Beryllium Sedimentation

What are 10Be, 9Be and 7Be? / About Isotopes / Cosmogenic

What are 10Be, 9Be and 7Be? 10 Be and 7 Be are radioactive isotopes of beryllium that are produced in the Earth's atmosphere and surface, (growth rates are determined from the ages), and to estimate sedimentation rates during the past c. 15 Ma. 10 Be has also been used in the study of other processes,

Be Beryllium

Beryllium is a lithophile element and occurs in the Earth's crust at concentrations ranging from 1 to 3 mg kg-1 (Ryan 1999). The small size of the Be2 ion (35 pm) implies that Be behaves incompatibly during early magmatic fractionation.
