diatreme

GLOSSARY OF VOLCANIC TERMS
A funnel-shaped, pipe-like volcanic conduit, usually filled with volcaniclastic debris, emplaced by the explosive energy of gas-charged magmas. Diatremes are believed to result from hydrovolcanic fragmentation and subsequent wall rock collapse (Vespermann and Schminke, 2000, p. 683), and may reach depths up to 2500 meters. Diamond-bearing diatremes are economically important and are referred to as kimberlite pipes.
