“…With this technical setting, we could not reliably measure Si, as in the "Soil Fundamental Parameters" method the SiO2 mass fraction is used to sum the total weight to 100% (e.g. explained in more detail in Sinnesael et al, 2018). The fundamental parameters method makes use of the theoretical relationship between X-ray fluorescence and material composition as determined by Sherman (1956).…”

“…The pXRF measurements were not calibrated using external reference materials. As such it is more relevant to consider relative variations in the elemental concentrations data than interpreting absolute concentrations (Sinnesael et al, 2018). As a general principle the pXRF is also less suitable to measure very light (<Al) or heavy elements (>Ba); or elements that only occur in trace amountsalso depending on the instrument used (Beckhoff et al, 2006).…”

Abstract. To expand traditional cyclostratigraphic numerical methods beyond their common technical limitations and apply them to truly deep-time archives we need to reflect on the development of new approaches to sedimentary archives that traditionally are not targeted for cyclostratigraphic analysis, but that frequently occur in the impoverished deep-time record. Siliciclastic storm-dominated shelf environments are a good example of such records. Our case study focusses on the Middle to Upper Ordovician siliciclastic successions of the Armorican Massif (western France), which are well-studied in terms of sedimentology and sequence stratigraphy. In addition, these sections are protected geological heritage due to the extraordinary quality of the outcrops. We therefore tested the performance of non-destructive high-resolution (cm-scale) portable X-ray fluorescence and natural gamma-ray analyses on outcrop to obtain major and trace element compositions. Despite the challenging outcrop conditions in the tidal beach zone, our geochemical analyses provide useful information regarding general lithology and several specific sedimentary features such as the detection of paleoplacers, or the discrimination between different types of diagenetic concretions such as nodules. Secondly, these new high-resolution data are used to experiment the application of commonly used numerical cyclostratigraphic techniques on this siliciclastic storm-dominated shelf environment, a non-traditional sedimentological setting for cyclostratigraphic analysis. In the lithological relatively homogenous parts of the section spectral power analyses and bandpass filtering hint towards a potential astronomical imprint of some sedimentary cycles, but this needs further confirmation in the absence of more robust independent age constraints.

“…Recent studies have commented on the use of portable XRF (pXRF) in sedimentary rock analyses, particularly for linking elemental changes to stratigraphic and paleoclimatic observations, and the calibration of pXRF instruments to other elemental analyzers (Dahl et al, 2013;de Winter et al, 2017;Ibañez-Insa et al, 2017;Kessler & Nagarajan, 2012;Lenniger et al, 2014;Mejia-Pina et al, 2016;Quye-Sawyer et al, 2015;Rowe et al, 2012;Thibault et al, 2018). The ability to measure elemental concentrations, and sensitivity of modern pXRF instruments, provides a clear rationale for employing pXRF analysis for cyclostratigraphy (e.g., Ruhl et al, 2016;Sinnesael et al, 2018;Thibault et al, 2018). The merits of using pXRF analysis for cyclostratigraphy have been discussed by Sinnesael et al (2018).…”

Cyclostratigraphic studies are used to create relative and high‐resolution time scales for sedimentary successions based on identification of regular cycles in climate proxy data. This method typically requires the construction of long, high‐resolution data sets. In this study, we have demonstrated the efficacy of portable X‐ray fluorescence spectroscopy (pXRF) as a nondestructive method of generating compositional data for cyclostratigraphy. The rapidity (100 samples per day) and low cost of pXRF measurements provide advantages over relatively time‐consuming and costly elemental and stable isotopic measurements that are commonly used for cyclostratigraphy. The nondestructive nature of pXRF also allows other geochemical analyses on the same samples. We present an optimized protocol for pXRF elemental concentration measurement in powdered rocks. The efficacy of this protocol for cyclostratigraphy is demonstrated through analysis of 360 Toarcian mudrock samples from North Yorkshire, UK, that were previously shown to exhibit astronomical forcing of [CaCO3], [S], and δ13Corg. Our study is the first to statistically compare the cyclostratigraphic results of pXRF analysis with more established combustion analysis. There are strong linear correlations of pXRF [Ca] with dry combustion elemental analyzer [CaCO3] (r2 = 0.7616) and of pXRF [S] and [Fe] with dry combustion elemental analyzer [S] (r2 = 0.9632 and r2 = 0.9274, respectively). Spectral and cross‐spectral analyses demonstrate that cyclicity previously recognized in [S], significant above the 99.99% confidence level, is present above the 99.92% and 99.99% confidence levels in pXRF [S] and [Fe] data, respectively. Cyclicity present in [CaCO3] data above the 99.96% confidence level is also present in pXRF [Ca] above the 98.12% confidence level.

“…These technological advances were boosted by geological exploration and mining prospection (e.g., Fabre, 2020), environmental studies (e.g., Turner et al, 2018), and/or planetary rover missions (Edwards, 2018), along with many other applications. Specifically, in archaeometry, more and more non-destructive tools in spectroscopy and spectrometry are used to constrain the mineralogy, the chemical composition, and the physical properties of archeological material, by e.g., portable magnetic susceptibility (pMS; e.g., Williams-Thorpe and Potts, 2002;Szakmány et al, 2011), portable XRF (Oyedotun, 2018;Müskens et al, 2018;Sinnesael et al, 2018), portable Gamma-Ray spectrometry (pGRS; Puccini et al, 2014), handheld Laser-Induced Breakdown Spectroscopy (HH-LIBS; Senesi et al, 2018), portable Raman spectroscopy (e.g., Bersani and Madariaga, 2012) or spectrophotometry (Rogerio-Candelera, 2016;Boulvain et al, 2020). Combining these tools and the interpretation opens the door to high accuracy determination, discrimination, and sourcing of archeological materials (e.g., Liritzis and Zacharias, 2011;Papakosta et al, 2020).…”

We present a workflow to conduct a full characterization of medium to coarse-grained igneous rocks, using portable, non-invasive, and reproducible approaches. This includes: (i) Image Analysis (IA) to quantify mineral phase proportions, grain size distribution using the Weka trainable machine learning algorithm. (ii) Portable Xray fluorescence spectrometer (PXRF, Bruker Tracer IV) to quantify the whole-rock's chemical composition. For this purpose, a specific calibration method dedicated to igneous rocks using the open-source CloudCal app was developed. It was then validated for several key elements (Si,
