摘要
河北平原多目标区域地球化学调查在沧州-武强一带发现了以As、Cu、Zn、Fe、Mn、La、Th等元素为代表的多元素地球化学异常。本文利用地球化学方法,对该异常成因、生态环境效应等问题进行解释与评价。结果表明,特殊的沉积地质环境,即平原区低洼地内的自然吸附作用是形成大规模低缓地球化学异常的主要原因;异常对久负盛名的畅销果品沧州金丝小枣品质及油气热资源勘查的指示意义值得进一步研究。
Multi-objective regional geochemical survey in Cangzhou-Wuqiang area in Hebei Plain, China discovered As, Cu, Zn, Fe, Mn, Si, Ti and other elements as the representative of multi-element geochemical anomalies. In this paper, the abnormal causes, effects and other ecological problems were interpreted and evaluated by geochemical methods. Results show that the special sedimentary geological environment, namely the adsorption of natural lowland plains region is the main reason for large-scale geochemical anomalies.
