We present data from a reconnaissance geochemical environmental survey (stream sediments) in the Limarí watershed (northern Chile), and include information from the neighboring Elqui Basin for a combined analysis. Given that the region has a long historical record of mining activities, important environmental disturbances were expected. However, one of the rivers in the Limarí watershed that was chosen to serve as a baseline, as no mining activities had ever taken place along the valley, showed… CONTINUE READING
