Because Indiana has significant resources of coal, coal waste, and coal combustion products that are potential resources of critical minerals, this project developed a data preservation strategy for these coal related materials. Rare Earth Elements (REE) are the principal groups of critical minerals considered in this data preservation project, and our strategy for data preservation is to develop databases for individual groups of coal and coal-related materials. When completed, these databases will be combined under an inteactive application that will allow users to quickly locate selected sites and learn which data are available.

Inductively coupled plasma - optical emission spectrometry (ICP-OES) analysis data compiled using sample preparation procedures outlined by ASTM D2013/D2013M-18 and ASTM D6357, and using two independent sets of element standards for instrument calibration. Additional analysis methodologies are described in detail in the resulting publication Rare earth elements and yttrium in Pennsylvanian coals and shales in the eastern part of the Illinois Basin (Mastalerz et al., 2020).

Geoscientific collections managed by Indiana Geological & Water Survey are aggregated in the National Digital Catalog to enhance discovery and use of valuable samples and data for further scientific research. Contact information and material access instructions are provided for the individual collections.
The Indiana Geological and Water Survey received support from the National Geological and Geophysical Data Preservation Program to inventory, reduce, and rehouse 794.7 linear feet of petroleum and water well borehole records into archival-quality boxes, create a dedicated and functional Records Center at its renovated home on IU’s Bloomington campus by installing a high-density mobile shelving unit, and cull resources from 26,000 files housed on its internal server to incorporate usable records into the public-facing IGWS Digital Collections website. These tasks represent ongoing efforts to centralize, consolidate, and enhance public and research access to the physical records displaced during renovation and digital...
The Indiana Geological and Water Survey Reference Library is a more than 2,000 volume non-lending resource open to the public during normal business hours. The library contains copies of IGWS publications as well as external publications covering broader geological topics that apply to the Indiana region.
