1 百色盆地油气成矿元素背景值及异常下限和浓度分带的确定1.1 确定方法1.1.1 背景值的确定方法 油气化探工作中背景值的确定方法,目前还在探索之中,多数赞同A.B.Vistelins(1960)等提出的观点,即经历单一地质地球化学过程的地质体,其化学元素分布形式服从正态分布,而经历多次地质地球化学作用的地质体,其化学元素含量往往不服从正态分布。在通常情况
1 Baise Basin oil and gas elemental background value and determination of the lower limit of anomalous concentration and concentration of 1.1 Determination of 1.1.1 Determination of the background value Determination of the background value of oil and gas exploration work is still under exploration and most agree with AB Vistelins (1960) put forward the view that geological bodies that undergo a single geochemical geochemical process have a normal distribution of chemical element distribution, and geological bodies that undergo multiple geochemical geochemical processes often do not conform to the positive State distribution. In normal circumstances
