The Thermal Water of the Touristic Polo of Águas de São Lourenço occur in the southeastern Mato Grosso 150 km from Cuiabá, of municipalities of São Vicente, Juscimeira and Jaciara. The region is located in the units of Guimarães Plateau that presents features of cuesta relief of Serra dos Coroados and São Jerônimo and by Rondonóplis Depression formed by the São Lourenço River valley, where are exposed rocks of the Paraná Basin (Furnas Ponta Grossa, Aquidauna, Botucatu and Serra Geral Formations). The mineral waters correlate to large regional flexures, faults and fractures, which constitute reflex structures or reactivation of older structures of the basement rocks. The hydrothermal conditions of the area reflect the interaction of several factors: the significant gravity anomalies surrounding subsurface São Vicente granite and the largest regional heat flow in this area. In addition, the significant topographically recessed area with higher altitudes, hydrogeological recharge, the amount of sandy rocks favorable to the accumulation, and intense fracturing high permeability for rainwater recharge aquifers. This situation enables the Furnas sandstone aquifer, confined by impermeable sediments of Ponta Grossa Formation to stay with thermal and keep partial to resurgent. The health resort is a major tourist hub for the state of Mato Grosso and municipalities survive economically on tourism, which depends on the infiltration of rainwater for renovation surface and thermal spring.
