Thermally driven diagenesis, which would cause extensive loss of greigite at these depths, does not appear to be significant here. Multidomain magnetite grains dominate the magnetic mineralogy in the deepest part of the sequence, but some single-domain magnetite survives as inclusions in silicates. Fluid anomalies representing sulfate influx drive locally renewed greigite authigenesis, as do methane and ethane accumulations. In some cases, where methane is accompanied by H₂S ("sour gas"), fine-grained greigite is converted to pyrite. We term these multiple episodes of enhanced magnetic mineral alteration "punctuated magnetic mineral diagenesis." Despite both progressive and punctuated magnetic mineral diagenesis, enough depositional remanence survives to allow recognition of the magnetostratigraphy to 1,320 m below seafloor.]]> Thu 30 Jan 2020 16:34:09 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:1767 Sat 24 Mar 2018 08:27:37 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:355 Sat 24 Mar 2018 07:42:36 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27745 -1s^-1 for sulfate and vanadate, respectively. Their application to PCC was further investigated by simulating the effect of these catalysts on the absorption process under PCC operating conditions. Vanadate was confirmed to have a greater efficiency toward CO₂ hydration than sulfate and also a series of other inorganic catalysts reported earlier.]]> Sat 24 Mar 2018 07:27:45 AEDT ]]>
