Semiquantitative mineralogy results from powder X-ray diffraction (XRD) analyses of mineral scales from The Geysers geothermal field, California, USA

This data release provides semiquantitative mineralogy results from X-ray diffraction (XRD) analyses of mineral scales from The Geysers vapor-dominated geothermal field in California. The mineral species and their abundances are reported in weight percent and values have been normalized to total 100 percent for each sample. The X-ray diffraction results show that the mineral samples from the wellh

Method development for determination of trace amounts of silicon in hydrofluoric acid digests of biological samples and lung biopsy tissues by ICP-MS

A method was described for determination of trace levels of silicon by inductively coupled plasma mass spectrometry (ICP-MS) from hydrofluoric (HF) digests of biological samples. The volatility of silicon in HF digests was examined with synthetic solutions as well as soil and mine waste samples. A digestion scheme was optimized to achieve complete dissolution, avoid loss of volatile silicon specie
