Bodegas, lagares y almazaras en el territorio de Kelin (siglos V-III a. C.): el caso de la Rambla de la Alcantarilla (Requena, Valencia)
2016
Archaeological evidences date the expansion of grape vineyards in the territory of the Iberian Iron Age city of Kelin from the 5th to 3rd centuries BC; although the origins are documented in the 7th BC. One of the singularities of this territory is the existence of outdoors stone structures for the production of wine and oil. All are located in a specific area of the territory (la Alcantarilla and Los Morenos ravines) (Requena, Valencia), and are associated with archaeological materials that allow date them as Iberian. In this paper we approach the rural settlement pattern in la Alcantarilla ravine and we present in detail the archaeological sites of Rambla de la Alcantarilla and Solana de …
A multiproxy record of palaeoenvironmental conditions at the Middle Palaeolithic site of Abric del Pastor (Eastern Iberia)
2019
This paper presents a multiproxy palaeoenvironmental study from Abric del Pastor (Alcoy, Spain), a rock shelter which has yielded evidence for Middle Palaeolithic human occupation. The sedimentary sequence has been analysed for lipid biomarker n-alkane abundances (ACL, CPI), compound specific leaf wax δH and δC, and bulk organic geochemistry (TOC, %N, %S), providing a record of past climate and local vegetation dynamics. Site formation processes have been reconstructed through the application of soil micromorphology. Analyses of anthracological, microvertebrate and macrofaunal assemblages from selected subunits are also presented here. Our data indicates that a variable climate marked by pr…
Human induced soil erosion and gully system development in the Late Holocene and future perspectives on landscape evolution: The Myjava Hill Land, Sl…
2013
In humid climate zones, like Central Europe, past soil erosion and gullying are strongly connected with agricultural expansion, and extreme soil erosion events often play an important role in land abandonment. This paper provides a case study to demonstrate the interaction between land use, soil erosion, floodplain development, and land use changes in a 0-order catchment in the Babikovce catchment, Myjava Hill Land, situated in western Slovakia. Sedimentological, pedological, geoarchaeological and historical data indicate two main periods of intensive hillslope erosion and gullying since the High Middle Ages. In particular, a few extreme precipitation events (or rapid snowmelts) caused inte…
Similarity between morphological characteristics of rills and ephemeral gullies in Sicily, Italy
2009
This paper reports the results of a field investigation aimed to establish morphological similarity between rills and ephemeral gullies. Rill measurements were made on 14 plots having a surface area of 22–352 m2 located on a 14·9% slope and on a plot 6·0 m wide and 22·0 m long having a uniform 22·0% slope. The plots are located on the experimental station for soil erosion measurements, ‘Sparacia’, of the Agricultural Faculty of Palermo University, in Sicily, Italy. All plots are subjected to natural rainfall. The measurements were made immediately following five events between November 2004 and December 2005. The ephemeral gully measurements were made on a cultivated area of about 120 ha, l…
Mio-Pliocene rodent assemblages from Alcoi Forn (Alcoy Basin, Eastern Spain). Biostratigraphical and palaeoclimatical inferences
2015
AbstractIn this work, we describe four new micromammal sites in the northern side of the Gormaget ravine, in the Alcoy Basin (Spain): AF-1’06, AF-1’07, AF-1A and AF-2. Based on the study of the faunal remains from these localities, we infer a latest Turolian-earliest Ruscinian age for AF-1’06 and AF-1A, and an earliest Ruscinian age for AF-1’07 and AF-2. The species assemblage of the locality AF-1’06, the only one which have yielded a sufficient number of remains to perform a palaecological analysis, shows warm and dry conditions near the Mio-Pliocene boundary in the Alcoy Basin. These data show a reduction of dry and warm indicators from older to younger localities in the Alcoy Basin, sugg…
Du fouillis végétal à l'espace gazonné : structure et typologie des jardins réunionnais de la Ravine des Cabris
2014
International audience; S’intéresser aux jardins de l’île de la Réunion ne procède pas uniquement d’un attrait naturaliste ou esthétique car les jardins sont aussi des espaces de vie qui ont été au centre des préoccupations lors de l’épidémie de chikungunya qui a sévit sur l’île de 2005 à 2006. Les politiques de prévention ont mis l’accent sur le risque que constituait le jardin et il a été rapidement demandé à la population de devenir acteur en agissantsur son environnement et en éliminant les sources potentielles de gîtes. Dans le cadre d'un projet de recherches ANR SEST (2006-2009) « Anthropo-MTV » sur la gestion de l’épidémie de chikungunya les auteurs ont mené une enquête sur les jardi…
Erosion and stabilisation sequences in relation to base level changes in the El Cautivo badlands, SE Spain
2008
Abstract The complex multiple-age badlands at El Cautivo are cut in upper Miocene marls of the uplifted and dissected Tabernas Basin, Almeria, in semi-arid SE Spain. Previous work identified six episodes of erosion and subsequent stabilisation, with ages ranging from the late Pleistocene to the present day. This paper uses newly-acquired digital elevation models, orthorectified aerial photographs, and field survey data to illustrate the development sequence of a series of gullies which drain into the Rambla de Tabernas. Changing drainage directions and phases of incision and stabilisation are related to the filling and subsequent dissection of the Tabernas lower lake sediments, differential…
New rodent faunas from Middle Miocene and Mio- Pliocene in the Cabriel Basin (Valencia, Spain)
2011
Five new localities with micromammal remains have been located in the Cabriel Basin. These localities are situated in the eastern area of the Cabriel Basin, in the Juan Vich ravine, where the oldest deposits of this basin crop out. The localities JV2, JV3 and JV6 are of Middle Miocene age, JVTLI1 of Middle Miocene or Late Miocene age and JVTS1 of Late Miocene or Early Pliocene age. The beginning of the sedimentary history of the basin was attributed to Late Turolian (Late Miocene). The new sedimentary record from the Juan Vich ravine and the mammalian findings extend the stratigraphic and paleontological knowledge of the Basin.
