Mapeamento geológico na delimitação de rochas fosfáticas no município de Bodoquena-MS

Abstract

Mineral research works are of extreme importance for the recognition and incorporation of new deposits. According to a report published by the Department of Economic and Social Affairs in 2017, the world population, despite low fertility rates, will be 9.8 billion people by 2050.As a consequence of this data, it follows the immediate need to supply this food demand. Among the great challenges facing these statistics, there is a growing reevaluation and rationalization of food practices and consequently agribusiness. The fertilization of the planting of several crops, as a means of optimization and improvement in production, has as fundamental chemical element the macronutrient called phosphorus which, when bound to four oxygen atoms, produces the trivalent phosphate anion. Recognizing the great importance of identifying and evaluating reserves of this mineral good in the country, the main objective of this work is to recognize and delimit lithologies associated with phosphate occurrences in the region of Bodoquena, Mato Grosso do Sul. From a basic geological mapping in scale of detail (1: 4.000), it was recognized lithologic limits, zones and structures related to mineral occurrence. The present study represents an important contribution in the conduction and planning of future studies associated to the determination of targets and analysis and characterization of ore contents.
