K6 pipe is a diamondiferous diatreme in the Buffalo Head Hills kimberlite field of Northern Alberta, Canada. It is thought to have formed about 85 million years ago when this part of Alberta was volcanically active during the Late Cretaceous period.[1] It is typical of melts that originated from the lower mantle.[2]
