根据对变生锆石在温度为300～600℃的不同化学成分溶液互相作用的研究表明,放射性成因铅的丢失发生在两种反应速度常数时,此时变生锆石中约有90％的铅原子以具不超过16.74kJ·mol~(-1)的活化能转入溶液中。由于温度升高到600℃锆石晶体结构的复原,铅丢失的活化能值增加到71±8kJ·mol~(-1)。在变生锆石同溶液作用的最初的几个小时里有铀的丢失,经过比较长的时间作用,铀的丢失被铀含量在反应产物中增加所取代,这可从被新形成的新相捕获铀而得到解释,例如碱性介质中的斜锆石。
According to the study on the interaction of different zircons with different chemical compositions at temperatures ranging from 300 to 600 ℃, the loss of radiogenic lead occurs at two reaction rate constants. At this time, about 90% of the Lead atoms with an activation energy of no more than 16.74kJ · mol ~ (-1) into the solution. The activation energy of lead loss increased to 71 ± 8kJ · mol ~ (-1) due to the recovery of the crystal structure of zircon at 600 ℃. Uranium loss occurs during the first few hours of the reaction of the altered zircon with the solution. Over time, uranium loss is replaced by an increase in uranium content in the reaction product, Capture of uranium is explained, for example, in the alkaline media,
