Tilting and erosion of the older rocks took place during this time, and if there was any deposition going on in this area, catchy headline the evidence of it is now gone.

The simplest and most intuitive way of dating geological features is to look at the relationships between them. The most widely used and accepted form of absolute dating is radioactive decay dating. The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating. The same inductive mechanism is applied in archaeology, geology and paleontology, by many ways.
