Two minerals differentiate the two plant regime clay assemblages: illite present in all cases but more abundant in the sequoia soils, and chlorite present in three of the more acidic soils under sequoia but not present in the corresponding prairie soils. The chlorite is identified by the sharp peak at 14.2 and 7.1 Å.

The I/S clays in the younger Barakar mudstones are more illitic and ordered (mostly 60-90% illite with R1 to R3 ordering) compared with the older Talchir mudstones (I/S clays with 40-80% illite, R0-R1 ordering), which rules out diagenetic conversion of smectite to illite/smectite with increasing burial depth.

Akasha [ 125] presented the results of research on the use of clay obtained from five locations in Libya and calcined as a partial substitute for cement. The studied clays contained from 30% to 90% of kaolinite and, besides that, mainly quartz (and in one case additionally a small amount of illite).

Kaolinite clays have long been used in the ceramic industry, especially in fine porcelains, because they can be easily molded, have a fine texture, and are white when fired. These clays are also used as a filler in making paper. In the United States, deposits are found primarily in Georgia, North Carolina, and Pennsylvania; china clay is also

As a result, the necessity for bentonitic clays or comparable alternatives to be sourced locally has become critical. 2.1 Classification of clay minerals Clay minerals are classified into different groups as follows; Kaolinite, Smectite, Vermiculite, Illite and Chlorites. Kaolinite is the purest of all clays, with little variation in composition.

Smectite and vermiculite are good examples of expanding types of crystalline silicate clay while fin grain mica is nonexpanding crystalline silicate clay. Smectite: Is a member of silicate clays in the 2:1 type which have high shrinking and swelling properties because of its interlayer expansion in dry and wet conditions [15,18].
