The Exquisite Comparison of Shale Mineralogical-Geochemical Characteristics between Chang 7 Member and Chang 9 Member in Yanchang Formation, Ordos Basin

Figure 10

The resolution comparison of reducing environmental exquisite changes for variety of parameters. The parameters of (Cu+Mo)/Zn and Cr/Cu show higher sensitivity. (Cu+Mo)/Zn and Cr/Cu values are generally much larger and smaller, respectively, for C7-3SM shale.
