Sentence examples for geological blocks from inspiring English sources
Fig. 8 An ESR CI plot for riverbed sediments from each of the geological blocks in the Yangtze drainage basin.
Therefore, the ESR and CI values of the samples can be explained by a mixing of the values of individual geological blocks.
Figure 8 shows clear differences in ESR signal intensity and CI values among the three sediment size fractions, with the nature of the differences depending on the composition of the geological blocks.
The values for each tributary reflect the age and type of bedrock in the tributary basin and show distinct regional variations according to the distribution of geological blocks within the Yangtze basin.
The geological blocks that make up the basement rocks in the Yangtze River drainage basin are classified into the Qamdo Block and Yidun Arc (QY), Songpan Garze terrane (SG), Qinling orogenic belt (QL), Yangtze Block (YZ), and Cathaysia Block (CX).
As the basement rocks in each geological block are generally considered as the source of younger detrital sediments in the block, each sample is categorized with respect to the geological block(s) exposed in its drainage basin (Fig. 8).
For this condition, 5 different sampling grids were generated from the geological block model of Sungun copper mine.
Fig. 3 Perspective towards the north of the 3D geological block model for the Bradys geothermal area used for 3D geophysical modeling.
Thus, in this subsection, we discuss the differences in ESR signal intensity and CI values among the three size fractions representing each geological block.
In summary, our data demonstrate that the ESR signal intensity of the fine-silt fraction (4 16 μm) extracted from riverbed samples collected on each geological block are consistent with the ages of the dominant rock types in that block.
Figure 8a shows ESR signal intensity and CI values of quartz in the fine-silt fraction of river sediments, with symbols indicating the geological block(s) exposed in the drainage basin of the sample.
