Decay of Kimberlite Pipes
More Depth on Kimberlites

Kimberlite pipes look like carrots in the ground and a lamporite looks like a champaign glass. The difference is only in the fact that the kimberlite did not spread out when it hit the surface.

Both are weathered down to sand and crushed and ground down by glaciation in West Quebec. There can be hundreds of feet of overburden.

So how do we find them? The first step can be locating possible kimberlitic pipes through geomagnetic maps. However, it is more practical to run the geomagnetic survey after finding indicator minerals. We know a kimberlite pipe is nearby when we find associated indicator minerals like pyrope garnets (high crome, low calcium, deep red to purple), ilmenite (silvery balck with bluish tint). Other minerals include Chrome Diopside, Chrome Spinel, and Olivine.
