Siderite cement interpretation

Application of quantitative back-scattered electron image analysis in isotope interpretation of siderite cement ... 

Carothers, 1992 Spiro et al., 1993 Morad et a ., 1994), The mineral is most suitable for the study of pore-water evolution during sediment subsidence because, unlike other carbonate minerals, siderite probably does not undergo recrystallization and isotope re-equilibration during burial diagenesis, as it has no unstable precursors or polymorphs (Curtis etai, 1975 Gautier, 1982 Pearson, 1985 Curtis Coleman, 1986). Therefore, stable isotope data of siderite cements can provide a powerful tool for the interpretation of diagenetic events in geological... 

Fig. 17. Generalized paragenetic sequence for the Tirrawarra Sandstone in the Fly Lake-Moorari area. Cooper basin. The interpretation is based on the integration of petrographic, isotope and fluid inclusions results. The estimated timing of oil generation and migration is indicated (shaded zone). S1, early generation of siderite cement S2, middle generation of siderite cement S3, late generation of siderite cement D1 and D2, first and second phases of siderite dissolution, respectively.
