Analytical Fees
Primary Services
- Mineral separations (99% pure) are $200 U.S. a sample
Includes: muscovite, biotite, hornblende, plagioclase, potassium feldspar, glass and XRF of feldspar separate for K/Ca ratio.
Of note, sample separation cost is included in heating experiment costs and no discount for pure separated mineral aliquots (but appreciated).
- Laser incremental 40Ar/39Ar heating experiments (~8 to ~10 steps) are $600 U.S. per sample
Includes: Single mineral phase heating experiments (multiple runs if needed), sample
preparation, irradiation costs, data reduction, digital report, and publication quality figures on request.
- Laser total fusion 40Ar/39Ar experiments are $600 U.S. per sample for ~10 grains.
Includes: ~10 single grain fusions, sample preparation, irradiation costs, data reduction, digital report, and publication quality figures on request. In addition we will provide a statistically analysis of peak populations of the produced data.
- Laser total fusion 40Ar/39Ar experiments are $2000 U.S. per sample for ~100 grains. We can also discuss a per grain cost.
Includes: ~100 single grain fusions, sample preparation, irradiation costs, data reduction, digital report, and publication quality figures on request. In addition we will provide a statistically analysis of peak populations of the produced data.
- Temperature recorded furnace incremental 40Ar/39Ar heating experiments (~20 to ~30 steps) are $1500 U.S. per sample
Includes: Single mineral phase heating experiments (multiple runs), sample
preparation, irradiation costs, data reduction, digital report, and publication quality figures on request. We also include a single Laser incremental 40Ar/39Ar heating experiment (~8 to ~10 steps) on potassium feldspar samples to “predetermine if the sample is a good candidate for furnace isothermal-step heating experiments. We prefer
collaborations on potassium feldspar samples because of the amount of work involved. We will derive thermal history models (Time-temperature) from the analysis.
