The chemical composition of the continental crust is critically important for understanding its formation and evolution and, ultimately, understanding Earth differentiation. Here we provide a brief review of the chemical composition of the continental crust, with an emphasis on studies from China. The ...
THE main object of the research described in this monograph was to ascertain the amounts of many of the less common elements, including, certain members of the rare earth series, in the minerals and rocks of the East Indian Archipelago....
P-wave velocities of both the lower and total crusts in East China are slower by 0.2–0.4 km s 1 compared to various global estimates. Correspondingly, the total crust shows an more evolved composition and is characterized by a significant negative Eu anomaly (Eu/Eu = 0.80), low Sr/Nd (...
Each tectonic unit has a relatively homogenous middle crust composition which is broadly similar to the composition of the total crust. The lower crust in East China can be divided into two layers both seismically and chemically. The upper lower crust is characterized by Vp = 6.7 km s−1 an...
A survey of a large (45,000 analyses) global-wide data base on the chemical composition of the three most abundant rocks of the earth's crust (shales, basalts, and granitoids) is conducted. It is demonstrated that, during the entire geological history of the earth, the average compositions...

The effective recovery of moss crusts after long-term desiccation is vital for their survival. In this study, we analyzed the changes in micromorphology, ultrastructure and chemical composition in Bryum argenteum samples desiccated for 1 week or 1 year. We used non-destructive and anhydrous methods...
Road dust was investigated within Philadelphia, a major United States city with a long history of industrial activities, in order to determine pollution levels. Almost all of the investigated minor elements were enriched relative to the continental crust. Furthermore, mean concentrations of Cr, Co,...
[130,131] pointed that biofilm growth is largely depended on light and temperature, as well as on the trophic state of the media. Characterizing chemical composition of biofilm which can be achieved by Fourier transform infrared (FTIR) spectroscopy [122], SEM-EDS [172], microfluidics [46,139...
