Methods of Dating the Age of MeteoritesRadiometric Dating This Old Earth

Methods of Dating the Age of Meteorit Meteorites are among the oldest objects we know about formed about 45 billion years ago But how do scientists know this This article describes the principles and methods used to make that determination There are well known methods of finding the ages of some natural objectsIf the material being tested was not a closed system and parent or daughter isotopes were able to migrate through the material radiometric dating would yield an inaccurate age It is for this reason that geologist must take care to ensure that a material was unaltered before radiometrically dating

Chapter 8 Radiometric Ages How accurate are Carbon 14 and other radioactive dating

Chapter 9 Radiometric Time Radioactive Decay 1 Figure 914 Geologists determine the ages of rocks using the principles of radioactivityCertain elements like uranium radium and other elements are unstable and have the tendency to spontaneously disintegrate forming an atom of a different element and emitting radiation in the processOther radiometric dating methods There are various other radiometric dating methods used today to give ages of millions or billions of years for rocks These techniques unlike carbon dating mostly use the relative concentrations of parent and daughter products in radioactive decay chains

To be a bit pedantic but also to draw an important distinction between the use of radiometric dating for geochronology vs thermochronology for Potassium Argon or the more widely used Argon Argon variant these days and many other radiometric system the mineral starts accumulating daughter product ie the clock starts when the mineral Carbon 14 Radiometric Dating and Index Fossils Carbon dating is used to determine the age of biological artifacts up to 50 000 years old This technique is widely used on recent artifacts but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old

How Old is the Earth Radiometric DatingWhat is the difference between carbon dating and

Radiometric dating is based on the decay of long lived radioactive isotopes that occur naturally in rocks and minerals These parent isotopes decay to stable daughter isotopes at rates that can be measured experimentally and are effectively constant over time regardless of physical or chemical conditionsAug 13 32 Carbon dating is radiometric dating using the carbon 14 isotope Carbon 14 is used for fossils of fairly recent origin as it becomes less and less accurate beyond 10 half lives about 50

Zircon can also survive metamorphism Chemically zircon usually contains high amounts of U and low amounts of Pb so that large amounts of radiogenic Pb are produced Other minerals that also show these properties but are less commonly used in radiometric dating Radiometric dating uses the decay of isotopes of elements present in minerals as a measure of the age of the rock to do this the rate of decay must be known the proportion of different isotopes present when the mineral formed has to be assumed and the proportions of different isotopes present today must be measured

Unreliability of Radiometric Dating and Old Age of the EarthDebunking Creationism Radiometric Dating Is Unreliable

If one does not know the geologic period of a rock by other means then of course one is likely to date it to find out and then of course the date agrees with the geologic period and this will not be seen as anomalous So it is difficult to know what would be a reasonable test for whether radiometric dating is reliable or notRadiometric dating methods are very accurate and very trustworthy Creationist arguments to the contrary are riddled with flaws as is the scientific research used by them to support their position
