These sutured surfaces are the result of pressure - solution effects . The stylolite
seams thụs constitute a sequence of sutured rows . These rows may extend over
a length of few millimeter to as much as many meters . Similarly the sutured ...

Detailed study of the origin of calcareous cement is beyond the scope of present
work . However , briefly , writcrs suggest that it is the result of saturation of water
caused by an increase in the activity of carbonate ions . Regarding hematite ( ? )
