We'll explore both relative and numerical dating on our quest to understand the process of geological dating.Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.
Scientists are always spouting information about the ages of rocks and fossils. Well, they figure it out using two different methods: relative dating and numerical dating.
Let's find out more about these geological dating methods in order to understand how Paul the Paleontologist can be so sure about the age of his dinosaur fossils.
U–Pb and U-series analyses of four U-rich opal samples using sensitive high-resolution ion microprobe (SHRIMP) demonstrate the potential of this technique for the dating of opals with ages ranging from several tens of thousand years to millions of years.
These volcanic rocks in the Sangxiu Formation, for which age is close to that of Bunbury basalt in southwestern margin of Australia, and older than that of Rajmahal basalt in northeastern India, maybe considered as the products of early activity of the hotspot represented by the Rajmahal basalt.
