查询词典 isotopic

Re is moderately incompatible element, while Os is highly compatible. As they are highly siderophile, ReOs isotopic system can provide unique insight in dating and tracing research compared to other longlived radiogenic isotope systems (e.g. RbSr, SmNd, UThPb ) which involve lithophile elements partitioning into silicate rather than metal or sulfide.

Re为中等不相容元素，Os则属强相容元素，与母子体均为不相容元素的RbSr、SmNd、UThPb等同位素体系相比，具亲铁、亲硫性的ReOs同位素体系在定年和示踪研究中显示出特殊性，受到了地学家高度重视，其应用正走向普及。

During such a long period,it seems impossible that no isotopic exchange between mantle materials and original surface rock would occur at a depth of ≥100km where the temperature would rise to ≥700℃.
