In this collection of lab-based activities, students will learn about the concepts of radiation and half-life in order to gain an understanding of the use of radiocarbon dating as a method of absolute ...

For decades, scientists have relied on tree rings to estimate how long trees can live. But new research suggests that this widely used method may have been underestimating the lifespan of many ...

When paleontologists dig up a fossil from the ground, how do they figure out the age of the piece of history? It’s not as simple as you may think. You may have heard of the widely-used carbon dating ...

Radiocarbon dating has become indispensable for reconstructing prehistoric population trends by providing chronological markers for organic materials. Archaeological demography employs techniques such ...

Radiocarbon dating remains the cornerstone of chronological frameworks in archaeology, exploiting the decay of carbon-14 in organic remains to establish absolute ages. Since its inception in the ...

Geologic assessment of active tectonism depends on two key measures: the age and the amount of deformation of a given stratigraphic unit. The amount of deformation can normally be measured with ...
