The ore deposits can exclusively be formed under the sedimentation process, such as banded iron ore formation (BIF/BHQ), diamond in kimberlite pipes and conglomerate, zinc–lead deposits in dolomite, and limestones. The deposits show bedded, stratabound, and often stratiform features having concordant relation with country rocks.
