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-target regional geochemical survey in the Hebei plain discovered a multi-element geochemical anomaly such as As, Cu, Zn, Fe, Mn, La, Th and other elements in the Cangzhou-Wuqiang area. In this paper, we use geochemical methods to explain and evaluate the causes of the anomaly and ecological environment effects. The results show that the special sedimentary geological environment, that is, the natural adsorption in the plain lowland is the main reason for the formation of large-scale low-geo-geochemical anomalies. The significance of the anomaly to the prestigious best-selling fruit Cangzhou Jizo jujuba quality and hydrocarbon exploration Worth further study.
