Based on the summary of geological and mineralized features of the nonferrous and precious metal deposits in the western Baoding, the article analyzes the relationship between these deposits and the two deep rooted fractures of ShangHuangqi-Wulonggou and the Zijinguan-Lingshan and the magmatite belt in NE which is controlled by the fractures. It also puts forward the opinion that the deposits within the area accumulate in the gentle-angled extruding part of complex and the acute-angled area of the intersection...

Based on the summary of geological and mineralized features of the nonferrous and precious metal deposits in the western Baoding, the article analyzes the relationship between these deposits and the two deep rooted fractures of ShangHuangqi-Wulonggou and the Zijinguan-Lingshan and the magmatite belt in NE which is controlled by the fractures. It also puts forward the opinion that the deposits within the area accumulate in the gentle-angled extruding part of complex and the acute-angled area of the intersection part of the nearly north-southward fracture and the nearly west-eastward fracture. It also analyzes the ore controlling factors in detail. The prospecting direction is pointed out for the future.

在总结保定西部地区有色金属及贵金属矿床成矿地质特征的基础上,分析了这些矿床与上黄旗—乌龙沟、紫荆关—灵山两大深大断裂以及受深大断裂控制的NE向展布的岩浆岩带的关系,提出了区内矿床集中分布于杂岩体的低角度的舌状突出部位和近SN向断裂与近EW向断裂交汇处锐角区域的观点,并对该区的控矿因素作了全面分析,指出了今后的找矿方向。

207 top soil samples were collected from Hebei province and the contents of heptachlor were measured.The concentration of heptachlor averaged 0.297 ng·g-1,with the standard deviation 0.026 ng·g-1,and fitted with typical log-normal frequency distribution with the geometric mean and standard deviation(0.118±1.113)ng·g-1.It is believed that heptachlor in the soils resulted from the agricultural applications in 1980's or earlier,and the present pollution status imposed no threat to human health in terms of food...

207 top soil samples were collected from Hebei province and the contents of heptachlor were measured.The concentration of heptachlor averaged 0.297 ng·g-1,with the standard deviation 0.026 ng·g-1,and fitted with typical log-normal frequency distribution with the geometric mean and standard deviation(0.118±1.113)ng·g-1.It is believed that heptachlor in the soils resulted from the agricultural applications in 1980's or earlier,and the present pollution status imposed no threat to human health in terms of food production.Significant differences were observed among the eleven municipal areas.The relatively higher concentrations in the soils occurred at Qinhuangdao-Tangshan zone,western Baoding,southwestern Zhangjiakou,due to the higher contents of soil organic carbon(TOC)in these areas.After normalization with soil TOC,a higher level region stretched from Qinhuangdao to Hengshui at the eastern part of Hebei Province with the highest value at Cangzhou.The historical input of heptachlor with spatial variation of concentration was likely related to the local production areas of soybean and sorghum.

在河北省境内采集207个表层土壤样品,测定其中的七氯含量。结果表明,表土中七氯含量为0.297ng·g-1±0.026ng·g-1。浓度数据呈典型的对数正态分布,几何均值及标准差为0.118ng·g-1±1.113ng·g-1,此浓度范围不会通过农作物吸收对人体健康造成影响。河北境内各市土壤中七氯含量存在显著差异。实测浓度较高的秦皇岛-唐山一带、保定西部和张家口西南部等地主要与土壤有机质含量较高有关。经土壤有机碳含量标化后,沧州土壤中七氯的浓度最高,其次为廊坊和衡水。作为20世纪80年代农业施用的残留,不同地区的浓度差异与大豆、高梁等作物的栽培面积有关。
