Abstract

Mining is one of the most impacting human activities to natural resources, and that can profoundly affect ecosystem resilience depending on the level of soil degradation. Thus many mined areas are not effectively recovered to the point of restoring relevant part of biodiversity and ecosystem services, restricting rehabilitation. If the physical, chemical and microbiological soil properties are not considered in forest restoration, resilience is not viable, and consequently, the ecosystem will not restore its ecological functions. In particular, the physical and chemical attributes are the first to be recovered to establish vegetation, facilitating ecological succession. The recovery of the chemical attributes denotes attention, since soils of tropical ecosystems are generally poor in nutrients. The mineralogical composition of the soil is intrinsically linked to that context by conditioning the physical and chemical soil properties, in particular its physical structure, which may different managements that compartment are needed and chemically mineralogy vary significantly among soil types, so in terms of fertility, working the soil as a reservoir or drain nutrients. The aim of this study is to determine the total and clay fraction in newly mined soils, forests and restoration of native forests and forest rehabilitation process mineralogy. The study areas are located in the city of Pocos de Caldas / MG and belong to ALCOA Aluminum. In each study area, ie each sample unit correspond to a collection point, this being composed of 15 sub-samples, the 0-5, 5-10, 10-20, 20-40, 40-60 cm. The mineralogy of the soil will be determined by X-ray diffraction (XRD). (AU)
