Short summary
We report a new method of obtaining representative samples of drill core with an example from the lower oceanic crust in the Hess Deep rift. Sawing drill core in half produces 1.3 g of rock per centimeter of core cut – material usually discarded. We show that when collected and analyzed properly, these samples reveal both the chemical composition of lower oceanic crust and the reactions that change the mineralogical and chemical composition of that crust.
