摘要

Mitigating climate change requires transformational advances for carbon dioxide removal,including geologic carbon sequestration in reactive subsurface environments.The Wallula Basalt Carbon Storage Pilot Project demonstrated that CO2 injected into>800 m deep Columbia River Basalt Group flow top reservoirs mineralizes on month-year timescales.Herein,we present new optical petrography,micro-computed X-ray tomography,and electron microscopy results obtained from sidewall cores collected two years after CO2 injection.As no other anthropogenic carbonates from geologic carbon storage field studies have been recovered,this world-unique sample suite provides unparalleled insight for subsurface carbon mineralization products and paragenesis.Chemically zoned nodules with Ca/Mn-rich cores and Fe-dominant outer rims are prominent examples of the neoformed carbonate assemblages with ankerite-siderite compositions and exotic divalent cation correlations.Paragenetic insights for the timing of aragonite,silica,and fibrous zeolites are clarified based on mineral texture and spatial relationships,along with time-resolved downhole fluid sampling.Collectively,these results clarify the mineralogy,chemistry,and paragenesis of carbon mineralization,providing insight into the ultimate fate and transport of CO2 in reactive mafic-ultramafic reservoirs.
