Harvey Lake Itrax QSpec calibration
Description
Complete dataset for Harvey Lake sediment samples analyzed using Itrax X-ray fluorescence core scanning (XRF-CS) converted to absolute concentrations using Qspec software. Data was compared to Green River Shale standard to derive calibration equations (USGS standard SGR-1). Sediment samples were recovered Harvey Lake, NB, Canada in summer 2016 using an Ekman grab sampler. Twenty cubic cm of sediment was subsampled, centrifuged and dried, loaded into custom-design sample reservoirs, and analyzed using an Itrax XRF-CS device at 0.2 mm resolution for 15 seconds per interval at 30 kV and 19 mA. See Gregory et al., (submitted) for more thorough description of methodology. Elemental concentrations are presented in ppm MSE = Mean square Error Surface Sample and position are present in mm Mo Inc = Incoherent X-ray Scatter Mo Coh = Coherent X-ray Scatter
