What Is Isomorphous Substitution In A Clay Mineral? |
|
Answer» It is the process that SUBSTITUTES one atom for another in the structure of clay minerals at the time the clay minerals form. This LEADS to net negative charge in the mineral. Examples are the SUBSTITUTION of AL3+ for Si4+ in the tetrahedra and Mg2+, Fe2+, FE3+, and others for Al3+ in octahedra within clay minerals.
