The mineral compositions are expressed as follows: C = chlorite; I = illite; S = smectite; Na-F = albite; I/S = illite and smectite mixed layer; K = kaolinite; K-F = kaolinite and potash feldspar mixed layer; Q = quartz crystal; I/C = illite and chlorite mixed layer; C/S = chlorite and smectite mixed layer.
According to the design criterion [8-10], the highest temperature in the engineered barrier system ought not to exceed 100[degrees]C because the smectite may undergo a mineralogical alteration exposed to alkaline/salt pore fluids at high temperature [11-14].
(2015) studied the evolution of the mechanical properties of kaolinite-smectite mixtures and showed that the compression index, the swelling index and the friction angle were highly dependent on the smectite amount; Hattab et al.
A small amount of smectite is found in interlayers, denoting the presence of few swelling clay minerals.

* Note: K-Kaolinite, C-Chlorite, I-Illite, S-Smectite, I/S-illite smectite mixed layer, %S-the content of smectite in mixed-layer minerals of illite and smectite.
Smectite, illite, chlorite, kaolinite, palygorskite, sepiolite and mixed-layer illite-smectite are the common minerals found in the geological deposits.
The release of NEK from illite, vermiculite and smectite may increase the availability of K, while fixation of K ions by smectite, vermiculite and illite decreases its availability (Najafi Ghiri et al.
Tenders are invited for Modeling of the behaviour of Engineer Barrier System (EBS) in Deep Geological Disposal System (DGDS) and study of Thermo-Mechanical-Hydraulic (TMH) effects on Smectite clay in DGDS and to develop a model to optimise the engineered clay buffers (A conceptual model and design of the test system to study the Smectite clay behaviour)".
Investigators who were trying to improve drug delivery using a type of clay--spray-dried smectite clay particles, to be exact--discovered that it has "a unique ability to 'soak up' fat droplets in the gut," according to a statement from the University of South Australia, Adelaide.
During eogenesis, the Chichali and Lumshiwal formation have experienced mechanical compaction; chemical dissolution of the unstable grains, formation of smectite and illite (Figs.
Smectite, illite, and chlorite mainly form under alkaline conditions, and kaolinite mainly forms under acidic conditions [23].
