Zircon crystals are valuable in dating rocks for several reasons:
1. Uranium-Lead Dating: Zircon crystals often contain small amounts of uranium and thorium. Over time, these elements decay into lead. Because zircon crystals tend to reject lead upon formation, any lead present in zircon is usually the result of uranium and thorium decay. This allows for highly accurate dating of the rock.
2. Preservation: Zircon is relatively hard and can resist weathering, erosion, and even metamorphism. Thus, it can often be found in samples that have been subjected to severe geological processes. This makes zircon a useful tool for dating very old rocks.
3. Precision: Zircon dating can be incredibly precise, able to determine the age of rocks within a very small margin of error. This is largely due to the slow decay rates of uranium and thorium and the accuracy of modern mass spectrometry methods.
4. Trace of Original Magma: Zircon can trap and hold onto some of the original magma or lava from which it crystallized. This "trapped" portion can provide important clues about the conditions under which the rock formed.
5. Zircons Are Ubiquitous: They occur in a wide variety of rock types (like igneous, metamorphic, and sedimentary), making them highly useful for geologists studying a diverse range of geological formations.
