1. 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.

The initial focus for EarthChem’s Deep Lithosphere dataset is xenolith data from geographic locations identified by GeoFrame as relevant to the USArray mission. SCIENTIFIC CONTEXT Data are compiled in a relational database that complements the data collections of NAVDAT, GEOROC, and PetDB, and which together can be accessed and downloaded through the EarthChem Portal. QUERY INTERFACE Xenolith locations currently available in the EarthChem xenoliths database. Map generated using GeoMapApp software (www.geomapapp.org) USA geolocations include: Kilbourne Hole Lunar Crater San Carlos Volcanic Field Wyoming Craton Simcoe Shield Volcano Elliot County, KY Diatremes Basin and Range Colorado Plateau Sierra Nevada Superior Province DATABASE CONTENT Sponsored by the National Science Foundation Total Holdings: References: 35 Samples: 657 Num. of Analyses: Whole rock: 10850 Mineral: 16459 Glass: 620 Inclusion: 50 Leachate: 10 Total data points: 27989 Query by: sample location rock type mineral inclusion author major oxide trace element isotopic composition Query by: sample location rock type mineral inclusion author major oxide trace element isotopic composition

2. 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!
