Radiometric dating lab
How radiometric dating works in general Why methods in general are inaccurate Why K-Ar dating is inaccurate The branching ratio problem How Errors Can Account for the Observed Dates Why older dates would be found lower in the geologic column especially for K-Ar dating Do different methods agree with each other on the geologic column?
Possible other sources of correlation Anomalies of radiometric dating Why a low anomaly percentage is meaningless The biostrategraphic limits issue Preponderance of K-Ar dating Excuses for anomalies Need for a double-blind test Possible changes in the decay rate Isochrons Atlantic sea floor dating Dating Meteorites Conclusion Gentry's radiohaloes in coalified wood Carbon 14 dating Tree ring chronologies Coral dating Varves Growth of coral reefs Evidence for catastrophe in the geologic column Rates of erosion Reliability of creationist sources Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium.
They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.
Beta Analytic only provides Radiometric PLUS for charcoal, dung, peat, plants and seeds, shells, corals, and wood. AMS Dating – The AMS radiocarbon dating technique is suited for samples containing 0.00025 grams to 0.3 grams of final carbon.
Radiometric PLUS – Standard service is for samples containing at least 3.0 grams to 4.0 grams of final carbon (remaining carbon after all necessary pretreatments and chemical syntheses have been performed). Quoted precision generally ranges from 0.5% to 3% of the sample age and is independent of sample size.
Water, adhering mineral matter, and carbon loss from essential chemical pretreatment are basic factors to consider when determining the amount of material required.
For example, only 25% of the weight of a submitted, clean charcoal sample is available for analysis (1 gram final carbon from 4 grams submitted charcoal).
