摘要
在野外调查及采样分析的基础上,通过综合研究已有资料,对上杭县旧县镇铁东水库中的铁锰质超标原因进行了分析,认为水库中由于残留的有机质与库区内软锰矿层、黄铁矿化岩石在水介质的参与下,发生氧化-还原反应和酸碱反应等一系列现代地球化学作用,形成了一个酸性递增、铁锰离子加快析出的递进的地球化学过程,从而导致水库水中铁锰质超标。
Based on the results of the field investigation and sampling analysis, the author made a study on the cause of transnormal ferrimanganic materials in the Tedong reservoir of Shanghang County. It is considered that the transnormal ferrimanganic materials in the reservoir come from a series of the modern geochemical process which results in increasing acidity and speeding liberation of ferrimanganic ions. The modern geochemical process includes the oxidation-reduction reaction and acid-base reaction which take place from the remainder organic matters, pyrolusite strata and pyritization rock in the reservoir region participating in the aqueous medium.
