| Geochemical Probe into China’s Continental Crust |
| The goals of the project are to (1) develop four geochemical methodologies, namely analytical methods for all the elements, deep-penetrating geochemical methods, earth crust geochemical model and global geochemical data visualizing software, (2) establish China’s nationwide geochemical baselines for rocks and soils, (3) make the crust geochemical models by pilot study of three geochemical transects to display element distribution in upper, middle and lower crust, (4) explore the evolution of elements in different tectonic plates of China with geological times from Archaean to Quaternary, and (5) identify areas of interest for mineral resources and environments. To-tally 15 000 typical rock samples and 6 000 soil samples will be collected in the China Geochemical Baselines Networks covering the whole mainland and 6000 samples will be collected along the 3 transects, with the deter-mination of 78 elements. The project includes the following five programs: China Geochemical Baselines, China Continental Earth Crust Geochemical Reference Model, Deep-penetrating Geochemistry through Cover and Basin, Geochemical Earth Software, and Geochemical Evolution with Geologic Times along Transects. |
