Highlights

?A new method for Re–Os isotope dating organic-rich sedimentary (ORS) rocks by using an H2O2–HNO3 solution as the digestion medium.

?The optimum method is a H2O2:HNO3 ratio of 5 to complete spike–sample equilibration and to minimize the amount of detrital Re and Os in the system.

?The H2O2–HNO3 method may increase the precision and accuracy of Re–Os depositional ages of organic-rich sedimentary systems.

?This new method is environment-friendly in comparison to the conventional CrO3–H2SO4 digestion method.

？通过使用H 2 O 2-HNO3溶液作为消化培养基，通过使用H 2 O 2-HNO3溶液进行富含有机脂肪沉积（ORS）岩石的新方法。

？ Optim UM方法是一个H2O2：HNO3比率为5，以完成穗样品平衡，并最大限度地减少系统中的脱果RE和OS的量。

？ H2O2-HNO3方法可能会增加重新操作系统沉积年龄的精度和准确性有机沉积系统。

？与传统的CRO3-H2SO4消化方法相比，这种新方法是环保的。
