Basalt Rock: Mineral Composition and Carbonate Precipitation

The CarbFix project initiated the injection of ______ in January 2012

It was observed that > 95% of the injected ______ mineralized within a couple of months of the initial injection

Basalt is a type of rock containing abundance of minerals such as olivine and ______ which are rich in Ca, Mg, and Fe bearings

The total C ­ O2 storage capacity in ______ from the deepsea can be as high as ~ 13800 to 127800 Gt

Basalt-CO2 reaction can occur ______

Two hundred thirty tons of ­CO2 was co-injected with 7000t of ­______ into the targeted basalt formation

The experimental basalt was composed of ______, plagioclase, magnetite, olivine, chlorophaeite, and glass.

During the model calibration, it was found that ______ is very critical to match the rapid decline of pH.

Clinopyroxene is usually composed of ______ and hedenbergite.

Albite, anorthite, and k-feldspar were set to represent ______, glass, and other minerals.

The ratio Ca:Na = 0.016484:0.00665 of the Ca ______ in the original basalt specimens was kept for anorthite and albite.

The location of the Mandla lobe is in the eastern ______ volcanic province.

To validate the simulation model with the experimental results, the major source of uncertainty comes from the mineral reaction kinetic parameters including kinetic constants at 25℃, activation energy, and reactive surface area. The mineral reaction kinetic parameters of the major primary and secondary minerals were obtained by adjusting the aqueous pH of the model to fit the experimental results; these are listed in Table 1.To accelerate the ­CO2-rock reaction rate, the experiments is conventionally conducted at stirring condition which will enhance the gaseous and aqueous diffusion rate, but not impact the ______ reaction kinetics.

As a result, the aqueous diffusion coefficient was enhanced into two orders of magnitude larger than the 7.5 × ­10−9 ­m2/s (Cadogan et al 2014).Field‑scale model establishment It was mentioned previously that the fourth lava flow of the eastern Deccan basalt shows columnar and jointed structures and the uppermost part of which is highly vesicular which can provide structural pathways for ­______.The forth lava flow was selected as the target ­______ storage site. Because some of the specific properties related to ­______ storage efficiency are not available for this formation, some approximate data were employed.
