High-Precision Chronostratigraphic Correlation of Mid-Cretaceous Strata in Western Interior Basin,USA through Graphic Correlation Technique

摘要：

　　Graphic correlation method has been proved to be very useful in correlating sections in different places.In this study,we have selected five sections from the Western Interior Basin,USA and applied graphic correlation method to correlate them.The selected five sections are located from the eastern to the western margins of the Western Interior Basin,USA.The cross-basinal high-precision chronostratigraphic correlation provides geologists a better understanding about how facies and depositional environments evolved across the mid-Cretaceous Western Interior Basin during the mid-Cretaceous.In addition,our data fits well with the previous understandings about mid-Cretaceous Western Interior Seaway,which characterized by slow depositional rates and higher organic matter concentration.
