Here, we present the detailed chemical and spectral characteristics of gypsum‐phyllosilicate association of Karai Shale Formation in Tiruchirapalli region of the Cauvery Basin in South India. In 1763, when he was just 20 years old, he began collecting samples of gypsum while carrying out geological surveys in the Paris region. **Percentages are listed in weight by weight percentage (w/w%) for liquid and solid ingredients. Scanning electron microscopy (SEM) analysis in combination with an energy dispersive X-ray analyzer (EDXRA) has been used to study microfabrics of soils with gypsum, after gold-metallization, as well for chemical analysis (Herrero, 1987; Poch, 1992). Vieillefon (1977, 1978, 1979) in comprehensive studies on the improvement of analytical methods for gypsiferous soils, deals especially with the effects of gypsum on particle-size distribution.
