Back in my geology school days in the mid to late 70's, my understanding was that basaltic rocks were unsuitable for radiometric dating. This is because concentrations of elements such as Uranium (U), Rubidium (Rb), and Potassium (K) are too low in such mafic rocks.
But I now see members referring to radiometric datings of oceanic crust rocks that I must presume to be basaltic. I have done searches to try to determine how these datings are done, but have never been able to find anything.
So, the question is, how are these basaltic rock datings done?
