Process Group The alluvial fan channels are variable gradient streams strongly influenced by colluvial and alluvial sediment deposition AF channels are located on footslope landforms in the t. What is alluvial diamond mining Alluvial diamond mining is the term used to describe the process through which diamonds are recovered from such deposits of sand gravel and clay Large concentrations of alluvial diamond deposits are mined on an indust 685 Kenneth L.

Tracing The Path of Conflict Diamonds. Just Another Form of Carbon. 75-120 miles below the earth’s surface, extreme heat and pressure can cause carbon atoms to crystallize, forming diamonds.. Diamonds are then carried to the earth’s surface during volcanic eruptions, where they must cool quickly or turn into graphite or carbon dioxide. . 5 THEMES OF GEOGRAPHY. LOCATION. -.
