Abstract: Is has been carried out a palynological study of a core obtained from a deposit located in the high basin of Guadiana river (Southern Iberian Meseta). The dynamics of the vegetation from the pollen diagram and its correlation with other sequences from the mediterranean region has allowed to distinguish the climatic phases that have occurred during the last 10,400 years BP. The evolutionary trend has been as follows: a continental climate cold and arid in the lower part of the pollen sequence; in the middle part, between 8,500 and 5,800 years BP, a warm and humid climate and finally, from 4,500 years BP, the beginning of a continental mediterranean climate. Also, three arid phases have been observed: between 9,100-8,500 years BP, between 5,800-4,500 years BPand between 2,500-2,000 years BP.

Palaeoenvironmental significance of palustrine carbonates and calcretes in the geological record
TL;DR: In this paper, the authors studied the transition from one form to another, revealing the interplay between pedogenic, sedimentary, and diagenetic processes, and three main factors control the formation of these carbonates: the position of the water table, the host rock, and the period of sub-aerial exposure.

Vegetation changes and hydrological fluctuations in the Central Ebro Basin (NE Spain) since the Late Glacial period: Saline lake records
Penélope González-Sampériz,Blas L. Valero-Garcés,Ana Moreno,Mario Morellón,Ana Navas,J. Machín,Antonio Delgado-Huertas +6 more
TL;DR: In this article, the main features of the palaeoclimate evolution during the last glacial cycle were reconstructed from ephemeral saline lakes in the Central Ebro Basin, together with a detailed review of the main saline records.
Palaeoenvironmental reconstruction of Northern Spain during the last 8000 cal yr BP based on the biomarker content of the Roñanzas peat bog (Asturias)
TL;DR: In this article, the authors determined the lipid distributions (n -alkanes, n -methyl ketones, n-alkanoic acids, 5- n -alkyl resorcinols and sterols) and total organic carbon (TOC) content in a 2.0m deep Sphagnum-dominated ombrotrophic peat bog in Northern Spain.

Late holocene environments in Las Tablas de Daimiel (south central Iberian peninsula, Spain)
María José Gil García,María Blanca Ruiz Zapata,Juan I. Santisteban,Rosa Mediavilla,Enrique López-Pamo,Cristino J. Dabrio +5 more
TL;DR: In this paper, the use of a high resolution pollen record in combination with geochemical data from sediments composed mainly of layers of charophytes alternating with layers of vegetal remains plus some detrital beds allowed the reconstruction of the environmental evolution of the last 3000 years in an inland wetland of the Mediterranean domain, thus introducing a new climatic dataset for the Late Holocene.
Climatic changes since the Late-glacial/Holocene transition in La Mancha Plain (South-central Iberian Peninsula, Spain) and their incidence on Las Tablas de Daimiel marshlands
Miriam Dorado Valiño,Ana Valdeolmillos Rodríguez,M. Blanca Ruiz Zapata,M. José Gil García,Irene de Bustamante Gutiérrez +4 more
TL;DR: A palynological and lithological continuous record from La Mancha Plain (South-central Iberian Peninsula, Spain) is presented in this article, which allows the reconstruction of the climatic evolution in the area since the Late-glacial/Holocene transition.

Climatic Change on the Iberian Peninsula Recorded in a 30,000-Yr Pollen Record from Lake Banyoles
Ramon Pérez-Obiol,Ramon Julià +1 more
TL;DR: The Banyoles lacustrine sequence shows that the vegetational history of the northeastern Iberian Peninsula during the last 30,000 yr follows the North Atlantic pattern of climatic oscillations as mentioned in this paper.

Palynological Evidence for Climatic Change and Human Activity during the Holocene on Minorca (Balearic Islands)
TL;DR: In this article, four pollen diagrams from Minorca (Balearic Islands) were correlated with other previously studied sequences from Majorca and Minorca to define a Holocene landscape sequence for the region from 8000 yr B.P. to the present.

Geomorphology and late Holocene climatic change in Northeastern Spain
TL;DR: In this article, the accumulation and downcutting stages affected the slopes and infilled valleys in the semiarid areas in NE Spain during the late Holocene, and the authors used archaeological remains, charcoal and ashes within slope deposits and valley fills to carry out accurate data.
