摘要
海兴小山地区浅部为巨厚未固结的第四系河湖相松散沉积物,火山岩零星发育,多为玄武岩类。火山岩岩体力学性质稳定,可作为核电站大型基建工程的有效承载层。因此,本次采用地面高精度磁法勘察,有效地圈定了磁异常分布范围,推断解释了浅层火山岩的性质,经钻孔验证有效揭露到了浅层玄武岩。
The shallow part of Xiaoshan area in Haixing is quaternary lacustrine unconsolidated thick loose sediments.Volcano rocks develop sporadically in this area,and they are mostly basalt.Mass properties of volcano rock is in stability,and it can be used as effective bearing layer of one large nuclear construction.Therefore,the use of ground high precision magnetic survey can delineate anomaly distribution of magnetic range effectively,infer and interpreter the properties of shallow volcano rock,so that the shallow basalt is discovered in hole drilling.
