Clinopyroxene-melt equilibrium temperature and pressure of Cenozoic basalts with special reference to the genesis of mantle xenoliths in some areas of eastern China;

The Quaternary basalts in Shandong Province contain mantle xenoliths of varied quantities and sizes.

The mantle xenoliths collected from these three localities have been described in this paner.

In eastern China there are more than one hundred reported localities of mantle xenoliths, on which a lot of studies have been carried out.

The upper mantle geotherm and rheology for Mingxi, Fujian Province, has been constructed through a detailed study of mantle xenoliths collected from this area.

Major, trace element composition and Sr-Nd-Pb isotopes of the Cenozoic basalts from Yangyuan (Hebei Province) and Datong (Shanxi Province), which are located to west of the Daxinanling-Taihanshan gravity lineament, as well as mineral chemistry, major and trace element composition and Sr-Nd isotopes of mantle xenoliths from Yangyuan are reported in this thesis.

This paper deals with deformation textures, petrofabrics and dislocation micros-tructures of olivine from the mantle-derived xenoliths in the Penghu Islands, Taiwan.

Laser-fluorination technique has been used to determine the O-isotopic ratios of mineral separates from mantle-derived xenoliths from the Yitong.
