Process of relative dating dating devon farmers
Estimates of the absolute age of prehistoric and geological events and remains amounted to little more than inspired guesswork, as there was no scientific basis for testing such proposals.”With this background, it is strange that the “standard geologic column” that identifies the rock strata on the earth and assigns very old ages to those strata was developed by Sir Charles Lyell in 1830.
This was done 100 years before absolute dating methods were available.
This means that a quartz sandstone deposited 500 million years ago will look very similar to a quartz sandstone deposited 50 years ago.
Making this processes even more difficult is the fact that due to plate tectonics some rock layers have been uplifted into mountains and eroded while others have subsided to form basins and be buried by younger sediments.
One known example where this assumption was used is very misleading.
Climate chronology uses evidence of a climatic change, such as an ice age, as a benchmark for dating.
states, “Before the 20th century, archaeologists and geologists were largely limited to the use of relative dating techniques.
However, forces that can disturb relative dating or at least make it more challenging include multiple geological processes occurring over a short period of time.
If the layers you're examining are very small, it can be hard to determine for sure which occurred first.
