The Tetouan clays have medium to low CEC and medium SSA values. The main oxides in the clayey samples are SiO2 (35 - 54.3 wt%), Al2O3 (20.6 - 43.9 wt%), and Fe2O3 (9.7 - 22.4 wt%). Geologic definition, of, relating to, or based on geology.

Geology, the fields of study concerned with the solid Earth. Included are sciences such as mineralogy, geodesy, and stratigraphy. An introduction to the geochemical and geophysical sciences logically begins with mineralogy, because Earth’s rocks are composed of minerals—inorganic elements or

per cent = |$\frac{CEC}{CEC_0}$|⁠, with CEC 0 = 80−100 meq g –1 being the CEC of pure smectite (Lévy et al. 2018). Since AL-NA-NTT1 is located inside the block, it has been less exposed to leaching than AL "I've always been afraid of face care due to lack of understanding and feeling overwhelmed by all the varieties and variables. Geologie has made it sooo simple and my face is extremely grateful! Easy to use, great customer service, and immediate results. My face just feels younger.

However, the losses of silica and alkaline earth, while the alumina level increases could explain the drop in the SiO 2 /Al 2 O 3 ratio from yellowish-brown soil to red soil.
