Miraflores rocks in Tierra del Fuego (southernmost South America): Hunter-gatherer procurement, optimal pathway analysis and social interaction

Hunter–gatherer mobility and technological landscapes in southernmost South America: a statistical learning approach

“…As the vast majority of the territory in Otway Sound was occupied by maritime societies, it has been suggested that green obsidian was distributed and controlled by these groups. On the contrary, terrestrial hunter–gatherers controlled the circulation of Miraflores rocks throughout IGTDF [19]. …”

“…Nevertheless, it is worth noting that prior analyses have focused on the geographical distribution of particular items of material culture to trace contacts. Examples of such items are raw materials [18][19][20], decoration patterns of portable art [21] or singular lithic and bone designs [22]. By contrast, in the present research, we rely on a comprehensive database which encompasses a wide range of technological variables to overcome the fragmentary nature of the archaeological record, thus broadening the analytical capabilities offered by material culture.…”

Circulación de bienes, uso del espacio interior y espacios programados en los Archipiélagos de Fuego-Patagonia en tiempos recientes

“…La toba riolítica y la toba silicificada Miraflores -rocas con procedencia en el extremo norte de la Isla Grande (Borrazzo, 2012)-tienen una distribución prácticamente panfueguina. Sin embargo, en el archipiélago fueguino austral y al sur de la cordillera Darwin, la primera sólo está presente en la península Mitre (Pallo & Borrazzo, 2016;Borrazzo et al 2019). Esta toba riolítica Miraflores es adecuada para ser usada para la confección de alisadores o afiladores.…”

Past human populations and landscapes in the Fuegian Archipelago, southernmost South America

“…Particularly in the Fuegian Archipelago (southernmost South America; Fig. 1), some studies have considered environmental, geographic, ecological, and/or climatic factors to explain past human behavior (e.g., Borrero, 1999, 2008, 2013; Barberena, 2004; Muñoz, 2007; Borrazzo et al, 2008; McCulloch and Morello, 2009; Morello et al, 2009, 2012, 2015a; Zangrando et al, 2009; Coronato et al, 2011; Pallo, 2011, 2017; Fernández, 2013; Prieto et al, 2013; Pallo and Ozán, 2014; San Román, 2014; Mansilla et al, 2016; Pallo and Borrazzo, 2016; Fernández et al, 2018). However, systematic contributions discussing human–environmental interactions in the entire Fuegian Archipelago across the Holocene are still scarce.…”

“…The intensity of human occupation increases in the late Holocene for the whole study area. A broad distribution of certain technological items (e.g., microlithic projectile points) and raw materials (e.g., exotic obsidian from the southwestern archipelago and the Miraflores tuff and silicified tuff) across the entire Fuegian Archipelago and southern coasts of continental Patagonia also provide evidence of increasing interaction between terrestrial and maritime populations by the late Holocene (e.g., Álvarez, 2009; Borrazzo et al, 2015, 2019; Morello et al, 2012, 2015b; Pallo and Borrazzo, 2016). By this time, the consumption of guanaco increases in the northern steppe (Santiago, 2013), while processes of subsistence intensification are described in the southern area (Álvarez, 2009; Tívoli, 2010; Zangrando, 2009).…”
