No full textLa Flecha Formation (Upper Cambrian) in Precordillera Central is composed of microbiolitic buildups, with a shallowing upward tendency. This paper includes the study of mega, meso and microstructure of thrombolites and stromatolites and the microfacial analysis of the muddy sequence. The following microbiolitic facies were recognized: F1: stratiform and domal stroms, with low synoptic relief, F2: stratiform thrombolites, F3: stratiform-domal thrombolites with low synoptic relief, F4: inverted cone-shaped thrombolites and F5: domal thrombolites. The associated muddy microfacies are represented by: MF6: mudstone with microbial lamination and fenestral fabric, MF7: mudstone with grumous microestructure, MF8: bioturbed mudstone and MF9: floatstone, related to storms. The depositional model of this sequence was interpreted as a carbonatic platform with a complex of non-emergent microbialitic mounds and ponds with restricted circulation.Fil:Armella, C.

Isótopos estables del carbono en restos humanos de Península Mitre y del Canal Beagle, Tierra del Fuego
No full textEl objetivo de este trabajo es realizar un análisis comparativo de los valores isotópicos del carbono (δ13C) medidos sobre gelatina ósea extraída de restos humanos procedentes de Península Mitre y del canal Beagle, Tierra del Fuego. Paralelamente, se discute esta información con aquella recabada a partir de otros estudios referidos a rastros fisiológicos y patológicos del esqueleto y del aparato masticatorio efectuados en ambas regiones. Los resultados señalan que, si bien en los análisis de rastros se encuentran ciertas diferencias, los valores isotópicos obtenidos dan cuenta de dietas análogas basadas predominantemente en la explotación de recursos marinos.Asociación de Antropología Biológica de la República Argentin
