Lacustrine facies record cooler temperatures than the palustrine pebbly pelmicrite and mottled micrite, indicating that water depth played an important role in formation temperatures. δ 18 O water values calculated from Δ 47 values show 18 O-enrichment in the mottled micrite relative to the pelmicrite facies, implying that evaporative periods …

Apr 21, 2022 · In oil and gas industry, classifying carbonate rocks is a major step in core and thin section description. Two classification systems have been widely used in the industry: Folk (1959,1962) Classification. Dunham (1962) Classification. Both classifications provide an indication of depositional energy setting and reservoir quality.
