Problems dating metamorphic rocks

The radiometric decay series commonly used in radiometric dating of rocks are detailed in the following sections.

The choice of method of determination of the age of the rock is governed by its age and the abundance of the appropriate elements in minerals.

Detectors at the end of the tube record the number of charged particles of a particular atomic mass and provide a ratio of the isotopes present in a sample.

This is the most widely used system for radiometric dating of sedimentary strata, because it can be used to date the potassium-rich authigenic mineral glauconite and volcanic rocks (lavas and tuffs) that contain potassium in minerals such as some feldspars and micas.

Scientists believe they can indirectly date sedimentary rocks using radiometric dating if they find igneous or metamorphic rock imbedded in or around a sedimentary rock layer.

This of course presupposes that radiometric dating works consistently as a dating technique in the first place. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him.

Dating the particles which make up the rock wouldn’t give you the age of the rock itself.

In addition, the redeposition process upsets the conditions necessary to achieve accurate results through radiometric dating.

This dating method is principally used for determining the age of formation of igneous rocks, including volcanic units that occur within sedimentary strata.It is also possible to use it on authigenic minerals, such as glauconite, in some sedimentary rocks.Radiometric dating of minerals in metamorphic rocks usually indicates the age of the metamorphism.A number of elements have isotopes (forms of the element that have different atomic masses) that are unstable and change by radioactive decay to the isotope of a different element.Each radioactive decay series takes a characteristic length of time known as the radioactive half-life, which is the time taken for half of the original (parent) isotope to decay to the new (daughter) isotope.

QUESTION: Can we date sedimentary rocks using radiometric dating techniques?
