<p>This book presents the results of the study concerning the circulation of goods, raw material and ideas in the Calchaqu&iacute; Valley (Salta, Northwestern Argentina) during the Regional Development (900-1430/70 AD) and Inka Periods (1430/70-1536 AD). Through stylistic and provenance analyses of various materials from museums&#39; archaeological collections, it was possible to establish the diversity of goods and material that circulated to and from the valley in different moments of its occupational history. This new data, together with the already existing information about interregional connections for Calchaqu&iacute; societies, allowed for the postulation of several interaction circuits with different ecological and cultural areas like Northern Chile, Southern Bolivia, Quebrada de Humahuaca, the Puna region or the Yungas, as well as their modifications since the Inka arrival to the Calchaqu&iacute; Valley.</p>
