Maar-diatreme volcanoes are produced by explosive eruptions that cut deeply into the
country rock. A maar is the crater cut into the ground and surrounded by an ejecta ring, while …

Diamond is not a common rock-forming mineral (an exception being “diamondite”; see
Jacob and Mikhail 2022, this volume) nor a common crustal mineral (the exceptions being …

North American kimberlite magmatism spans a period of time in excess of 1 billion years
from Mesoproterozoic kimberlites in the Lake Superior and James Bay Lowlands region of …

Kimberlites are volatile rich magmas that ascend from deep in the mantle at high velocities,
then as they reach a 'root zone'at 1–3 km in depth they either discharge explosively through …

Although kimberlite pipes/bodies are usually the remains of volcanic vents, in-vent deposits,
and subvolcanic intrusions, the terminology used for kimberlite rocks has largely developed …

Thirty new high‐precision U‐Pb perovskite and zircon ages from kimberlites in central North
America delineate a corridor of mid‐Cretaceous (115–92 Ma) magmatism that extends∼ …

In Canada more than 770 kimberlites have erupted in diverse tectonic settings over a period
of 1000 Ma and over an area at least 5000 km across. The kimberlites represent at least 30 …

Abstract The Igwisi Hills volcanoes (IHV), Tanzania, are unique and important in preserving
extra-crater lavas and pyroclastic edifices. They provide critical insights into the eruptive …

Five significant problems hinder advances in understanding of the volcanology of
kimberlites:(1) kimberlite geology is very model driven;(2) a highly genetic terminology …

Abstract The recently recognised Sask Craton, a small terrane with Archean (3.3–2.5 Ga)
crustal ages, is enclosed in the Paleoproterozoic (1.9–1.8 Ga) Trans Hudson Orogen (THO) …
