Abstract

This new reinterpretation of the Quaternary evolution of the Pecora River area has several implications, in particular on the nature of the arsenic anomaly known in this area and mainly confined to the fluvial terrigenous deposits. Specifically, the erosion and dispersal of As-bearing mineralization emplaced between the late Pliocene and the Quaternary in fractures and faults affecting the bedrock of the Arsenti Mount area, was possibly driven by the sedimentary development of the Pecora River catchment resulting in the landforms and deposits described in this study. As a consequence, the As anomaly known in this area may have resulted from fully natural phenomena such as relief denudation and sediment dispersal. - (NF)
