(2001)The petrology and geochemistry of shallow continental lithospheric mantle (SCLM) can be studied via (1) tectonically emplaced ultramafic massifs and (2) mantle xenoliths entrained in alkaline magmas. Data from these two ...
-
(2002)Micro-Raman spectroscopic analysis allows us to estimate the internal pressure of small fluid inclusions. We applied this method to CO2-dominated fluid inclusions in mantle-derived xenoliths. The pressures estimated from ...
-
(2005)Garnet-facies continental mantle is poorly understood because the vast majority of mantle xenoliths in continental basalts are spinel peridotite. Peridotite xenoliths from Vitim (southern Siberia) and Mongolia provide some ...
-
(2004)Information on the structure of the upper mantle comes from two main sources. Regional seismic studies provide indirect information on large portions of the lithosphere, and mantle xenoliths provide direct information about ...
-
(2003)Diffuse Cenozoic volcanism in Mongolia forms part of a widespread tectono-magmatic province that extends from NE China to Lake Baikal, Siberia. Mafic lavas from the Gobi Altai, southern Mongolia (33 Ma) and Hangai, central ...
-
(2002)Lower crustal garnet granulite xenoliths from beneath the Kola-Karelian domain of the Fennoscandian Shield (Russia) were brought to the surface in Devonian lamprophyre diatremes. To establish the relationships between ...
-
(2002)Sulfide phases in peridotitic mantle xenoliths from Ichinomegata in Japan, Nunivak Island in Alaska, and southern Africa occur as globular grains within silicate minerals, and along grain boundaries of silicate and oxide ...
