In recent years, the application of archeometric studies has increased notably. On the one hand, because it has managed to expand an interdisciplinary field that has allowed the training of professionals. On the other hand, because work spaces have been developed with access to the use of different analytical techniques, as well as dialogue and exchange in the analysis of the results between specialists. Regarding the study of archaeological ceramic materials, advances in the development of techniques and technology related to archaeological work has facilitated the review of results and data that were obtained in a timely manner during the investigations, in order to continue exploring archaeological problems and solve pending issues related to processes of production and circulation of ceramic materials, social practices of exchange, interaction and integration and their associated rituals, among others. This work aims to present the application of new technologies and methodologies adapted to ceramic materials to evaluate their potential related to the scope of the information obtained and to review and incorporate new data related to the study of the origin of raw materials, characterization of pastes and techniques of manufacturing used by Andean potters. For this, two case studies of archaeological ceramics from the Quebrada de Humahuaca, Jujuy province (Argentina), are presented, based on analyzes carried out with petrography-QEMSCAN, Raman-IFT-IR, UV-IR microscope and pigment microstratrigraphy. The results obtained have offered additional and specific information to interpret the interactions inside and outside the space of the Quebrada de Humahuaca in different chronological moments of the pre-Hispanic past, giving an account of the use of the circumpuneño space by the communities that inhabited it

This work shows the results obtained from the vegetable microremains analyzes (phytoliths, and starches.) carried out on ceramic and lithic artifacts, from the archaeological sites Los Varela Recinto 11 and El Polear 1, located in the Ambato Valley, Catamarca, Argentina. Although this type of study has been carried out systematically in different regions of the Argentine Northwest, the truth is that most have focused mainly on grinding instruments, with fewer analyzes on ceramic material. In total, 27 samples (21 ceramic fragments and 6 lithic artifacts) were examined, with the main objective of establishing a possible relationship between ceramic classes, vessel shapes and their use. The results obtained allowed the identification of remains of maize (Zea mays) and carob (Prosopis sp.) in ceramic material and maize in lithic. Although this work is preliminary, the information obtained, integrated with results derived from previous investigations, allow us to propose, at least for the moment, that maize played a central role in Aguada of Ambato during the first millennium of our era.

A synthesis of the advances in pottery research of the Meliquina Archaeological Site (LAM) is presented, in a wooded and lacustrine environment in the southern sector of the province of Neuquén, Argentina. The analysis strategy was not based on typological studies that used the potential capacities and limitations for formal aspects, but on the description of results of different archeometric analyzes from a multiroxi approach, organized in provenance, structural and functional studies. Among the provenance studies, we identified immediately available clays and another non-local chemical group by TXRF. Regarding structural studies, we observed manufacturing by superimposition and spiral elevation of rolls using radiographic images. Regarding functional studies, by Gas Chromatography we identified fatty acids from leaves, berries and seeds among the adhered residues, together with negative imprints analyzed by means of Electronic Scanning Microscopy identified with Bromus sp. and other domesticated non-local species such as corn from phytoliths and starches. The activation, cultivation and molecular identification of cryotolerant fermentative yeasts, together with phytoliths and thermo-altered starches from corn kernels suggest that, like other seeds and fruits, they may be part of the processing or containment of fermented beverages.

Cultural heritage biodeterioration is an actual research line that it has been poorly studied from an archaeological perspective. However, current archaeometric investigations in pottery materials point to a diversity of biological agents involved in a complex mechanical, chemical and fouling deterioration process of the external and inner surfaces and the paste, presenting a sinergetic relationship in situ by weathering, erosion and postdepositacional agents in archaeological pottery materials from Northern La Rioja province, Argentina. Physical and chemical properties of these materials make them bioreceptive for microbiological colonization in environments with a strong aridity. Besides, these species impact for pottery materials preservation and for investigators health care was recognized. The aim of this work is to discuss and reflect about microbiological colonization implications in the archaeological pottery materials studied. Potential bias in archaeometric sample preparation and data collection is pondered and, these agents contribution as a complementary evidence lines in archaeological sites formation process, paleoenvironment and objects and/or raw materials circulation is enlighten.

Familia Primón (FP) is an archaeological site located in a residential area in the south of Coronda city, on theright bank of the homonymous river (San Jerónimo department, Santa Fe province). During the archaeological fields works carried out, three sectors were excavated; sector 1 corresponds to a multiple human burial area. This paper presents the results of the reconstruction of the burial map ―achieved from the digitalization of the spreadsheets and photographs recovery in analogical format and their management through geographic information systems (GIS)― and from anatomical, quantitative and taphonomic studies carried out on the human bone remains. Additionally, a synthesis of available information of other sites with human burials located in the area of the Coronda River is made. In general, the results show that at least 18individuals were buried at the FP site, both in primary and secondary burials, with different orientations and characteristics comparable to those relieved from other archaeological sites in the area and also in the Northeastern of Argentina.

Radiocarbon dates obtained from organic residues deposited on the walls of five sherds recovered at three archaeological sites are presented here. The sites are located in the North Patagonian forest (Chubut and Río Negro Provinces). These dates are the first obtained in a forest environment and cover the period between 960 ± 22 and 328 ± 31 years BP. Besides, these results allowed us to discuss issues related to the integrity and resolution of archaeological deposits, clarifying previsouly raised questions about site formation processes

This essay raises somequestions about the reference of rock art and its epistemic model. It confers on it important heuristic content and examines it in relation to the lacanian approach to signifiers. He tries to approach the phenomenology of this art with analytical instruments that he estimates can not be left out even in the face of such elusive manifestations as rock art. 

Zooarchaeology, understood as the study of the relationships that animals have had with human populations of the past and about the multiplicity of roles they have fulfilled in human cultural systems, is a discipline that has experienced great national and international development in recent decades. The use of methods of anatomical and taxonomic quantification, and new methodologies and techniques such as isotopic and molecular analysis, has provided new perspectives for zooarchaeological research. However, we believe that the information these methodologies produce, and zooarchaeology in general, are often not adequately represented in museum institutions. These institutions mediate the link between society and its past through the construction of an institutional narrative that accompanies the archaeological collections on display. Here we research different museums of the Province of Buenos Aires and consider that the zooarchaeological record exhibition is usually subordinated to other archaeological collections (i.e. ceramics, lithic instruments), receiving a peripheral place within the institutional discourse. Therefore, we explore the diverse information that zooarchaeological samples can offer and generate proposals for their dissemination, emphasizing the importance of the protection and conservation of this heritage.

At the National University of Education (UNAE), pre-professional practices play a determining role in the training of future initial education teachers. Faced with the Covid-19 pandemic, they have become virtual where photography becomes a fundamental didactic resource, not only in the collection of evidence but also as part of the teaching reflection, that allows conceiving education in the new reality where students of different levels have to adapt. With the support of the FlipSnack tool, the information collected is visualized and analyzed. In such a way, that the practitioners have acquired new skills with the help of the TIC and TAC in the activities proposed with a specific didactics required in synchronous classes with children and families. Thus, the photographic image constitutes a significant contribution to the task, as it strengthens the feedback of the teaching-learning process.
