From which geological feature do most diamond mines today come?

• A. Kimberlite intrusions
• B. Submerged reef structures
• C. Pipes
• D. Shallow alluvial sands

Answer: (C)

Diamonds are brought to the surface by kimberlite magma that forms vertical conduits called pipes. These pipes crystallize diamonds into concentrated, mineable ore bodies, making them the primary source for most diamond mines today. While alluvial sands and reef-like structures exist, they are secondary deposits and don’t account for the bulk of large, current mining operations. Kimberlite intrusions describe the rock type that creates the pipes, but the actual mineable deposits are the pipe-like bodies, which is why pipes is the best answer.
