Paleogeomorphologic significance of redeposited dolomite in the Transdanubian Mountains in Environmental and dynamic geomorphology.
The Triassic dolomite, considered so far a uniform base, is found to be reworked in many places and vertically divided by several types of bauxite and red clay horizons. (DLO).
Rencontre de terrain dans les Préalpes de Vénétie et les Dolomites
Description et principaux problèmes de trois secteurs karstiques de l'Italie du NE : Montello et Plateau du Cansiglio en Vénétie, haut plateau de Sennes dans les Dolomites, où les lapiés sont particulièrement originaux. - (AW)
The glaciers of Mount Antelao (Dolomites, Italy) since the Little Ice Age
The study has estimated the reduction of the glaciers of Mt Antelao (Dolomites, Italy) from the Little Ice Age (LIA) to today using bibliographic and morphological data as well as modern techniques of data elaboration and processing. - (NF)
Explanatory notes of the Geomorphological map of the Alta Badia valley (Dolomites, Italy)
This paper shows the geomorphological aspects of the Alta Badia valley (Autonomous Province of Bolzano, northern Italy), located in one of the best known areas of the Italian Dolomites, between the passes of Gardena, Campolongo and Valparola
-Falzarego. The paper is also aiming at illustrating the annexed Geomorphological map of the Alta Badia valley (Dolomites, Italy), at 1:20,000 scale. - (NF)
The geomorphology of the Dolomites from a geomorphodiversity viewpoint
The Dolomites make up an important geo-heritage that can be considered as a high-altitude field laboratory for research and development of geomorphological theories and understanding. The A. stresses that on June 26th 2009 the Dolomites were
Les AA. combinent plusieurs approches géomorphologiques, géomorphométriques et géophysiques pour quantifier l'érosion sédimentaire de la vallée de la Vallunga dans le massif des Dolomites (Italie du Nord).
Glaciokarst assemblages, rarely documented in the United States are well represented in the Door Peninsula, where characteristic steps, pavements and enclosed depressions are developed in the Silurian Niagara Dolomite.
Soils from limestone and dolomite in the central Algarve (Portugal), their qualities in respect to groundwater recharge, runoff, erodibility and present erosion in Arid and semi-arid environments. Geomorphological and pedological aspects.
The purpose of this paper is to explain physical properties of soils derived from limestones, marls and dolomites and their qualities with respect to the water budget as well as the present soil loss of the selected area.
The use of landslide units in geomorphological mapping : an example in the Italian Dolomites
method has been applied to the area of Cortina d'Ampezzo (Italian Dolomites) where more than 30 landslides have been identified and grouped in 12 landslide units. The results are discussed.

This paper reports the findings of a ten-year study of potential weathering of machine-polished dolomite, granite and limestone discs buried in shallow pits beneath a variety of vegetation cover types in Kärkevagge and on an adjoining ridge
in Swedish Lapland. In general, dolomite was the most useful material for monitoring mass loss, with limestone weathering tending to be too rapid and granite weathering being too slow.
A debris flow event occurred in June 1997 in the Dolomites (Eastern Alps, Italy). The phenomenon was directly observed in the field and recorded by a video camera near its initiation area. The flow was triggered by a short duration, high-intensity
An investigation of water and ice chemistry in a fast-retreating glacier in the Dolomites (NE Italy) : the Fradusta glacier
Fradusta glacier (Pale di San Martino massif), the second largest icefield in Italian Dolomites, is evidencing a fast retreat, with a surface area reduction of about 90% in the last 100 years, and a negative variation of glacier front of 115.5 m
interactions between melting waters and the Dolomitic bedrock. The presence of ammonium ion in snow and ice samples is indicative of long-range global anthropogenic impact, which might be related to red snow events. Ammonium had a particular significance

Le Parc naturel des Dolomites Frioulanes, un grand théâtre naturel voué à la querelle entre l'homme et la nature
Près du Parc des Dolomites Bellunesi se trouve le territoire protégé d'une réserve naturelle, exceptionnelle par son étendue et par l'intérêt qu'il présente, bien que peu connu : le Parc des Dolomites Frioulanes. L'A. nous propose un aperçu
