Basalt formations are prevalent in the Big Sky region, and while less studied than other potential storage sites for CO2, they may play an important role in geologic sequestration due to their unique geochemical and physical properties. Regionally, basalts offer significant long-term storage potential estimated in the range of 33-134 billion metric tons. These estimates scaled globally suggest that the five largest basalt provinces could sequester 10,000 years of the world’s CO2 emissions. Basalt provinces are globally distributed and could significantly expand CO2 storage options in regions where conventional storage is limited or non-existent.
BSCSP and Idaho State University developed a national Mafic Atlas to assess the sequestration potential of basalts through modeling studies, laboratory testing, and insights developed from mafic rock pilot projects. The Mafic Atlas online mapping application highlights the Columbia River Basalt Group in Washington and Oregon and its proximity to the West Coast power load. Features of the map include:

As part of our Phase II project, the Columbia River Basalt Group (CRBG) has been extensively studied. To date, an extensive knowledge base has been created, including numerous laboratory experiments, a first of its kind seismic survey, and baseline surveys to further the understanding of carbon sequestration in basalts. The BSCSP is conducting a small scale pilot test to expand laboratory findings to in-situ environments. Visit our projects page to learn more about basalt research in the BSCSP.

The Mafic Atlas interactive map was developed using ESRI ArcGIS Server 10.1 and the ArcGIS Viewer for Silverlight. This software package enables organizations to use web-oriented spatial data services to produce internet-based mapping interfaces. BSCSP will continue to increase the functionality of the interactive map by developing geo-processing capabilities and updating the user interface functionality.
