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 …

Kimberlite magmas are volatile-rich, silica-poor ultrabasic magmas originating as small-
degree mantle melts at depths of 150 km or greater. Alteration and entrained xenoliths …

Plate motion and associated tectonics explain the location of magmatic systems along plate
boundaries [1], however, they cannot give satisfactory explanations of the origin of intra …

Kimberlite volcanism involves the ascent of low viscosity (0.1 to 1 Pa s) and volatile-rich
(CO2 and H2O) ultrabasic magmas from depths of 150 km or greater. Theoretical models …

Extensive descriptions of a wide range of key or world-class mineral deposits of China are
presented in the context of the country's general geology, tectonic units and mineral systems …

Diatremes are carrot-shaped bodies forming the upper parts of very deep magmatic
intrusions of kimberlite rock. These unusual, enigmatic and complex features are famous as …

Neogene to Quaternary volcanic/magmatic activity in the Carpathian-Pannonian Region
(CPR) occurred between 21 and 0.1 Ma with a distinct migration in time from west to east. It …

We review the numerous experimental studies dedicated to unravelling the physics and
dynamics of various parts of a volcanic plumbing system. Section 1 lists the model materials …

The common serpentine–diopside matrix assemblage in volcaniclastic kimberlite (VK) at the
Venetia Mine, South Africa is ascribed to a secondary origin, because of post‐emplacement …

The pre-colonial history (ie before the 16th century) of Tonga and West Polynesia still suffers
from major gaps despite significant scientific advances in recent years, particularly in the …
