“…This suggests the dissolution porosity mainly occurred within the fault damage zones, although it is still ambiguous for the process of the large caves [34]. There is generally a complicated interplay between cementation and dissolution as a consequence of mechanical deformation in the Ordovician carbonates [7,13,14,53]. In this study, much more dissolution developed along the fault damage zones, suggesting fluid pathways formed in those areas facilitating the later dissolution in the fault zones.…”

“…The strong cementation of early two stages cements (C2 and C3) may correspond to a rapid subsidence following early fault activities [28][29][30]. In addition, the hydrothermal activity possible increased the calcite precipitation [48,49,51], considering the damage zone is favorable for fluid flow and mineral precipitation [5,14,17]. On the other hand, the latest fracture family (F3) is possible related to Eocene fault activity, prior to the onset of large scale cementation.…”

“…Structural diagenesis is the study of the relationships between deformation or deformational structures and chemical changes to sediments [9]. Whereas fault architecture and process can constrain the diagenesis along a fault zone, diagenetic processes can significantly influence the fault architecture, rock properties and mechanisms of brittle deformation leading to fracture or faulting [9][10][11][12][13][14][15]. Studies on the integration of fault process and structural diagenesis are helpful to understand not only the mechanisms of faulting, but also petrophysical properties and fluid flow along fault zones, promoting efforts in multidisciplinary studies of structure, reservoir characterization and diagenesis [9,[16][17][18][19][20][21][22].…”

The identification of structural diagenesis and the reconstruction of diagenetic paragenesis in fault damage zones is important for understanding fault mechanisms and fluid flow in the subsurface. Based on the examination of core and sample thin section data, we deciphered the diagenetic parasequence and their fault controls for Ordovician carbonates in the northern Tarim intracratonic basin in NW China (Halahatang area). In contrast to the uniform nature of diagenesis observed in country rocks, there is a relatively complicated style of compaction and pressure solution, multiple fracturing, and cementation and dissolution history along the carbonate fault damage zones. The relative paragenetic sequence of the structure related diagenesis suggests three cycles of fracture activities, following varied fracture enlargement and dissolution, and progressively weaker calcite cementation. These processes of structure related diagenesis are constrained to the fault damage zones, and their variation is affected by the fault activities. The results of this study suggest that the carbonate reservoir and productivity could be impacted by the structure related diagenesis locally along the fault damage zones.

BevezetésA geokémiai vizsgálatok mára a geológia minden terü -letén -az őslénytantól a rétegtanon át, a paleoklíma kutatásig -megkerülhetetlenné váltak. Az izotóp-geokémia tör té nete a XX. század első felére nyúlik vissza. Az első tömegspektrométer megalkotása 1947-ben Alfred NIER nevé hez fűződik. Ebben az időben publikálta UREY (1947), valamint BIGELEISEN & MAYER (1947 O egy többszörösen helyettesített CO 2 izotopológ). Mivel az ilyen izotopológok rendkívül alacsony előfordulási aránya a mérésüket korábban lehetetlenné tette, a többszörösen helyettesített izotopológok egészen az 1980-as évek végéig érintetlen kutatási területnek számítottak. Az első, kifejezetten erre a témára irányuló kutatás az atmoszféra metán -jának izotópos összetételét vizsgálta (MROZ et al. 1989 O isotopes within one molecule. Using the clumped isotope thermometer, the temperature of the carbonate precipitating fluids can be determined with high precision, based solely on the clumped isotope value (∆ 47 ) of carbonates. Besides palaeoclimatology, the method can be used in several research fields in geology, including palaeoceanography, atmospheric research, reservoir geology, geomorphology, structural geology, diagenesis, biogeochemistry, low temperature metamorphic processes, and meteorite research. Due to continuous developments, the number of applications is still significantly increasing. This paper briefly introduces the reader to the principles of clumped isotope geochemistry, reviewing its theoretical basis, and possible applications, and also looks at available calibrations. Furthermore, it provides an overview of the current state-of-the-art.Keywords: stable isotopes, clumped isotopes, geochemistry, thermometry, climate reconstruction, methodology Összefoglalás A kapcsoltizotóp-geokémia (clumped isotope geochemistry), egy olyan új, dinamikusan fejlődő kutatási módszer, amely a 13 C és a 18 O izotópok egy molekulán belüli kapcsolódásának hőmérsékletfüggésén alapszik. Segítségével a karbonátok kiválási hőmérséklete nagy pontossággal meghatározható, kizárólag a karbonát fázis kapcsoltizotóp-értéke (∆ 47 ) alapján. A paleoklimatológiai alkalmazások mellett a módszer a geológiai kutatások számos területén (pl. paleooceanográfia, atmoszféra-kutatás, rezervoár-geológia, geomorfológia, tektonika, diagenezis, biogeokémia, alacsony hőmérsékletű metamorf folyamatok, meteorit-kutatás, stb.) alkalmazható, és a műszerfejlesztések révén az alkal mazá -sok köre folyamatosan bővül. A cikk röviden áttekinti a kapcsolt izotópos módszert, bemutatva annak alapjait, a rendelkezésre álló kalibrációkat, a lehetséges alkalmazási területeket és a témában eddig megjelent publikációkat.

“…Carbonates are very sensitive to these fluids-rock interactions that lead to secondary processes like cementation and dissolution (Deville de Periere et al, 2017;Fournier and Borgomano, 2009;Lambert et al, 2006). Fault zones related diagenetic processes locally modifying the initial rock properties (mineralogy and porosity) and therefore their reservoir properties (Hodson et al, 2016;Knipe, 1993;Knipe et al, 1998;Laubach et al, 2010;Woodcock et al, 2007). In case of poly-phase fault zones, duplications of fluid pathways lead to even more complex diagenetic modifications.…”

Abstract. Microporous carbonate rocks form important reservoirs with high a permeability variability depending of sedimentary, structural and diagenetic factors. Carbonates are very sensitive to fluids-rock interactions that trigger to secondary processes like cementation and dissolution leading to reservoir properties modifications. As they can act as drains or barriers, fault zones influence the fluid flows in the upper part of Earth crust and increase the fluid-rock interactions. The aim of this study is to identify fault zone impact on fluid flows and reservoir properties during basin geodynamic history. The study focuses on 2 fault zones of the Eastern part of La Fare Anticlinal (SE France) where Urgonian microporous carbonates underwent polyphase tectonics and diagenesis. We took 122 samples along 4 transects cross-cutting two fault zones. Porosity values have been measured on 92 dry plugs. Diagenetic properties of samples have been determined on 92 thin sections using Polarized Light Microscopy, cathodoluminescence, red alizarin, SEM and isotopic measurements (δ13C and δ18O). Height calcite cement stages and 2 micrite micro-fabrics have been identified. This study highlight that fault zones acted as drain canalizing low temperature fluids at their onset, and induced fault zone cementation with two cementation phases, what has strongly altered and modified local reservoir properties.
