The results of this study indicate that the extended exposure period that favored inflow of meteoric waters in the UL under humid climate is favorable for promoting micrite stabilization and porosity preservation in microporous reservoirs and constitutes a key phase in the diagenetic evolution of the microporous limestone. Article history received:. Journal of Alloys and Compounds. Sonzogni and L. Ages for samples from La Nesque and Rustrel are Progress in Biological Chirality. Single calcite crystals display an optical property called birefringence double refraction. The Mohs scale of mineral hardness , based on scratch hardness comparison , defines value 3 as "calcite".


Geology ; 46 3 : — In such deposits, assessing the exact timing of reservoir property stabilization is critical to better understand the postdepositional processes favorable to the creation or preservation of porosity. However, placing reliable and accurate chronological constraints on the formation of microporosity in these reservoirs is a major challenge. In this study we performed absolute U-Pb dating of calcite cements occurring in the Urgonian microporous limestone northern Tethys margin of southeastern France. U-Pb ages ranging between Our results show that 1 the mineralogical stabilization process responsible for the formation of an excellent pervasive microporous network took place relatively early, and 2 the so-acquired reservoir quality was preserved for more than 90 m. These observations emphasize the importance of long exposure periods and associated meteoric influx for the formation and preservation of good microporous reservoirs. Establishing the relative chronology of diagenetic transformation paragenesis from thin section petrography is of outmost importance but it is not sufficient to link the evolution of petrophysical properties in reservoirs with basin-scale structural and burial events in a proper temporal framework. Prior studies have shown the importance of absolute dating of diagenetic cements, which may lead to major reinterpretation of the thermal history and the potential timing of oil generation, migration, and accumulation Mark et al. More specifically, the determination of absolute ages of diagenetic events such as micrite stabilization or massive low-Mg calcite cementation in relation to burial history and sea-level fluctuations would greatly improve our ability to constrain the overall reservoir evolution and the key processes preserving or enhancing reservoir quality in microporous carbonates.
