“…The interpretation of the isotope composition of Quaternary mollusk shells from the area, based on the modern results obtained here, coincides with previous explanations carried out on the basis of paleoecological and sedimentological studies (De Francesco et al, 2007;De Francesco & Hassan, 2009) bringing additional support to the validity of isotope data for paleoenvironmental and paleoclimatic inferences. This work suggests that isotope composition of freshwater mollusk shells brings valuable information for discussing past changes in large-scale atmospheric circulation patterns during the Late Pleistocene and the Holocene.…”

“…O enriched meteoric precipitation. This is based on their 14 C ages, which fall between 34 and 31 ka, and clearly prove this series was deposited during an interstadial (Marine isotope stage 3) of the last glacial cycle with wetter and warmer climatic conditions than the present time (De Francesco et al, 2007;Tripaldi et al, 2011). In such scenery, water bodies would have been subjected to intense evaporation.…”

“…The LB succession (33°28′S, 69°03'W), which records the interval between circa 35 14 C ka BP and 31 14 C ka BP (Table 2), crops out on the right margin of Arroyo La Estacada, a tributary of Río Tunuyán (in the area of modern sites 1-6; Figure 1). The succession, which is 3 m high, was analyzed in detail by De Francesco et al (2007). In that article, the δ The PV, LG and PM successions, which testimony the Late Glacial, early Holocene and Late Holocene, respectively (Table 2) 14 C years BP) and Heleobia kuesteri from that level were analyzed here.…”

ABSTR ACT -The variability in δ 18O and δ 13 C composition of modern and fossil mollusk shells in central-western Argentina was assessed in order to contribute to a better understanding of their value as paleoclimatic indicators. Living mollusks were collected from 17 sites distributed along a latitudinal/altitudinal gradient in Mendoza Province. Quaternary mollusks were obtained from fi ve alluvial successions outcropping in river margins from the same area. C, foi registrado durante o Holoceno, sugerindo a existência de paleoambientes menos produtivos, provavelmente devido à incidência de condições mais secas do que no presente.Palavras-chave: isótopos de oxigênio e carbono, semi-árido, reconstrução paleoambiental, América do Sul, Quaternário Superior, piemonte andino.

-HOLOCENE CONTINENTAL MOLLUSCAN FAUNA (PAMPEAN REGION, ARGENTINA). In this study the molluscan fauna recovered from six archaeological sites of the Interserrana Bonaerense area is analyzed. Three geographical sectors were studied in this area: I) Middle river basin of Quequén Grande river; II) Southwest of the Interserrana area, and III) Upper river basin of the Tapalqué stream. The systematic review of the continental mollusks recovered was complemented with quantitative, stratigraphical and chronological data for each site since the early Holocene until the present. Additionally, ecological requirements and modern distribution patterns of the taxa recorded were considered in order to search for eventual palaeoenvironmental variations in space and time. A total of 15 taxa (14 Gastropoda and one Bivalvia) were identifi ed in the Luján Formation deposits from southeastern Buenos Aires Province. The fi rst Holocene records for "Aplexa" minor (d'Orbigny), Drepanotrema kermatoides (d'Orbigny), Antillorbis nordestensis (Lucena), Omalonyx unguis d'Orbigny and Pisidium sp. are reported in the Bonaerese Interserrana area. Overall, the mollusks suggest palustrine habitats at the beginning of the early Holocene. During the middle Holocene, they suggest higher humidity (increase of the precipitation pattern) ca. 4.9 kyrs BP and ca. 4.7 kyrs BP. At the beginning of the late Holocene they indicate a general arid trend interrupted by brief humid episodes registered ca. 2.5 kyrs BP and ca. 2.2 kyrs BP. The integration and correlation of molluscan records in spatial and temporal scales allowed recognizing geographical displacements (i.e. Retidiscus reticulatus Fonseca & Thomé) which represent biotic responses to Holocene climate variations as well as local environmental differences for stratigraphical sequences of similar chronologies.Key words: continental mollusks, contexts of depositation, paleoenvironments, Late Quaternary, Interserrana Bonaerense area, Luján Formation. RESUMO -No presente estudo é analisada a malacofauna proveniente de seis sítios arqueológicos da área Interserrana Bonaerense. Foram estudados três setores geográfi cos desta área: I) bacia média do río Quequén Grande; II) sudoeste da área Interserrana e III) bacia superior do arroio Tapalqué. A revisão sistemática dos moluscos continentais recuperados foi complementada com dados quantitativos, estratigráfi cos e cronológicos de cada sítio desde o Holoceno inicial até a atualidade. Adicionalmente, foram considerados os requerimentos ecológicos e os padrões de distribuição moderna dos táxons a fi m de inferir eventuais variações paleoambientais. Um total de 15 táxons (14 Gastropoda e um Bivalvia) foram identifi cados nos depósitos da Formação Luján do sudeste da Província de Buenos Aires.
