ANTHROPOGEOMORPHOLOGY - MAN AS A GEOMORPHOLOGIC AGENT: THEORETICAL BASIS AND ANALYSIS OF CHRYSOTILE EXTRACTION IN MINACU, STATE OF GOIAS, BRAZIL
MetadataShow full item record
The present work show a spatial and temporal analysis from the chrysotile asbestos and the relation with a development of anthropogenic forms in the city of Minacu, State of Goias. The analyses were done from the correlation between the morphological and morphometric aspects from area and historical data of the mineral production. The extraction process began in 1967 in a rudimentary way, although with the increase of the global demand for the ore and the technological modernization process, the changes in the landscape became increasing and cumulative. During this period were removed hundreds of millions of tonnes of rock and soil, drawing up armholes and embankment of waste that surprised by its dimensions. Linked to these analyzes, we have a theoretical discussion about the Anthropic Geomorphology as specialty of Geomorphology, applied to changes in the physical environment caused by direct and indirect human actions.
