“…DR2) demonstrate a variable underestimate of the clay contributions determined by instrumental analysis relative to those separated by pipette analysis (cf. McCave et al, 1986;Loizeau et al, 1994;Konert and Vandenberghe, 1997;Beuselinck et al, 1998;Buurman et al, 2001;Blott and Pye, 2006;Fedotov et al, 2007). The signifi cant clay content in Chinese eolian deposits determined by the pipette method, especially for the Neogene samples with an average clay content of ~34% ± 5% (n = 22), raises fundamental sedimentological questions for future studies on formation processes of clay-sized particles in the mid-latitude Asia region.…”

“…Other authors have emphasized the contribution that particle density makes to differences between laser and sedimentation methods. Fedotov et al (2007) indicated that over-estimation of the clay fraction by 1.5-5 times can be related to differences in particle density. Zobeck (2004) observed that correlation between laser and sedimentation methods varied with mineralogy and was stronger when non-calcareous soil samples were separated from calcareous ones.…”

“…A lézerdiffrakcióval mért kisebb agyagtartalmakat általában az agyagfrakciót alkotó talajrészecskék gömbszerűtől való eltérő alakjával magyarázzák (MATSUYAMA & YAMAMOTO, 2004;BLOTT & PYE, 2006;FEDOTOV et al, 2007;. Azt azonban szintén megállapítják, hogy az eltérő műszertípusok, mű-szerbeállítások, az előkezelési módszerek bizonytalanságai megnehezítik a mérési eredmények összehasonlítását, a módszerek közti konverziós technikák kidolgozá-sát (RYŻAK & BIEGANOWSKI, 2011;MADARÁSZ et al, 2012;SOCHAN et al, 2012;CENTERI et al, 2015).…”
