Sedimentation close to the active Medlicott Wadia Thrust (Western Himalaya): how to estimate climatic base level changes and tectonics.

2017

16 pages; International audience; The Medlicott-Wadia Thrust (MWT) is one of the major active out-of-sequence thrusts in the Himalaya. Studies on Quaternary terraces in its vicinity have been performed using sedimentological, geomorphic and geochronological methods. We focus on the Riasi zone, south of the Pir Panjal range, in the Jammu and Kashmir region of India. The sedimentary units of Quaternary landforms have been mapped as a function of their location with respect to the thrust faults, their relative chronology, and their lithology. Three aggrading sedimentary units, five thin units above strath surfaces at the footwall of the fault system, and seven thin units above strath surfaces …

Roman Rhine settlement dynamics evidenced by coin distribution in a fluvial environment (Oedenburg, Upper Rhine, France).

2008

International audience; On the basis of archaeological and alluvial records, this paper presents the first spatial analysis of artefacts in relation to the evolution of the Rhine River, at the Gallo-Roman site of Oedenburg, during the first four centuries AD. The dataset consisted of several thousand Roman artefacts found by pedestrian prospecting over the last twenty years, over half of which were coins. This dataset was used together with high-resolution topography and geomagnetic mapping, to reconstruct settlement evolution, both on the terrace and in the floodplain. A comprehensive monetary chart has been compiled for the Oedenburg site, which highlights four major phases of settlement.…

Late Quaternary coastal uplift of southwestern Sicily, central Mediterranean sea

2021

Abstract Mapping and luminescence aging of raised marine terraces and aeolian ridges along an ∼90 km coastal stretch in southwestern Sicily provide the first quantitative assessment of vertical tectonic deformation in this region, which spans the frontal part of an active thrust belt. We recognized a staircase of eleven terraces and nine related aeolian ridges. The elevation profile of terraces parallel to the coast shows a >90 km long bell-shaped pattern, onto which shorter-wavelength (∼10 km long) undulations are superimposed. Luminescence ages from terraced beach deposits and aeolian sediments constrain the position of paleoshorelines formed during MIS 5e, 7a and 7c, with a maximum uplif…

The impact of an urban toll ring on housing prices

2020

Abstract Building on standard urban economics theory we set up a stylized model within which we demonstrate that the imposition of a toll ring leads to higher housing prices within the ring, and lower outside the ring. We examine this prediction empirically by using transaction data for 15,306 dwellings in the Norwegian town of Kristiansand, where since 1992 there has been a toll ring. We find that the toll ring implies 6.9 per cent higher housing prices within the toll ring than outside it. The relationship between toll fees and housing prices seems to be stable over time. The impact of the toll ring on the prices of detached houses, apartments, row houses and twin houses is strikingly dif…

The importance of terracing in the traditional cultural landscapes: the case study of Sicily (Italy)

2012

The landscapes formed by agricultural terraces are the natural result of the encounter between the characteristics of an environment and the creative force and genius of man, the slow evolution of this relationship between nature and culture, a collective project that balanced the need for producing with the resources available and the native character of the environment. These cultural processes produced a great variety of landscapes. However, they are not supported or confirmed by common inventories allowing to identify and classify the typical Main Traditional Landscape (MTL) within which very important is the role carried out by terraces and related man-made structures, both for natural…

On the generation and degradation of emerged coral reef terrace sequences: First cosmogenic 36Cl analysis at Cape Laundi, Sumba Island (Indonesia)

2021

(IF 4.45: Q1); International audience; The emerged coral reef terrace sequence at Cape Laundi, on the north coast of Sumba Island (Indonesia), with at least 18 successive strandlines, remains poorly dated in spite of numerous previous data. The age discrepancies within these coral reef terraces (CRTs) were previously explained by their polycyclic nature, triggered by marine erosion and reoccupation of old coral colonies by new ones. This study aims at highlighting these processes, as well as the continental denudation that participates in the partial stripping of the thin superficial coral reef layer overlying the pre-existing surface, exhuming older coral colonies. For this purpose, we use…

Environmental features and land use of Etna (Sicily — Italy)

2007

Etna is the greatest volcano in Europe and one of the most active in the world. It is a complex strata-volcano formed of lava flows alternating with pyroclastic materials emitted over various eruptive areas which have, over centuries, built up the actual volcano. The climate in the Etna area is basically Mediterranean but rainfall and temperatures are affected by height, exposure of slopes, by winds and by clouds coming from the coast. Temperature distribution is uniform but rainfall is irregular. Moist winds from the sea bring rain to the eastern slopes. Surveys on the pedoclimate show an udometric regime ranging, according to altitude, from xeric to udic and a thermometric regime ranging …

El secano mejorado y la agricultura aterrazada. Paisajes significativos con un gran valor socio-ambiental y didáctico

2019

En los últimos veinte años, en las denominadas sociedades postproductivistas se ha producido un redescubrimiento del paisaje asociado a su identificación como un elemento identitario y de calidad. En la provincia de Alicante, representativos resultan el denominado secano mejorado (aprovechamiento de turbias) característico de la comarca de l’Alacantí y los paisajes aterrazados (Montaña de Alicante). Los objetivos de esta investigación son: 1) Analizar la ordenación tradicional de los paisajes derivados del uso de turbias y los aterrazados; 2) Analizar las estrategias de adaptación al medio y cómo el proceso de abandono ha repercutido ambientalmente en el área de estudio; 3) Poner de manifie…
