Testing the impact of diagenesis on the delta O-18 and delta C-13 of benthic foraminiferal calcite from a sediment burial depth transect in the equatorial Pacific [PDF]
, 2013 Stable oxygen and carbon isotope (δ18O and δ13C) values measured in foraminiferal calcite are one of the primary tools used in paleoceanography. Diagenetic recrystallisation of foraminiferal calcite can act to reset primary isotopic values but its ...

Fluid evolution in CM carbonaceous chondrites tracked through the oxygen isotopic compositions of carbonates [PDF]
, 2017 The oxygen isotopic compositions of calcite grains in four CM carbonaceous chondrites have been determined by NanoSIMS, and results reveal that aqueous solutions evolved in a similar manner between parent body regions with different intensities of ...

Refining the interpretation of lacustrine carbonate isotope records: Implications of a mineralogy-specific Lake Van case study [PDF]
, 2019 Oxygen and carbon isotope (δ18O and δ13C) data from bulk carbonates are widely applied proxies for temperature, the precipitation/evaporation ratio and productivity in lacustrine palaeohydrology and palaeoclimatology. In case of the terminal and alkaline

Assessment of crystallographic influence on material properties of calcite brachiopods [PDF]
, 2008 Calcium carbonate biominerals are frequently analysed in materials science due to their abundance, diversity and unique material properties. Aragonite nacre is intensively studied, but less information is available about the material properties of ...

Improvement of post-nickel mining soil fertility with biochar and calcite
Journal of Degraded and Mining Lands Management, 2022 Reclamation of post-nickel mining soil requires a long process and renewable innovations to improve soil properties. One of the alternative technologies for post-mining soil reclamation is utilizing oil palm empty fruit bunches (OEFB) as biochar and ...

Correlation of the entrainment factor with frother types and their mixtures in the column flotation
Cumhuriyet Science Journal, 2019 In flotation, entrainment is a mechanical mass transfer process and itis based on the changes depending on the establishment of linear relationshipbetween water and solid recovery. The present paper presents results obtainedin investigating the effect of

Mg/Ca ratios in freshwater microbial carbonates: Thermodynamic, kinetic and vital effects [PDF]
, 2014 The ratio of magnesium to calcium (Mg/Ca) in carbonate minerals in an abiotic setting is conventionally assumed to be predominantly controlled by (Mg/Ca)solution and a temperature dependant partition coefficient. This temperature dependence suggests that
