Data for 40 bedrock samples associated with thermal conductivity dataset

Dates

Start Date
2010
End Date
2013

Summary

40 bedrock samples were collected from surface outcrops in Vermont. Samples are the same set as those analyzed for thermal conductivity as part of the National Geothermal Data System program. All analyses were done at AcmeLabs, Canada. Samples were analyzed using ICP – ES (emission spectroscopy) and ICP-MS (mass spectrometry). 11 major elements plus Ni and Sc were analyzed by ICP-ES following a lithium borate fusion and dilute acid digestion. Analyses include Loss on ignition (LOI) and Leco analysis for total carbon and sulphur. A 45 element suite of trace elements was analyzed using ICP-MS (mass spec). Rare earth elements and refractory elements report from a lithium borate decomposition to give total abundances. Metals were generated [...]
