The first step after a field trip is to pick a rocks of interest and crash or cut them, make a thin sections and powders. After you register rocks into the rock depository referred as DREAM, it is time to create both powders and thin sections. This lab is dedicated to crash rocks and deal minerals. One of two rooms is dedicated only for crushing. You roughly crash a rock by Jaw crusher and turn into powder by Disk mill or Rod mill. On the other room, to draw isochron, mineral separation would be conducted. There are two ways to do so by magnetic separation by Frantz Isodynamic Separator and density separations using heavy liquid. Or you separate minerals using a combination of microscope, tweezers, hands, and eyeballs.
