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 ...

Due to the abundance of iron oxide , the effect of oxidation can be easily seen in
these fractures . These effects are , however , less in the basal part but dominant
in the upper part . In some cases the quartz grains are totally coated by iron ...
