Besides, the great giodiversity that the country has, in terms of rocks, has been consolidating techniques as stonework/remineralization, as a viable alternative in the search for solution to problems within the agricultural sector, being an option in providing nutrientss for the soil, with the possibility of partially replacing conventional fertilizers in Brazil. To carry out the search were studied samples of outcropping mica schist withing the limits of exploration of the Minerax Company. Theses rocks belong to the Xambioá Formation (Estrondo group) in the State of Tocantins in the geological unit described in the literature as Araguaia Belt. The main objective of this work is to identify the mineralogical and chemical constituents of the mica schist samples, in order to evaluate its potential as a soil remineralizer and a source of nutrients for plants. The proposed methological study essentially involved a bibliographic survey about the geologist of the Xambioá Formation mica schist, in addition to the performance of petrographic and X-ray diffraction (XRD) analyses. The results revealed that the minerlogical composition of the mica schist samples studied presents potential for the supply of nutrients such as K, Ca, Mg and Fe, considering the presence of minerals from the mica group, in addition to albite and anorthoclase feldspars. However, the analyzes indicate levels of 28 to 44% of quartz in the rock, being an inert mineral, these levels do not fit the specific standards of remineralizers (IN MAPA 05 and 06/2016) which consider up to 25% SiO2 free (quartz), being the maximum limit for suitability of remineralizers. However, the option of a blend (mixture) with other rocks is an alternative for the Xambióa Formation shales, classified as waste in the Minerax Company exploration area, to be considered as a rock with potential for agricultural use in crops such as beans, corn and/or manioc.Acesso AbertoRemineralizadoresAgromineralMineralogiaFaixa AraguaiaRemineralizersAgromineralMineralogyAraguaia BeltCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOLOGIATrabalho de Curso - Graduação - Monografia
