseudo-hypsometric
integral, valley incision, and sinuosity fractal dimension were studied. All data were gathered from topographic quadrangles and geologic maps, and so the results are limited to the description of river forms with only limited interpretations.
Cet article est un résumé de la thèse de doctorat de L'A., soutenue à l'université de Salford, Lancashire, Angleterre, et dans laquelle il étudie le rôle des influences géologiques sur le développement du paysage de la région de Bamenda Highlands.

This paper uses a time-dependent glaciological model to produce numerical reconstructions of the late Weichselian Svalbard-Barents Sea Ice Sheet, taking account of recent geological, biological, and chronostratigraphic evidence of climatic change
The theoretical and practical definition of the term periglacial in its geographical and geological meaning
the periglacial environment can be subdivided into regional types which again can be defined by climatic parameters. A map showing the extent and regional differentiation of the present polar periglacial zone, idealized schemes showing its delimitation

The geological mapping of the 438 Sheet «Bari» (scale 1:50.000), located in the northern part of the Murge area (Apulia, southern Italy), offered the opportunity to revise the local stratigraphy of the mid-Cretaceous carbonate succession belonging
to the Calcare di Bari Fm. In agreement with the previous edition of the Geologic Map of Italy few stratigraphic intervals showing a rich content in rudist assemblages and an interval of dolomitic breccias have been used as reference layers and successfully used
