The JD-03 pipe is a kimberlite diatreme in Nunavut, Canada, located from the Jericho Diamond Mine, where diamonds were mined from the late 1990s. It was discovered in 1996 and is interpreted to be pyroclastic with intense serpentinization.
The JD-03 pipe formed by an explosive eruption when this part of Nunavut was volcanically active. In addition, it contains several crustal xenoliths including limestone and granite.
