We illustrate the results of geomorphological, stratigraphical and sedimentological analysis of the Tarija-Padcaya basin, a wide depression in the eastern side of the Bolivian Cordillera. The basin is well known for the rich mammal fauna discovered since the beginning of the 19th century. The sedimentary infilling belongs to the Tolomosa Formation, corresponding to a major synthem subdivided into three main sub-synthems, mostly made of fluvial and alluvial fan sediments locally weathered by paleoalfisols (Ancon Grande sub-synthem), glacial and fluvio-glacial sediments (Puente Phayo sub-synthem) and finally alluvial fan and alluvial plain sediments (San Jacinto sub-synthem). Radiocarbon dating provides a chronology for the last sub-synthem and testifies that the sequence encompasses the Last Interglacial-Glacial cycle and constitutes a good proxy record for Late Pleistocene climatic changes. The occurrence of glacial deposits in the deeper part of the sedimentary filling suggests a major ice advance during MIS 4 and, together with glacial geomorphological evidence, points to further glacial erosion during the Last Glacial Maximum (LGM). The importance of glacial deposition and erosion opens the question of correlation with the events reported in the nearby Altiplano, where glacial deposits have been recognized only along the slopes of the higher volcanoes. In the Altiplano the LGM has been claimed to be characterized by an absence of deposition or deep erosion, due to extreme dryness, but the Tarija record suggests an erosional event of a scale that would imply the occurrence of a large ice cap. © 2010 The Geologists' Association.

The Sama Range (Tarija Department, Bolivia) boasts a characteristic Andean landscape of high environmental, archaeological and architectural value that is home to the Sama Range Biological Reserve, where the Tajzara plain, with its large lagoons, is one of its outstanding features. The research conducted has studied the built habitat, identifying the domestic and religious architectural models present in order to propose protection policies and preservation strategies along two lines of work: The preservation of isolated settlements on the one hand, supporting local productive activities, and the promotion of experience tourism on the other, implementing lodging in traditional rehabilitated buildings. © 2015 Taylor & Francis Group.
