2020-5-4It appears none of the gold prospectors spend nor time or money on assaying their black sands for gold value determination. Instead they use a rare earth magnet to tells them what is in there and see that most of the gold is magnetite with sometimes hematite. What little remains goes under the microscope where I see that it is a mix of wolframite scheelite and ircon. Could there be some

The crust and tectonic plates are not the same. Plates are thicker than the crust and consist of the crust plus the shallow mantle just beneath it. This stiff and brittle two-layered combination is called the lithosphere stony layer in scientific Latin. The lithospheric plates lie on a layer of softer more plastic mantle rock called the asthenosphere weak layer
