Sentence examples for degree of fractionation from inspiring English sources
Conversely, samples with larger carbonate fractions exhibited a greater degree of fractionation, albeit with lower total abundance.
Figure 6 Distribution of total REE and degree of fractionation in samples with and without major fractions of illite or calcite.
This degree of fractionation was used to represent the overall "unevenness" or entropy of the PAAS-normalized profile.
The latter finding seems intuitive as the degree of fractionation is calculated relative to a composite of clayey shales (PAAS).
However, as intercellular concentrations of CO2 decline, so too does the degree of fractionation, resulting in a greater proportion of 13C being fixed and thereby an increase in the δ13C of photosynthates.
The overall degree of fractionation in a sample was defined as the sum of the absolute values of one minus each of: HREE/MREE ratios, MREE/LREE ratios, Ce anomalies, and Eu anomalies.
Based upon rare earth element fractionation observed in desert varnish it has been argued that the degree of element fractionation observed is inconsistent with isochemical leaching and reprecipitation within the same rock [26].
Sometimes a set of samples will form from a single reservoir but with each one having experienced a different degree of mass fractionation.
The relatively large amounts of K-feldspar (Kavg is 4000 μg g−1) and low degree of HREE/LREE fractionation suggest that this landscape is weathered less than generally assumed.
Although it is well known that solar energetic particles are depleted in elements with first ionization potential (FIP) greater than ∼10 eV, it is less well known that the degree of FIP fractionation varies from event to event.
Since HD is primarily destroyed by the inverse reaction of equation (8), the difference in the zero-point energies of H2 and HD can lead to a significant degree of chemical fractionation at low temperatures, which boosts the HD/H2 ratio well above the cosmological D/H ratio of about 10−5.
