Abnormal lithium isotope composition from the ancient lithospheric mantle beneath the North China Craton

Lithium elemental and isotopic compositions of olivines in peridotite xenoliths from Hebi in the North China Craton provide direct evidence for the highly variable δ(7)Li in Archean lithospheric mantle. The δ(7)Li in the cores of olivines from the Hebi high-Mg# peridotites (Fo > 91) show extreme variation from -27 to +21, in marked deviation from the δ(7)Li range of fresh MORB (+1.6 to +5.6) al...

Creation and Destruction of Lithospheric Mantle beneath the North China Craton

Title of Dissertation: CREATION AND DESTRUCTION OF LITHOSPHERIC MANTLE BENEATH THE NORTH CHINA CRATON Jingao Liu, Ph.D., 2011 Dissertation directed by: Professor Roberta L. Rudnick, Geology Professor Richard J. Walker, Geology Mantle peridotites carried in volcanic rocks provide a window into the composition, age and origin of deep lithospheric mantle. Previous studies of mantle peridotites hav...

Lithospheric structure of the Pilbara Craton, Capricorn Orogen and northern Yilgarn Craton, Western Australia, from teleseismic receiver functions

The upper lithospheric structure from the Pilbara Craton, across the Capricorn Orogen, to the northern Yilgarn Craton is determined from high-fidelity broadband seismic data. Three-component temporary stations were deployed in a line running southwards from Marble Bar, Western Australia, at approximately 118 E longitude. They were in position between July and October 2000. Receiver functions ar...

Late-Archean to Early Proterozoic lithospheric mantle beneath the western North China craton: Sr-Nd-Os isotopes of peridotite xenoliths from Yangyuan and Fansi

Receiver Function Imaging of Mantle Transition Zone Discontinuities Beneath the Tanzania Craton and Adjacent Segments of the East African Rift System

The mantle transition zone (MTZ) discontinuities beneath the Tanzania Craton and the Eastern and Western Branches of the East African Rift System are imaged by stacking over 7,100 receiver functions. The mean thickness of the MTZ beneath the Western Branch and Tanzania Craton is about 252 km, which is comparable to the global average and is inconsistent with the existence of present-day thermal...
