摘要
通过对托克逊幅部分1:20万区域化探中土壤测量资料的整理分析,认为托克逊地区多元素综合异常是该区由盆地边缘向中心沉积物迁移分异与表生环境下元素再次分异富集的结果,其东部异常元素组合特点又反映该区深部有油气田存在的可能。多种元素异常丰度已超过地表土壤环境污染规定标准阈值,提出该区可能对农作物和人类健康造成危害的元素有F、Sr、Mo、MgO、V、Th、La、U、Ti、Mn,并圈定污染区范围。
According to analyse part data of soil survey in regional chemical exploration (1:200000, Tuokesong map), the author thought that multi-element composite anomalies were caused by migration differentiation of sediment from margin to center of the basin and re-differentiation under surface environment. The characters of anomaly element assemble reflected that in this area oil-gas fields might exist in the depth again. Anomaly abundance of elements exceeds regulation standard value of surface soil environment. The author considered that F, Sr, Mo, MgO, V, Th, La, U, Ti and Mn may result in harmfulness to agriculture and human health and circled pollution ranges.
