“…Detrital components such as Ti, Si, Th, Al and K are commonly used to document changes in siliciclastic input (Averbuch et al 2005; Riquier et al 2010; Śliwiński et al 2012). For the La Thure section, we plot these elements next to the MS curve (Fig.…”

Background: In this research we formulate answers to three important questions related to Givetian carbonate records and their use for reconstructing million-year-scale past palaeoenvironmental changes. First, we provide detailed illustrations of the fascinating diversity that shaped a significant shallow reefal platform during early to late Givetian time in the Rhenohercynian Ocean; secondly we improve the sedimentological model of the extensive Givetian carbonate platform in the Dinant Basin; and thirdly we evaluate the application of magnetic susceptibility as a tool for long-term trend correlations and palaeoenvironmental reconstructions. Methodology/Principal findings: These goals are reached by making a sedimentological, geophysical and geochemical study of the La Thure section. Through the early-late Givetian interval we discerned 18 microfacies ranging from a homoclinal ramp to a discontinuously rimmed shelf and then a drowning shelf. The comparison of these sedimentological results with those published for the south of the Dinant Syncline allowed us to provide an up to date model of the vertical and lateral environmental development of one of the largest Givetian carbonate platforms in Europe. This comparison also increased the knowledge on the distribution of facies belts in the Dinant Basin and allowed us to highlight the Taghanic Event. Palaeoredox proxies reveal a substantial change in the oxygenation level, from oxygen-depleted to more oxic conditions, between middle and late Givetian time. We demonstrated the relationship between variation in magnetic susceptibility values and proxies for siliciclastic input (such as Si, Al). Significance: The La Thure section is considered a key section for the understanding of Givetian paleoenvironmental changes within the internal shelf settings bordering Laurussia's southeastern margin.

“…MS intensity of Devonian carbonate rocks provides a proxy for base‐level changes during platform evolution based on detrital sediment input during lowered base level (e.g. Da Silva & Boulvain, 2006; Da Silva, Mabille, & Boulvain, 2009; Da Silva, Potma, et al, 2009; Da Silva et al., 2015; De Vleeschouwer et al., 2013; Ellwood, Crick, El Hassani, Benoist, & Young, 2000; Riquier, Averbuch, Devleeschouwer, & Tribovillard, 2010; Śliwiński, Whalen, Meyer, & Majs, 2012; Whalen & Day, 2010). The recognition of Milankovitch‐scale cyclicity in MS values has enabled cyclostratigraphic calibration of portions of the Devonian timescale (Da Silva et al., 2013, 2016; De Vleeschouwer et al., 2012; Ellwood, Tompkin, et al., 2011; García‐Alcalde, Ellwood, Soto, Truyóls‐Massoni, & Tomkin, 2012).…”

Interplay of eustatic, tectonic and autogenic controls on a Late Devonian carbonate platform, northern Canning Basin, Australia

Frasnian reef complexes along the northern margin of the Canning Basin in northwestern Australia evolved during rifting of the Fitzroy Trough. Geological investigations of the Frasnian Hull platform, which developed on an active tilted fault‐block, reveal significant lateral and vertical facies variations superimposed on prominent metre‐scale cyclicity. This study uses numerical analyses of facies and magnetic susceptibility data from three measured sections along the Hull platform to test whether a tectonic signal can be distinguished from eustatic and other signals. Geostatistical analysis of facies variations reveals an exponential distribution of thin (<3 m) facies, characteristic of stochastic depositional processes. Thick subtidal facies predominate in the Guppy Hills (GH) and southeastern Hull Range (SHR) sections near the hangingwall margin, and thick shallow‐subtidal to intertidal facies dominate the Horse Springs drillcore (HD 14) section near the footwall margin. Power and wavelet spectral analyses indicate a strong periodic component; Average Spectral Misfit and spectral optimisation methods confirm the presence of Milankovitch eccentricity signals and suggest the presence of obliquity and precession signals. However, the results also expose strong temporal and spatial variation providing evidence for tectonic control. Spectral analyses show strongest periodicity is recorded in short intervals that are not correlated across the platform and provide evidence of variations in sedimentation rate and hiatuses. Time series for the neighbouring GH and SHR sections show no overall statistical correlation, and Markov analysis indicates weakly ordered vertical facies transitions that do not correlate across the platform. Subtidal to intertidal facies data from HD 14 core suggest that at least 35% of the section is absent, almost obscuring the Milankovitch signal. The results indicate a complex set of controls on deposition on the Hull platform with local tectonic effects having produced spatio‐temporal moderation of the underlying eustatic signals and autogenic processes adding a localised stochastic response.

“…The ferromagnetic and paramagnetic minerals that have the strongest influence on the χ signal are predominantly derived from continental sources (Crick et al, 1997;Ellwood et al, 2001). Therefore, to interpret the primary character of a χ signal it is worth comparing χ with proxies for detrital input such as TiO 2 , Al 2 O 3 , K 2 O, Zr and Rb (Calvert and Pedersen, 2007;Sliwiñski et al, 2012) (Table 4). To interpret the primary character of the χ signal in the FF section published in De Vleeschouwer et al (2015), we plot the stratigraphic evolution of the χ signal against the chemostratigraphic profiles of proxy for detrital inputs (Figure 5A).…”

This study uses an integrated approach, including sedimentology, geochemistry and hysteresis magnetic measurements on a million year Givetian sequence in the southern margin of the Ardennes carbonate platform (France) to test the reliability of magnetic susceptibility (χ) records as interregional correlation tools in remagnetized settings. Furthermore, we aim to better understand the N-S depositional variations and sea-level fluctuations in the Ardennes. Sedimentological analyses revealed a complex platform evolution displaying a variety of shallow-and off-reef paleoenvironmental rocks, which ultimately allowed us to improve the sedimentological model of this area and to constrain the main sea-level fluctuations within the southern margin of the Ardennes platform. Comparison of the χ curve of this succession with previously published time-equivalent records in the western margin of the platform indicates a clear correlation between the two areas, despite the distance between the locales, their different sedimentology background and the remagnetization affecting the entire region. In contrast, the comparison of these χ profiles from the Ardennes (SW Rhenohercynian Massif, Belgian and France) with coeval data from the Rheinisches Schiefergebirge (NE Rhenohercynian Massif, Germany) do not show obvious correlations. Therefore, it is inferred that synsedimentary autogenic processes (e.g., vicinity to landmasses, wave agitation), which operate at small spatial and temporal scales affected the χ signal and could cause the lack of correlation between χ profiles.
