The Late Eocene Ergeliin Zoo Formation, Mongolia, was subdivided into four facies associations/stratigraphic units which
are characterized by various carbonate minerals: (I) mud–sand flat (low-Fe dol...
Change in Layer Charge of Smectites and Smectite Layers in Illite/Smectite during Diagenetic Alteration
Beidellitization Charge Location Diagenesis Greene-Kelly Test Illite/Smectite Layer Charge Smectite
