Reading: Abundance of Elements in Earth''s Crust | Geology

Reading: Abundance of Elements in Earth''s Crust. The table shows the abundance of elements in Earth''s crust. Numbers show percentage or parts per million (ppm) in mass; 10,000 ppm = 1%. Note that numbers are estimates, and they will vary depending on source and method of estimation. Order of magnitude of data can roughly be relied upon.

Feature. Text Size. 06.14.03. Prospecting from Orbit. Mining for ore isn''t what it used to be. A hundred years ago when a mining operation happened upon a copper vein or a gold deposit, the outfit would often just rip out the local flora, excavate the land, and dump the resulting waste and rubble in the nearest pristine stream or flowering meadow.
