How do geologists use radiometric dating to date sedimentary rocks? Are you sure you want to delete this answer? Can we date sedimentary rocks using radiometric dating techniques? Sedimentary rocks cannot be dated directly using radiometric dating, which is based on the idea that when rocks are in liquid form, their radiometric clock resets. This technique is generally used to date igneous and metamorphic rock, which are rocks that were once melted due to extreme heat and pressure.
Radiometric dating determines how long ago the liquid rock solidified into solid rock. Sedimentary rock on the other hand consists of sedimentary particles which were removed and deposited somewhere else by some sort of fluid generally wind and water.
The sedimentary particles predate the rock which they form. In addition, the redeposition process upsets the conditions necessary to achieve accurate results through radiometric dating.
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 How do geologists use radiometric hookup to date sedimentary rock layers indirectly in the first place.
In relative courting, sequences of rocks were dated as being older than others by making use of distinctive feature of their stratigraphic relationships undisturbed sedimentary rocks are laid down so as that the decrease ones are the older ones, and when it comes to igneous rocks, the igneous rocks that lie upon or are intruded into different rocks are the more youthful ones.
And, at the same time as there are quite a few diverse fossils in a rock their man or woman ranges yield a constrained age span for that rock. A radioactive rock that would nicely be dated would lie upon a mattress that has no such radioactivity, yet is loaded with fossils.
A mattress below that one would no longer have fossils nor radioactivity, yet when there's a mattress below that which will be easily dated then the intervening one has to have an intermediate age.
