The evidence he presented that changed my mind about this was the distribution pattern of rare earth elements found in the clay body and slip.
Depending on whether this difference is related to the elements' presence in the clay matrix or inclusions, we would interpret it differently.
Presence of chromium was reported (0.49% of the total elements) on the clay chips after treatment with chromium (VI).
This brand of clay also comes in a beautiful selection of colors, including two transparent clays, six "stone" textured clays, a glow-in-the-dark clay, and metallic colored clay ("perglantz").
One of the important factors controlling the rate of dissolution is the concentration in the aquatic medium of the elements extracted from the clay mineral.
"The clay rock has such power of retention that if there were to be any release from the canister at any phase of the storage period, the radioactive elements would also be trapped on the surface of the minerals in the clay".
Structure elements in the natric horizon may be covered by thick, dark cutans of clay and/or translocated organic matter, especially if the soil reaction is strongly alkaline.
In the clay layer there were no forams.
In natural clays, substitutions in the clay framework (Si for Al and Al for Mg) are commonly found; as a result, charge-balancing counterions, such as Na+ and Ca2+, reside between the clay sheets.
In this study, we consider the archetypical swelling clay, montmorillonite (MMT), which possesses a negative charge due to isomorphic substitutions in the clay framework.
