以系统的岩石学及沉积相分析为基础,深入探讨了隆额尼—昂达尔错古油藏白云岩及其伴生灰岩的铅同位素特征,认为该区白云岩及伴生灰岩具有统一的铅来源,铅主要来自中央隆起带变质岩、岩浆岩及再旋回沉积的三叠系地层,为地幔、造山带、地壳等多源混合的异常铅。
补充资料:氢同位素动力学同位素效应
分子式:
CAS号:
性质:在化学反应过程中反应物本身因同位素取代而改变能态,引起化学反应速度的差异。氢同位素动力学同位素效应很大,α=kH/kD可达2~10左右。0℃时Al4C3与水反应α=3.9,30℃时Fe与H2SO4反应α=6.6。轻水电解时比重水分解速度快,动力学同位素效应随电极材料、电解条件而变,氢-氘的α在3~12之间。当前采用减容电解来制取终浓重水。
