This paper reviews key characteristics of kimberlites on the Ekati property, NWT, Canada. To
date 150 kimberlites have been discovered on the property, five of which are mined for …

Mantle metasomatism is a relatively recent concept introduced in the early 1970s when
detailed studies of lithospheric mantle rock fragments (xenoliths), brought to the surface of in …

Cratons are Earth's ancient continental land masses that remain stable for billions of years.
The mantle roots of cratons are renowned as being long-lived, stable features of Earth's …

The analysis of micro-inclusions in fibrous diamonds from the Diavik mine, Canada revealed
the presence of high density fluids (HDFs) that span a continuous compositional range …

Diamonds form in the upper mantle during episodic events and have been transported to the
Earth's surface from at least the Archean to the Phanerozoic. Small diamonds occur as …

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 …

Based on a compilation of more than 100 kimberlite age determinations, four broad
kimberlite emplacement patterns can be recognized in North America:(1) a northeast …

Microinclusions analyzed in a coated diamond from the Diavik mine in Canada comprise
peridotitic minerals and fluids. The fluids span a wide compositional range between a …

Mineral deposits exhibit heterogeneous distributions, with each major deposit type showing
distinctive, commonly unique, temporal patterns. These reflect a complex interplay between …

New Rb–Sr age determinations using macrocrystal phlogopite are presented for 27
