in some cases the grains display well rounded
shapes, usually ellipsoidal, although spherical ones are not seldom, and show
some large spaces between them,
Dissolution
Because of their high mobility, carbonates may dissolve from horizons in which they originally accumulated, as a reaction to climatic changes towards a higher humidity.
Some of the most common indications of dissolution and remobilization of previously accumulated carbonates are:
in some cases the grains display well rounded
shapes, usually ellipsoidal, although spherical ones are not seldom, and show
some large spaces between them,
the most distintive feature however of this
process is the presence of grains with cone like terminations. The carbonate
grains exhibit numerous very pronounced denticulations as a result of dissolution.
