- PublicationOpen AccessThe glacial traces in the «parco Nazionale d 'A bruzzo » area (Central Apennines): Preliminary note(1990)
; ; ; ; ; ; ; ; ; ; ;In the mountainous area of the «Parco Nazionale d' Abruzzo », characterized by several massifs with maximum altitudes frequently above the 2 000 m, a large number of glacial traces can be observed. The examination of new evidence discovered and the re -examination of those already known has permitted to reconstruct several distinct glacial events. In the studied area the cirques are the most frequent forms due to glacial modelling, even though other glacial remains like troughs and moraine deposits are found in association with them. In a number of places the existence of several episods of glaciation is provided by the occurence of a cirque stairway observed on the same slope. Starting from the more complete and best preserved local sequence an attempt was made to put into order all the other glacial traces. Correlations have been based on relative position and morphology of the cirques and the snow limits. As a result, it seemed likely to refer the observed evidence to four distinct events of glaciation. The first glacial event (pre -wiirmian glaciation, probably Riss) is characterized by a snow limit situated about 1 340 meters a.s.l, and evidenced by few glacial forms in the massifs of Toppe del Tesoro, S. Nicola and the Meta Mountains. They consist of large badly preserved cirque-like depressions situated about 1 300-1 400 meters a.s.l., and moraine deposits whose position and distribution largely contrasts with the actual orographic configuration. During a new glacial advance (maximum wiirrnian expansion) the snow limit rised to 1 560 m. Numerous are the traces relative to this ad vance, consisting in a large number of erosional forms , like cirques and glacial troughs, and morainic deposits which frequently preserve their ori ginal morphology forming lateral and frontal moraines. The third event (first late Wiirmian stage = first apenninic stage of FEDERICI, 1979) is characterized by a further rise of the snow limit now situated about 1 760 m. The evidences rel ative to this minor expansion consist only of erosional forms except one morainic deposit rico gnized on the eastern side of the Meta Mountains. Effects relative to the fourth event (second late Wiirmian stage = second apenninic sta ge of FEDERICI, 1979) can be observed only in the reliefs situated North of the Sangro Valley and in the Meta Mountains, while in the other reliefs the snow limit, situated about 1 970 m, had already reached or passed the altitude of their highest peaks. A summary examination of the distribution and the morphological features of the glacial traces studied shows that the area South of the Sangro valley seems to have developed greater glaciers that the part of the studied area situated at the North of the same valley.82 228 - PublicationRestrictedStratigrafia ed assetto geometrico dell’Unità del Sannio nel settore settentrionale dei monti del Matese(2010-12-15)

Structural analysis and the chronostratigraphic redefinition of siliciclastic deposits covering the Sannio Unit and the carbonate platform successions of the Matese- Frosolone Units, indicate two main evolutionary stages in the Miocene- Pliocene structuring of this portion of the Southern Apennines. In the first stage, starting before Serravallian times, E-verging contraction affected exclusively the basinal units together with their siliciclastic cover. During the second stage, beginning after early Messinian times, NE-verging compression involved both the basinal Sannio Unit and the Matese-Frosolone Units.339 72 - PublicationRestrictedFirst assessment of the local seismic amplification susceptibility of the Isernia Province (Molise Region, Southern Italy) by the integration of geological and geomorphological studies related to the first level seismic microzonation project(2018-02-09)
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; This paper presents the results of the geological and geomorphological investigation carried out during the first level seismic microzonation project in the Isernia Province territory. The study area falls in one of the most seismically active areas of the Apennine chain and it has been struck, in historical times, by destructive earthquakes that caused several causalities and diffuse damages to the buildings. The analysis points out the occurrence of geological features that can determine possible site amplification phenomena related to areas with extensive outcrops of thick continental deposits or to unstable areas (both covering about 48% of the investigated areas). The latter are sometimes combined with geomorphological features such as scarps, isolated peaks, and ridges that are also responsible for possible site amplification. In addition, a susceptibility to local seismic amplification index has been introduced which highlights that more than 64% of the investigated area, along with a significant percentage of buildings, fall within the highest categories of susceptibility to local seismic amplification.161 7
