摘要: Abstract Preliminary U-series data are presented on the disequilibria of mineral separates surface samples from Eye-Dashwa lakes granite (Canada). Most analyses ferromagnesian, quartz-plus-feldspar, and zircon-plus-sphene grains, show that leaching U has taken place such 234 U/ 239 U≤ 1 230 Th/ 1. The simple leach model in a companion paper was used to explain these characteristic ratios. It is suggested may be zircon sphere grains estimate U-leach rates, this relevant suggestion using sphene-like hosts as primary barrier safe disposal nuclear waste. A full analysis mobility within given rock volume not possible due our limited base inability monitor labile directly.
