The clay mineralogy and major element geochemistry of four distinct layers within the Cretaceous/Tertiary (K/T) boundary marl (i.e., II, IIIa, IIIb, and IV) at Stevns Klint, Denmark, including 搃mpact ...
Effects of Relative Humidity on the Basal Expansion of Mg-Smectite Equilibrated with Ethylene Glycol at Low Vapor Pressure
Basal expansion Ethylene glycol Relative humidity Smectite X-ray powder expansion
2012/1/6
The effects of relative humidity (RH) on the expansion of Mg-smectite, equilibrated with low vapor pressure of ethylene glycol (EG), was studied. Four smectite samples were equilibrated with EG vapor ...
