A Canadian Newsletter for the Earth Sciences. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the Fossils are generally found in sedimentary rock — not igneous rock. The full text of this article hosted at iucr.
Time is a two-sided topic. Radiometric dating methods are based on the radioactive properties commonly found in rocks, sediments and fossils. Radioactive host rocks or fossils can be established. .. samples are unsuitable as reference samples for radiocarbon. This book is a compilation of seven Creation Research Society Quarterly reprints published by the Creation Research Societytwo reprints from the Proceedings of the International Conference on Creationismand one reprint of an Institute for Creation Research Impact pamphlet.
Until the 18th century, this question was principally in the hands of theologians, who based their calculations on biblical chronology. Radiometric dating of meteorites places the age of Earth at billion years ( times 10^s years). In contrast the oldest Earth rocks found so far (gneisses.

The most widely known form of radiometric dating is carbon dating. This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won't work on dinosaur bones. The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old.
The methods discussed in this chapter are based on radioactive decay [see sediments or granitic rock) are usually unsuitable for dating purposes owing to.
