简介：近的表面黄土在油和煤气的区域有磁性的危险性异例，这是一个事实。这些异例为什么并且是否发生他们有任何重要价值因为油和煤气的水库的探索是地球物理学者主要被担心关于并且学习的问题。我们在油和煤气的区域分析表面黄土危险性异例的形成的原因，处理与合适的数学方法在西方的中国从油和煤气的区域拿的黄土样品的危险性的观察，并且决定黄土危险性的背景值。这些结果被用来决定油和气体基于危险性异例与一个数字评估因素勘探区域。实际油井用危险性异例验证了那显示油和煤气的水库的地点是有效的。关键词危险性-油和煤气的水库-表面黄土-并且油井第一作者邵光洲在2003从Chang鈥檃n大学在应用地球物理收到了他的M.Sc。他现在为他的博士正在学习并且在Chang鈥檃n大学里教。他出版了五份科学报纸。他的兴趣包括主要地震的探索，水库参数的倒置，和高度--精确gravity/磁性的数据处理。
