T43C-1647 The EarthChem Deep Lithosphere Dataset:Digital Access to Mantle Xenolith Petrological Data

The EarthChem Deep Lithosphere Dataset:Digital Access to Mantle Xenolith Petrological Data

:

Establishment of a geologic framework for the USArray mission of EarthScope largely depends on community efforts that facilitate the integration of seismic data with petrologic, gravity, structural, and other geologic data.

Geoframe Focus Areas from Tikoff et al. (EOS June 6, 2006)

In an effort to address the needs of the GeoFrame/USArray community, EarthChem is developing the Deep Lithosphere Petrological Dataset to provide easy access to an integrated, comprehensive, global set of petrological data from upper mantle and lower crustal rocks.

The initial focus for EarthChem’s Deep Lithosphere dataset is xenolith data from geographic locations identified by GeoFrame as relevant to the USArray mission.

HOW CAN THE COMMUNITY HELP?

• Contribute datasets and associated metadata

• Preserve collections by registering samples (www.geosamples.org)

• Provide accurate geospatial coordinates of xenolith locations

• Make recommendations that will improve the database

• Provide feedback on how the database can be improved

• Tell others!
