The colour of the gypsum is normally greyish, and in-hand specimens of the gypsum contain large and clearly visible crystals.
Interbedded shale and coal facies contain occasional desiccation cracks and locally gypsum crystals.
Similar to that of the 1993 core, the profile contained gypsum bands that reflect periods of low lake level and, hence, dry climate.
However, gypsum is not always available, it is now very expensive and its application on groundnut may not be economical.
Analysis of the photograph of the gypsum cast and the latex cast at hand indicates that the casts were made from the same specimen.
The minor internal dissolution of gypsum has an important consequence for the immediate habitat.
Wave-ripple marks are commonly observed within this facies association, and gypsum occurs locally as discontinuous laminae.
Circles represent values less than 2%, except in the gypsum zone centered on 11 m, where circles signify only the presence of pollen types.
