Summary(Plain Language Summary, not published)
Measuring the age of rocks is key to understanding a range of geological processes. The process of radioactive decay is fundamental to determining accurate ages. Improved analytical techniques now allow the analysis of very small samples for which assumptions about retention of radiogenic daughter decay products may not be valid. This paper uses the unique capabilities of the SHRIMP ion microprobe to assess loss of radiogenic daughter products from the surface of crystals. The results indicate that daughter product loss may be significant and should be corrected for in order to determine accurate ages.
