Despite very impressive and powerful measurement and characterization tools, physical and chemical analysis methods, the dating of rocks by using radioactive elements depends on very basic assumptions.The significance and relevance of these assumptions have not been demonstrated.

All radiometric dating methods rely upon important assumptions usually not mentioned by evolutionists... rely on these few basic assumptions: - Beginning Conditions Known - Beginning Ratio of Daughter to Parent Isotope Known (zero date problem) - Constant Decay Rate - No Leaching or Addition of Parent or Daughter Isotopes - All Assumptions Valid for Billions of Years - There is also a difficulty in measuring precisely very small amounts of the various isotopes Absolute dates do not necessarily tell us precisely when a particular cultural event happened, but when taken as part of the overall archaeological record they are invaluable in constructing a more specific sequence of events.It is clear that the sedimentary rock was deposited and folded before the dyke was squeezed into place.By looking at other outcrops in the area, our geologist is able to draw a geological map which records how the rocks are related to each other in the field.Radiometric Dating Parent to Daughter Radiometric Dating The 7th grade biology textbook, “Life Science” states on page 138 that scientists, “can accurately determine the age of the rock using radioactive dating methods“.On another page it calls radiometric dates on rocks, “absolute”.

For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.
