Sentence examples for trace element abundances from inspiring English sources

Recommended values for trace element abundances by Rocholl et al. (1997) were used.

Trace element abundances are low in metamorphic fluids at subsolidus conditions, but become significantly elevated in anatectic melts at supersolidus conditions.

All hydrous minerals are important hosts of given trace elements in HP to UHP metamorphic rocks, but with significant differences in trace element abundances.

The high correlation of major and trace element abundances between the Xinmocun lacustrine samples and the loess-soil samples from the Chinese Loess Plateau (CLP) supports the previous view of the eolian origin of the Xinmocun lacustrine sediments.

Therefore, in this study, we utilised trace element abundances and their ratios for the characterisation of kerogens from the central Niger Delta since it is cheaper to generate data on trace elements than the data on organic content of source rocks.

In this study, we assumed that the EER formed at shallow, upper-mantle pressures because previously estimated trace element abundances of the EER resemble those of a melt generated in the upper mantle (Korenaga 2009a) and, in particular, the upper few hundred kilometers where clinopyroxene is stable (Boyet and Carlson 2005).

Based on trace-element abundances, this trend is plausibly caused by increasing degrees of batch partial melting at a constant bulk distribution coefficient (Yamamoto 2011).

Trace-element abundances and Sr Nd Pb isotopes suggest that Akagi magmatism is characterized by interactions between mantle-derived magma and lower-crustal materials (with amphibole fractionation; Kobayashi and Nakamura 2001).

The negative Ta, Nb and Ti anomalies, low Rb/Ba ratios (0.01 0.15) and high incompatible trace element (such as Th, U) abundances of the basalts suggest that metasomatism may have occurred during the Late Carboniferous subduction.

Analysis of major element abundances, ratios, and trace element ratios indicates that the dust provenance of the Xinmocun lacustrine sediments is different from that of the CLP, and is similar to that of the loess at Ganzi and Hongyuan nearby the study area.

Such fluctuations of trace element concentrations might be associated with abundance of microcrystalline quartz (Götze et al. 2001).
