: This point often corresponds to the age of a later metamorphic event or disturbance that caused the lead loss. Interpretation Guidelines
: For accurate results, "common lead" (lead not produced by radioactive decay inside the mineral) must be correctly subtracted. High-precision tools like SHRIMP (Sensitive High-Resolution Ion Microprobe) are often used to refine these 3D planar regressions . Discordia atomica
A "proper guide" to interpreting a Discordia line involves understanding its two key intersections with the (the mathematically determined line where the age equals the Key Intercepts : This point often corresponds to the age
: This point typically represents the original age of crystallization for the minerals. It indicates when the isotopic clock first started ticking. A "proper guide" to interpreting a Discordia line
: Scientists use mathematical approaches like the "York" or "Ludwig" methods to perform a linear regression of measurements to define the Discordia line.
