and subsequent retrograde dissolution in Qixia Formation, West Sichuan: a case study of incomplete and halfway-back dolomitization
4d) suggests a decrease in the content of iron minerals during dolomitization
of carbonate rocks and redistribution of iron minerals during dolomite cementation of siliciclastic rocks (Fig.
is evident in the Ordovician Tyndall Limestone (Red River Group, Selkirk Formation).
These forward-looking statements include the statements that: this well will test an identified primary objective in the Devonian Wabamun formation at a depth of approximately 2800 metres (9180 feet); Dolomitization
of the Wabamun is clearly associated with faulting at Saddle Hills and it is expected the case will be the same at Woking; and this prospect is one of the Company's high-impact exploration projects, and has significant production and reserves potential similar to that of Saddle Hills.
Dissolution porosity and late diagenetic dolomitization
may have enhanced the secondary porosity to a greater level.
Kiipli (1983) noted a link between the dolomitization
of the Pae Member (and occasionally lithologies below and above) and fracture zones.
and Limestone Diagenesis: a symposium.
The OS layers have only locally slightly changed in the diagenetic processes, whereas the barren limestone interlayers are strongly enriched with MgO and depleted of CaO that is caused by diagenetic dolomitization
in the Lower Silurian La Vieille Formation in northern New Brunswick: geological context and significance for hydrocarbon exploration.
The dolomite crystals are may be formed either due to marine environment changing from deep to shallow water with increasing salinity (Murray, 2007; Folk and Lands, 1975), or may owe to secondary diagenetic processes of dolomitization
initiated shortly after the deposition (Wenk and Bulakh, 2008; Al-Aasm,2003; Baker and Kastiner 1988).

In the assemblage of diagenetic mineralization, in addition to calcite precipitation also dolomitization
has been observed (Iueesment et al.
