Which mechanism leads to helium accumulation within zircons?

💡 Explanation

Alpha decay of uranium and thorium within zircon crystals releases alpha particles, which capture electrons to form helium. Because the process is Alpha decay, therefore helium concentrates over geologic timescales, rather than from other forms of radioactive decay.
