Dating sedimentary rocks using in situ U-Pb geochronology of. The probability of a parent atom decaying in a fixed period of time is always the same for all atoms of that type regardless of temperature, pressure, or chemical conditions. The time required for one-half of any orinal number of parent atoms to decay is the half-life, which is related to the decay constant by a simple mathematical formula. Zircon crystals ≥10 μm were identified by optical microscopy of 12 polished thin sections of 8 samples.
