have been observed (Fig.
Deposition, diagenesis and dolomitization
of Neogene Seroe Domi Formation coral reef limestones on Curacao, Netherlands Antilles: Foundation for Scientific Research in the Caribbean Region.
Some of the diagenetic processes were also observed in the formation, including compaction, cementation, dolomitization
The ooid grains feature diagenetic replacive dolomitization
and dissolution vugs.
The process of dolomitization
has largely destroyed primary textures as well as fossils.
Carbonate diagenesis includes such major processes as cementation, microbial micritization, neomorphism, dissolution, compaction, and dolomitization
and it operates in three main environments: marine, near-surface meteoritic, and burial (Tucker & Wright 1994).
The mineralization process (ore development, calcitization, dolomitization
and silification) resulted in the higher toughness of the rocks and in the lower porosity and absorbability.
Ore in the Los Lamentos district is associated with dolomitization
of limestone, the dolomite forming aureoles averaging 15 meters in thickness which in some cases surround the ore.
However, heterogeneities in the substrate, made by bioturbating infauna, may play a more important role in dolomitization
than has been previously considered.
Four phases of dolomitization
are recognized at Lisheen.
of the Wabamun is clearly associated with faulting at Saddle Hills and it is expected the case will be the same at Woking.
Grain fracture porosity and dolomitization
may have been resulted into an increase in secondary porosity and thus adds to the reservoir potential ofthe Chichali Formation.
