The Neoproterozoic Era (1000 - 541 Ma) is one of the most dramatic in Earth history: metazoans evolved, the supercontinent Rodinia formed and broke apart, the global carbon cycle underwent high-amplitude fluctuations, oxygen concentrations rose and climate experienced at least two episodes of worldwide glaciation.
The specific targets of this project are the Ediacaran-Cambrian Transition (ECT; c. 560-530 Ma) strata of west Brazil (Corumbá Group), south China (Doushantuo, Dengying and equivalent formations) and south Namibia (Nama Group). Our objective is to create a core network of correlative ECT strata that will enable constructing a highly resolved, temporally constrained geobiological, stratigraphic and geochemical database, as well as provide a legacy archive for future research. The goal is to understand the drivers of the Neoproterozoic Earth system revolution.

GRIND-Brazil Sampling Party
The first GRIND-Brazil Sampling Party took place 08-09 May 2023
in the BGR core repository in Berlin Spandau.
Cores Ready for Shipping
The 111 boxes with cores of GRIND-Brazil are now ready to be shipped
to the ICDP repository.
Brazil finished Drilling!
End of Hole 3B. After crossing the contact of Tamengo and Bocaina formations at 115 m, we stopped the drilling operations at 123.10 m.
