International audience; The Neoproterozoic Schisto-Calcaire Group (630 to ca. 580 Ma) was deposited on an extensive carbonate shelf in the margin of the Congo Craton in the Niari-Nyanga and Comba subbasins (Gabon and Republic of the Congo). It consis

This study provides new constraints on the paleoenvironmental, eustatic and carbon isotopic models of the cap carbonate-like rocks of the Dolomie Tigree Formation in the Katanga region, Democratic Republic of the Congo. The study integrates detailed

We report the discovery of 715 to ca. 810 million–year–old fungal fossils through molecular characterization of vestigial chitin.
Precambrian fossils of fungi are sparse, and the knowledge of their early evolution and the role they played in

Stratigraphic correlations in mid- to late-Proterozoic carbonates of the Democratic Republic of Congo using magnetic susceptibility

Autor: Simo Spassov, Xavier Devleeschouwer, Franck Delpomdor, Alain Préat

Publikováno v: Sedimentary Geology. 351:80-101

In this paper, we have tested the application of magnetic susceptibility measurements in Cu-Ag-Zn-Pb-(Fe)-mineralized carbonates of the BIe subgroup (Democratic Republic of Congo) as an efficient tool for regional and global high-resolution stratigra

Pre- and post-Marinoan carbonate facies of the Democratic Republic of the Congo: Glacially- or tectonically-influenced deep-water sediments?

Autor: Luc Tack, Alain Préat, Nicholas Eyles, Franck Delpomdor

Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 457:144-157

The upper carbonate-rich parts of the West Congo Supergroup (~ 1000–560 Ma) from the Democratic Republic of the Congo have hitherto been considered as a record of abrupt eustatic and climatic events accompanying glaciation and deglaciation of a Sno

Cyclicity and sequence stratigraphy of the Neoproterozoic uppermost Haut Shiloango-Lukala carbonate ramp system in the Lower Congo region (Democratic Republic of the Congo): Example of tectonostratigraphic control versus climatic changes

Autor: F. Kant, L. Tack, Alain Préat, Franck Delpomdor

Publikováno v: Journal of African Earth Sciences. 160:103636

During the Cryogenian-Ediacaran, tectonically- and climatically-driven perturbations created sea level changes . Snowball Earth-type glaciations suggest ~500–800 m sea level fall or at least 1,000–1,500 m in eustatic sea-level change as a result

The Ediacaran Schisto-Calcaire Group is a ∼1300 m-thick succession belonging to the West Congo Supergroup in Central Africa. In the Comba Basin, it consists of three carbonate-dominated units defined as formations (SCI to SCIII) that are unconforma
