Introduction In central Africa (Democratic Republic of the Congo, Zambia and eastern Angola), the Katanga Supergroup rocks record an up to 300 Ma complete Wilson cycle that was initiated at the >880 Ma intracontinental rifting between the Congo and Kalahari cratons, and ended at the ~573–530 Ma Lufilian orogeny. The resulting Lufilian Arc forms part of the Pan-African orogenic belts of Africa (Fig. 1; Batumike et al., 2006; Cailteux et al., 2007; Mambwe et al., 2019a). Continental break-up started with the eastward opening of the proto-Mozambique ocean, which propagated westwards into the area of the Zambezi Belt, forming the Zambian Roan Rift-Basin. Thereafter it evolved north-westwards into the area of the Lufilian Belt, forming the Congolese Roan Rift-Basin (Porada & Berhorst, 2000). Both basins widened allowing the development of Afar/Red Sea-type sedimentation in the Roan Rift-Basin, which was marked by a widespread deposition of continental (basal conglomerates, quartzites, feldspathic sandstones and shales) to marine (dominantly carbonates) rocks in the Musonoi Subgroup in the Democratic Republic of the Congo (DRC) (and the Mindola Subgroup, its stratigraphic equivalent in Zambia). These marine conditions continued in the Mines and Fungurume subgroups in DRC and in the Kitwe and Kirilabombwe subgroups in Zambia (Francois, 1987; Cailteux et al., 2005; Cailteux & De Putter, 2019).

Introduction During the late Oligocene and Neogene, glauconitic sands were deposited in shallow marine conditions across the southern North Sea Basin (Fig. 1). The deposition of these glauconitic sands was not continuous, but interrupted by several hiatuses. One of the most important and widespread hiatuses in the southern North Sea Basin coincides with the Oligocene/Miocene boundary, in the Netherlands often referred to as Savian phase (in Wong et al., 2001; Verbeek et al., 2002; Munsterman & Brinkhuis, 2004). In the northern Campine Block, a structural entity along the southern margin of the North Sea Basin, this hiatus coincides with the boundary between the Voort and Berchem Formations (Figs 2 and 3). Here, age information on the late Oligocene Voort Formation was mainly based on biostratigraphic and radiometric studies on cored sections of the ON-Mol-1 (DOV ON-Mol-1) and Weelde boreholes (DOV kb8d8e-B161; cf. Van Simaeys, 2004; Van Simaeys et al. 2004; 2005; De Man & Van Simaeys, 2004; De Man et al., 2010). The age information on the early to middle Miocene Berchem Formation was then again based on biostratigraphic studies in its outcropping areas near and within the city of Antwerp and in several boreholes across the northern Campine Block (Louwye, 2005 and references therein), not including the ON-Mol-1 and Weelde boreholes.

Introduction and objectives Evaporitic formations have been observed in Givetian strata in Annappes, Tournai and Leuze deep boreholes, located on the northern border of the Brabant Parautochthon (Coen-Aubert et al., 1980) (Fig. 1). Delmer already formulated in 1972 the hypothesis that important volumes of evaporites, including halite, could be present in the deep basement of the Mons Basin. The dissolution of these evaporites could explain the peculiarities of the Upper Carboniferous and Meso-Cenozoic deposits in the Mons Basin. Figure 1 General geological map with location of Saint-Ghislain and other deep boreholes, and indication of the Givetian and Dinantian outcrops in the Brabant Parautochthon (modified after de Bethune, 1961). Note that the Conde, Douvrain and Ghlin boreholes have not reached the Devonian units. The Annappes (FR) borehole is located 16 km WNW from Tournai city. The main objective of the Saint-Ghislain borehole, drilled between 1972 and 1976, was to test this hypothesis. During the drilling, a total of several hundred metres of anhydrite (CaSO4) was recovered not from the Devonian, as expected, but from the Lower Carboniferous. Preserved anhydrite layers are located in Middle and Upper Visean limestones, between -1950 and -2750 m, representing about 50% of the series within this section (Dejonghe et al., 1976; Delmer, 1977; Groessens et al., 1979; de Magnee et al., 1986).

Of particular interest is the Congo submarine canyon, which constitutes a permanent link between the terrestrial sediment sources and the marine sink. The Congo River delivers an annual sediment load of ~40 Tg (including 2 Tg of C) that feed a mud-rich turbidite system. Previous estimates of carbon storage capacity in the Congo turbidite system suggest that the terminal lobe complex accounts for ~12% of the surface area of the active turbidite system and accumulates ~18% of the annual input of terrestrial particulate organic carbon exiting the Congo River. In this paper, we extend the approach to the whole active turbidite depositional system by calculating an average burial of terrestrial organic matter in the different environments: canyon, channel, and levees. We estimate that between 33 and 69% of terrestrial carbon exported by the Congo River is ultimately trapped in the different parts of turbidite system and we evaluate their relative efficiency using a source to sink approach. Our carbon budget approach, which consider annual river discharge versus offshore centennial accumulation rates, indicates that about half of the total particulate organic matter delivered yearly by the Congo River watershed escapes the study area or is not correctly estimated by our deep offshore dataset and calculations.","PeriodicalId":12812,"journal":{"name":"Geologica Belgica","volume":"6 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2020-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79887730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction Contrary to the situation in South Belgium where Devonian trilobites have been the focus of numerous contemporary studies, only few papers have dealt with taxa from East Belgium (Franke, 2006; Hellemond et al., 2019; van Viersen, 2013; van Viersen & Prescher, 2009). Nearly a century ago Asselberghs (1923) reported a poorly diversified, Early Devonian trilobite association from an outcrop near Breitfeld (Sankt Vith (Saint Vith in French) area, East Belgium). Although Asselberghs described and illustrated only one trilobite species, Homalonotus maillieuxi Asselberghs, 1923, he mentioned the occurrences of several others. The present paper aims to document the Breitfeld trilobite association fully, and to discuss its potential for biostratigraphic correlations of Emsian trilobites in the Ardenno-Rhenish Mountains as well as its palaeobiogeographic affinities. 2.

More recently, this unit has been the subject of facies and stratigraphy analysis from type-sections in the Sete Lagoas High, southern Bambui basin, which have been newly interpreted as showing no evidence of glacial Cryogenian activity (Vieira et al., 2007; Rodrigues, 2008; Tuller et al., 2010). Caxito et al. (2012) interpreted the conglomeratic unit at these outcrops, as derived from local reworking of the basal platform of the lowermost unit of the Sete Lagoas Formation, along with its underlying basement. Other outcrops in adjacent areas commonly ascribed to the Carrancas Formation were recently re-interpreted as pre-glacial units deposited along fault margins (Uhlein et al., 2012, 2016).
