Dolomitization in basinal limestones of the Lagonegro Units: from early diagenesis to tectonically-driven fluid flow [PDF]
, 2011 The Triassic pelagic carbonates of the Lagonegro Basin Units from the Southern Apennines fold and thrust belt (Italy) are often replaced by dolomites, which in some cases show fabric and petrographic characteristics typical of late burial saddle ...

Dolomitization Processes in Hydrocarbon Reservoirs: Insight from Geothermometry Using Clumped Isotopes [PDF]
, 2015 Clumped isotopes geothermometry was applied to two dolomitic hydrocarbon reservoirs. Results indicate that late burial dolomitization occurred at ~110°C in the Albian Pinda dolostone (offshore Angola) and ~90°C in the Mano-Meillon dolostone (Aquitaine ...
