Abstract

Abstract

Detailed studies have been conducted of the trace elements in ores, wallrocks of intrusion and orebodies in the Yinshan deposit. It is shown that∑ REE increased in all samples but those close to the intrusion and orebodies decreased.Altered wallrocks are characterized by lower w(LREE)/w(HREE)ratios and depleted in Eu compared with their fresh counterpart. It is suggested by calculation that less much. While E.D.Weinberg expanded the G.Bertrand law and further revealed that certain quantity of manganese may allow some bacteria to grow well but may not be suitable for them to produce bacteriophage. Biologic vital double threshold element content and its physiological effect can be expanded to different hydrogeochemistry zones in hydrogeologic unit. In elements lioxiviated(leached), transferred strongly hydrogeo-chemistry zone, biologic physiological effect and element content show negative correlativity. In elements enrichment, lioxiviated, concentration by evaporation hydrogeochemistry zone and environment polluted by some elements superfluous, biologic physiological negative effect and element content show positive correlativity, between them which above is the element content fitting zone. Take the Lishi-Liulin hydrogeologic unitof Shanxi Province as an instance: The lack of selenium, iodine and fluorine in the hydrochemistry zone with element leaching and loss causes KBD, IDD, and tooth decay, which is in a negative correlativity with element content, respectively. While in the element lioxiviation and enrichment zone, fluorine is superfluous.As a result, endemic fluorosis occurs and its sick rate shows positive correlativity with content.
- optimum nutrition law,
- hydrogeochemistry zone,
- physiological negative effect,
- double threshold element,
