查询词典 anomalies

In model experiments, we find that the deviation of the first derivative calculated by Fourier transform is very large to comparing with the theoretical derivative, but the fitting effect of the derivative of anomalies calculated by cosine transform is very good. The calculation accuracy of data are all very high except that errors of several data on the boundary are large because of the residual Gibbus effect induced by finite truncation of gravity anomalies. Errors are -009%～5%.

Recent developments in the research on the geology and geochemistry of the newly-discovered clayey breccias at the lop of the Xiaochaka Formation in the Juhuashan, Xiaochaka and Shishuihe areas, Qiangtang Basin, northern Tibet have disclosed that mineral compositions, textures and structures, occurrences and sectional architectures of the clayey breccias agree well with those of the paleo-weathering crust in these areas. Compared with the bedrocks, the paleo-weathering crust is characterized by the leaching out of CaO and CO2, and relative enrichment of SiO2, Al2 O3, Fe2O3, K2O, Na2O, MnO and P2O5. The clayey weathered residues in the paleo-weathering crust are characterized by marked enrichment of REEs, much higher contents of LREEs than those of HREEs, markedly positive Ce anomalies and negative Eu anomalies, and a noticeable increase in other element contents besides Mo, Sn and U from the clayey weathered residues.

The results show that the white thick-bedded siliceous rocks have high contents of SiO2 and Al2O3 and high ratios of Al/ and Al2O3/(Al2O3+ Fe2O3). The ∑REE are low, and the North American shale-normalized REE patterns are characterized by enrichment of LREE and absence of Eu and Ce anomalies, which suggest that the white thick-bedded siliceous rocks might have been formed in the continental margin environment and affected significantly by terrigenous constituents. The anatase-rich siliceous rocks have high contents of TiO2, Fe2O3, Cu and V but low Al/(Al + Fe+ Mn) and Al2O3/(Al2O3 + Fe2O3) ratios. The ΣREE are high, the North American shale-normalized REE patterns are obviously characterized by left-oblique to flat styles of curves and slight negative Ce anomalies, implying that they might have been formed in an oceanic ridge environment.
