Abstract:
In this report we present a preliminary assessment of the
potential for CO2 disposal by sequestration in geological
settings in Nevada using analysis with geographic
information systems (GIS). The key assumptions made are
that for CO2 disposal in saline aquifers it is wisest to
(1) avoid underground disposal in areas of fractured
bedrock and restrict the assessment to parts of alluvial
basins that are thick enough to provide a seal against
leakage and have sufficient pressure to keep the CO2 in a
condensed phase; (2) stay away from active faults whose
fracture zones may allow leakage of CO2 from underground
injection sites; (3) avoid areas that in the foreseeable
future have a reasonably high probability of being explored
and developed for mineral, geothermal, or water resources;
(4) avoid current urban areas and areas that are likely to
experience significant population growth during the 21st
century; and (5) avoid restricted lands, such as parks and
military reservations. The data sets used in the GIS
analysis are made available in the electronic version of
this report, so that others may reevaluate the approach
with different assumptions and data sets.
Purpose:
In 2003, the State of California, in collaboration with the
States of Alaska, Arizona, Oregon, and Washington, asked
the State of Nevada to participate in a regional analysis
of CO2 sequestration potential, through both terrestrial
and geological approaches. The terrestrial approaches
involve growing more biomass (particularly trees), and the
geological options include proven technologies, such as
using CO2 to enhance recovery from oil fields and disposal
of CO2 in saline aquifers, and more unconventional
approaches. As the state with the least amount of annual
precipitation, Nevada has little potential for growing
substantially more biomass relative to states along the
Pacific Ocean.
In this report we present a preliminary assessment of the
potential for CO2 disposal by sequestration in geological
settings in Nevada using analysis with geographic
information systems (GIS). The key assumptions made are
that for CO2 disposal in saline aquifers it is wisest to
(1) avoid underground disposal in areas of fractured
bedrock and restrict the assessment to parts of alluvial
basins that are thick enough to provide a seal against
leakage and have sufficient pressure to keep the CO2 in a
condensed phase; (2) stay away from active faults whose
fracture zones may allow leakage of CO2 from underground
injection sites; (3) avoid areas that in the foreseeable
future have a reasonably high probability of being explored
and developed for mineral, geothermal, or water resources;
(4) avoid current urban areas and areas that are likely to
experience significant population growth during the 21st
century; and (5) avoid restricted lands, such as parks and
military reservations. The data sets used in the GIS
analysis are made available in the electronic version of
this report, so that others may reevaluate the approach
with different assumptions and data sets.

Process_Step:
Process_Description:
The mineral resources layer is a compilation of four data
sets. The first data set (Mining_Districts) is the "Mining
Districts of Nevada" 2nd edition by Tingley (1998). This is
a digital polygon coverage of mining districts in Nevada.
The second data set (NV_MRDS) is the USGS Mineral Resource Data
System (MRDS) database from "Nevada Abandoned Mines
Database Compilation Update" by Hess (2001). A subset of
MRDS data contained in this report was used as a point
coverage indicating sites that have had some type of
mineral exploration, development, or production. The
original MRDS database was created and is still maintained
by the USGS. Sand and gravel locations were removed before
these data were used.
The third data set (MILS2000) is the Mineral Inventory Lands
System (MILS) database from Hess (2001). A subset of MILS
data contained in this report was used as a point coverage
indicating sites that have had some type of mineral
exploration, development, or production. The original MILS
data base was created by the U.S. Bureau of Mines and is no
longer being updated. Sand and gravel locations were
removed before these data were used.
The fourth data set (Map_120_e) is the "Gold and silver
resources in Nevada" database by Davis and Tingley (in
press, updated from 1999). This map shows locations of
deposits with a noted or implied gold and/or silver
resource or reserve discovered since 1930. Base-metal and
industrial-mineral deposits that contain a significant
amount of gold or silver are also shown. This point
coverage was used to show locations of known precious metal
resources. Significant pre-1930 gold and silver deposits
are captured in the second and third data sets. The
second, third, and fourth data sets, all point coverages,
were plotted with a 5-km buffer, which takes into account
potential location inaccuracies, necessary space to develop
a large surface or subsurface mine, and the potential for
additional discoveries associated with the known resource.
Five kilometers is also within the effective distance of
large hydrothermal systems responsible for the formation of
most ore deposits in Nevada. Once the point coverages were
buffered, all three were combined with the mining district
coverage using the union command. Internal polygons were
dissolved by aggregating all areas that fell within a
buffer or mining district area into single polygons.
Portions of those polygons that fell outside of Nevada were
clipped to the Nevada State boundary.
