The area consists of basic lava flows succeeded by acids lava flows. All of them included in the Serra Geral Group, Paraná Basin, with the hydrothermal features. There are massive and vesicular basalts and acid brecciated volcanic rocks. The first samples were discovered and collected in 2015 by geologist Rodrigo Del Olmo Sato while working.
