Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/ds/414 Description: Abstract: This database provides information on the occurrence of ultramafic rocks in the conterminous United States that are suitable for sequestering captured carbon dioxide (CO2) in mineral form, also known as mineral CO2 sequestration. Data are compiled from varied-scale geologic maps and target only magnesium-silicate ultramafic rocks, which typically consist primarily of olivine- and serpentine-rich rocks. Mineral CO2 sequestration is a proposed greenhouse gas mitigation technology whereby CO2 is disposed of by binding it with calcium or magnesium to form a solid magnesium or calcium carbonate product. The reaction offers virtually unlimited capacity to permanently store CO2 in an environmentally benign form via a process that takes little effort to either verify or monitor. The magnesium-silicate bedrock available to sequester CO2 was evaluated by researchers at Columbia University and the U.S. Geological Survey. The resulting digital database details locations throughout the conterminous United States where ultramafic minerals potentially suitable for mineral CO2 sequestration are found. Purpose: This map shows areas of ultramafic rocks in the conterminous United States that are potentially suitable for mineral CO2 sequestration. These data were compiled to better characterize the national mineral resource base for a mineral CO2 sequestration process. Other potential uses of these data include (1) targeting sites for more detailed study, and (2) identifying locations for pilot or industrial scale projects.

Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.3.0.1770 Data_Quality_Information: Logical_Consistency_Report: Lines forming polygons join at endpoints to completely enclose defined areas. No duplicate polygon features or pseudo nodes exist. Nodes are represented by a single coordinate pair that indicates the starting and (or) ending point of the line forming the polygon. All vertices that define the shapes of the polygons are represented by unique coordinate pairs. Completeness_Report: Polygon features representing ultramafic rocks were selectively compiled from digital bedrock geology maps of the U.S.A. and individual States. The data set is complete and is not anticipated to change. Lineage: Process_Step: Process_Description: Polygon features representing ultramafic rock units in the conterminous United States were extracted and compiled from 30 digital geologic maps and digitized from 11 paper maps ranging in scale from 1:50,000 to 1:750,000. Ultramafic rock types were selected using queries and rock identification information in attribute tables. Seventeen additional paper maps were used to confirm the accuracy of some source maps, clarify the mineralogical makeup of rock units, and provide higher resolution data for some areas. Full references for these maps are provided in “table 2” and the "References Cited" section of the report (DS414_text_508.pdf). Process_Date: 2008 Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal accuracy of the polygon features in the data set is based upon the accuracy of the original source maps. The original source maps generally meet the National Map Accuracy Standards, which states that 90 percent or more of polygon features represented on the map are within a stated horizontal distance of their actual ground location. The acceptable horizontal distance is 12.2 meters for 1:100,000-scale maps; 127 meters for 1:250,000-scale maps; and 254 meters for 1:500,000-scale maps.
