value indicates that the KIE due to calcite growth results in lower Δ 47 values, especially at lower temperatures (Figure 4e). The negative Δ 47 fractionation associated with KIE is consistent with observation of natural carbonates in previous studies (Herlambang & John, 2021; Loyd et al., 2016; Thiagarajan et al., 2020). For example, modern seep carbonates exhibit anomalously low Δ 47 values, possibly due to rapid carbonate precipitation (Loyd et al., 2016; Thiagarajan et al., 2020).…”

“…de Winter et al (2021) found that the chalky microstructures of the oyster shells with high growth rates show lower Δ 47 values compared with the foliated microstructure with low growth rates. Herlambang and John (2021) applied trace-element partitioning in constraining the precipitation rate of natural calcites and found that samples with higher precipitation rates have lower Δ 47 values. Provided that the variation of Δ 47 values in their macro-columnar calcites was controlled primarily by KIE during calcite growth, the highest magnitude of Δ 47 fractionation would be ∼0.05‰, broadly comparable with the range of KFFs determined in our study (Figure 4e).…”

Carbonate clumped isotope (Δ 47 ) thermometry is based on the temperature-dependent bonding of 13 C and 18 O within the lattice of carbonate minerals relative to that expected when all isotopes are randomly distributed (Ghosh et al., 2006;Schauble et al., 2006). The clumped isotope geochemistry of carbonates provides a singlephase geothermometer independent of the stable isotopic composition of the parent fluid, and is a frontier in the development of paleo-temperature proxies (Eiler, 2007(Eiler, , 2011. The last decade has seen an increasing use of clumped isotopes in studies of climate change on various geological time scales (

“…Higher rates of precipitation at temperatures <50°C (for example, during degassing) may potentially cause kinetic fractionation and isotopic disequilibrium. A higher precipitation rate correlates with increasing clumped isotope temperatures and heavier calculated fluid δ 18 O (Defliese & Lohmann, 2016; Herlambang & John, 2021). At equilibrium, Δ 47 values should be independent of the δ 18 O of the fluid.…”

Calcite‐cemented concretions in non‐marine sandstones: An integrated study of outcrop sedimentology, petrography and clumped isotopes

et al. 2023

Calcite‐cemented concretions can reduce reservoir quality and form important low‐permeability baffles for fluid flow in sandstone hydrocarbon carrier beds/reservoirs. Understanding the origin and distribution patterns of concretions has important implications for characterizing reservoir heterogeneity and developing fields. The origin of calcite concretions in non‐marine sandstones lacking detrital carbonate to source the cement is poorly studied. The practical difficulty of obtaining the precipitation temperature of the concretions prevents the precise determination of the source of cement components, solute flux, pore water type and the geochemical microenvironments in which cement precipitated. Carbonate clumped isotope thermometry can give unique constraints to the temperature of concretionary cement precipitation. This study focused on outcrops of the Lower Cretaceous non‐marine Qingshuihe Formation in the Urho area, on the north‐western margin of the Junggar Basin (West China). Four depositional facies associations were recognized, corresponding to channel, mid‐channel bar, abandoned channel and overbank floodplain environments. Calcite concretions occur only in sandstones and include spherical, ellipsoidal and tabular forms. They are isolated and/or mutually aligned in layers that tend to be either at the top, base, or within channel and mid‐channel sand bodies. The clumped isotope temperatures for the concretionary calcite range from 31 to 45°C with a standard error of <3°C. The calcite has highly variable, low δ13C values ranging from −16.91 ± 0.01 to −2.93 ± 0.02‰ (Vienna Pee Dee Belemnite). The 13C‐depleted bicarbonate source was linked to biodegradation of migrated oils at shallow burial owing to tectonic uplift and erosion. Calcite δ18O values are very consistent and fall between −12.30 ± 0.04 to −9.79 ± 0.31‰ (Vienna Pee Dee Belemnite). Introduction of meteoric water was a dominant mechanism for the pronounced 18O‐depletion in the oxygen isotopes of pore water, along with water–rock interaction during alteration of volcaniclastic materials in sandstones. Meteoric groundwater flushed the Qingshuihe sandstones as confined aquifers down the regional palaeo‐slope, biodegrading the migrated oils and enabling a sufficient solute flux for precipitation of concretions.

“…Similarly, Wagner et al (2010) used REEs to show that veins from the Rhenish Massif (Germany) formed from advecting fluids which leached the wall rocks, which was reflected in vein mineral trace element signatures. Herlambang and John (2021) paired trace element (Fe and Mn) concentrations with clumped isotope palaeothermometry in calcite veins from Jebel Madar, Oman, and found a strong correlation between trace element concentration and clumped isotope temperature. This indicated variable calcite crystal growth rates, causing potential kinetic fractionation in clumped isotopes.…”

Application of geochemical proxies to vein minerals - particularly calcite - can fingerprint the source of fluids controlling various important geological processes from seismicity to geothermal systems. Determining fluid source, e.g. meteoric, marine, magmatic or metamorphic waters, can be challenging when using only trace elements and stable isotopes as different fluids can have overlapping geochemical characteristics, such as δ18O. In this contribution we show that by combining the recently developed LA-ICP-MS U-Pb calcite geochronometer with stable isotopes (including clumped isotope palaeothermometry) and trace element analysis, the fluid source of veins can be more readily determined. Calcite veins hosted in the Devonian Montrose Volcanic Formation at Lunan Bay in the Midland Valley Terrane of Central Scotland were used as a case study. δD values of fluid inclusions in the calcite, and parent fluid δ18O values reconstructed from clumped isotope palaeothermometry, gave values which could represent a range of fluid sources: metamorphic or magmatic fluids, or surface waters which had undergone much fluid-rock interaction. Trace elements showed no particularly distinctive patterns. LA-ICP-MS U-Pb dating determined the vein calcite precipitation age – 318±30 Ma – indicating a metamorphic or magmatic fluid source was unlikely as there was no metamorphic or magmatic activity was occurring in the area at this time. The vein fluid source was therefore interpreted to be a surface water (meteoric based on paleogeographic reconstruction) which had undergone significant water-rock interaction. This study highlights the importance of combining the recently developed LA-ICP-MS U-Pb calcite geochronometer with stable isotopes and trace elements to help determine fluid sources of veins, and indeed any geological feature where calcite precipitated from a fluid that may have resided in the crust for a period of time (e.g. fault precipitates or cements).
