Plan for the application of resources from the Institutional Technical Reserve for Research Infrastructure at IGc/USP for the 2024 financial year according to the Congregation's decision of 06/12/2024. The resources will be applied to contracting important and critical services to improve the Institute's scientific research infrastructure, taking into account compliance requirements, as w…
The Neoproterozoic era, spanning from 720 to 539 million years ago, was marked by profound transformations in all its envelopes and witnessed the emergence and diversification of metazoan life, culminating with the appearance of major animal phyla, in the Cambrian. The Cryogenian period (720-635 Ma) featured extreme glacial epochs and the reemergence of banded iron formations, signaling t…
The late Neoproterozoic witnessed remarkable changes in almost all envelopes of the planet. The biosphere experienced one of its most fundamental evolutionary steps with the rise of complex life forms, which was accompanied by fundamental changes in oceanic deep-water redox conditions, fluctuations between extreme climate modes, and major changes in the configuration of continents. In thi…
The objective of the proposed work is to move forward our understanding of the evolutionary adaptations of early life to the increasing atmospheric oxygen concentration. Our aim is to characterize the evolving biosphere and the changing environments across the 2.45 to 2.32 Ga old Great Oxidation Event and the ~0.8 to 0.54 Ga old Neoproterozoic Oxidation Event. To achieve this goal, we wil…
The study of detrital minerals, specially the zircon, has been established as an extremely useful approach on the interpretation of the composition and history of modern and ancient sediments. Regarding the Paraná Basin, provenance studies are still in a reduced number, despite its enormous dimension and thickness, with sedimentary rocks that represent various depositional settings. Thus,…

Nitrogen is an element that conditions life on Earth, and the understanding of how its biogeochemical cycle evolved through geological time provides valuable information about variations of the ocean chemistry, since the speciation of this element is strongly controlled by the redox conditions of the depositional environment. This project aims to obtain N isotopic data (´15N) of carbonate…
The evolution of the Earth and its processes to sustain life have been a major research topic during the past decades. Questions regarding the planet's habitability, including when the ocean and the atmosphere became oxygen-rich, still imposes challenges to our understanding of how and when these resources evolved. This increase in atmospheric oxygen through Earth's history modulated an e…
The most remarkable changes in the Earth's life evolution took place during the Ediacaran Period, when the first macroscopic complex organisms emerged. Geochemical proxies show major fluctuations coupled to the paleontological record appearances, which point to the evolution of the whole ocean-atmosphere-biosphere system. The main event considered as the trigger for this turning point is …

The evolution of the Earth and its inter-relations with life have been a major research topic during the past decades. Questions regarding the planet's habitability, including when the ocean and atmosphere became oxygenated, still imposes challenges to our understanding of how and when these resources evolved. The geological record, particularly iron formations (IF), carbonates and shales…
Great biological innovations associated with major geochemical disturbances characterize the Ediacaran geological record, at the end of Neoproterozoic Era, which are attributed to the final oxygenation of Earth's surface environments. Carbon and sulfur stable isotopes studies are key tools for inferences of major oxidation events in the marine environment, close related in time with the a…
