This paper presents an overview of recent studies dealing with different ages of mantle peridotitic xenoliths and xenocrysts from the North China Craton, with aim to provide new ideas for further study on the destruct...
The oriented lamellar K-rich exsolutions within clinopyroxene host were recognized in garnet peridotite mas-sif at Zhimafang in the Sulu ultrahigh pressure metamorphic terrane, eastern China. EMP and TEM analyses reve...

Hydrogen isotopic compositions of four am-phibole grains from three pieces of Iherzolite xenoliths in Cenozoic basanites of Nushan, eastern China have been analyzed by ion microprobe. σD values of all analyzed points...
Leaching experiment has been carried out on mantle xenoliths with different petrographic features in order to directly characterize the nature of intergranular components. ICP-MS analyses of leachates show that they a...
Studies were carried out on the early phase of fluid inclusions which occur in residual olivines in harzburgite from the Yushigou ophiolitic mantle peridotite, the North Qilian Mountains. Components of these inclusion...
Oxygen isotope analyses were carried out by the laserprobe technique for mineral separates from mantle xenolith and megacryst in Cenozoic basalts, East China. The results not only give the δ I8O range consistent with...
The osmium isotopic ratio of 187Os/ 188Os ranging from 0.126 to 0.127 for the primitive upper mantle (PUM) is obtained according to the correlation between 187Os/ 188Os and Al 2O 3 of mantle-derived xenoliths and orog...
The metamophic peridotite of ophiolite belt in Mt. Ailao is composed of lherzolite and harzburgite. The former shows the charateristics of primary pyrolite and the latter shows those of deleted (relict)pyrolite. By pa...
Spinel peridotite xenoliths from Wangqing, NE China exhibit correlative variations in texture, temperature, geochemistry and radiogenic isotopes. This suggests that the Wangqing xenoliths may come from a mantle diapir...
