TY - RPRT T1 - Experiments Summarizing the Potential of CO2 Sequestration in the Basalts of Massachusetts – Final Report Y1 - 2011 A1 - Petrick, Carrie A1 - Stephen B Mabee KW - #MGSPub KW - #MGSPubs KW - #Reports KW - basalts KW - Carbon KW - carbonate KW - climate change KW - CO2 KW - Holyoke Basalt KW - injection KW - mineralization KW - precipitation KW - sequestration AB - Basalts are gaining more attention as reservoirs for the geological sequestration of carbon dioxide (CO2). The purpose of this report is to present the results of experiments that were conducted on the basalts in western Massachusetts and Connecticut to determine their potential to sequester CO2. There were two primary objectives of these experiments:
  • To recreate and validate prior carbonate mineralization experiments conducted on the Holyoke basalt by Schaef et al. (2009) from Pacific Northwest National Laboratories (PNNL) and to test if their results are reproducible and geographically consistent within western Massachusetts and Connecticut, and,
  • 2. To explore the possibility of reacting CO2 with basalt at the earth’s surface in an ex-situ mineral reactor and, in particular, to identify the optimum conditions necessary to precipitate large amounts of carbonate at the surface in a short time period by varying pressure, temperature, water volume, mass of sample and grain size in the experiments.

The formation occurs as thin 10-20 cm wide lenses extending from 0.5 to 6 meters in length. They are found most commonly along a 200 to 250 meter section of the shore in the intertidal zone. The intact lenses trend northeast at about 25° to 35° and dip at 61° to 75°. The material occurs in a variety of forms. These include hematite and clay rich botyoidal (grape-like) surfaces, as iron hardpan cementing together gravel and pebble-sized stones, and as 1-2 cm wide pisolites (concentrically layered round structures).
