| Abstract: | Based on the study of the difference between aqua regia solution and HF-HClO_4-HNO_3-HCl solution and the distribution of elements in flood plain sediments A, B and active stream sediments, the authors hold that flood plain sediments A can be used as the effective sampling media in the ultra-low density deep penetration geochemical survey in the forest-swamp area of central Heilongjiang Province. |
