1) isotopic systematics of deformed minerals
变形矿物同位素体系
2) isotopic system
同位素体系
1.
Fast neutron activation method based on the ~(40)Ar/~(39)Ar isotopic system and its application in geosciences;
~(40)Ar/~(39)Ar同位素体系及其在地学上的应用
3) mineral oxygen isotope
矿物氧同位素
4) fission product isotope
裂变产物同位素
5) Sm-Nd isotope systematics
Sm-Nd同位素体系
1.
Both Sm and Nd are similar in ionic radius and in chemical properties, the daughter 143 Nd decayed by the parent 147 Sm through α-process can occupy the same site in mineral lattice as its parent, thus Sm-Nd isotope systematics is easily be closed and can resist later alteration and weathering.
Sm、Nd的离子半径相似、化学性质很相近,母体衰变形成的子体易在矿物晶格中保存下来,故矿物或岩石中的Sm-Nd同位素体系易保持封闭,具有较强的抗风化、抗蚀变能力,是一种有效的定年工具。
6) potassium-calcium isotopic system
钾钙同位素体系
