Nominally anhydrous minerals in 46 peridotite xenoliths hosted by Cenozoic basalts from five localities (Fangshan, Penglai, Qixia, Changle, and Hebi) of the eastern part of the North China Craton (NCC) have been investigated by Fourier transform infrared spectrometry (FTIR). The water contents (H2O wt %) of clinopyroxene (cpx), orthopyroxene (opx),...
Article
Major and trace element and the H2O contents of minerals in peridotite xenoliths hosted by the Cenozoic basalts of Jiande in the Cathaysia block were evaluated using electron microprobe, laser-ablation ICP-MS and Fourier transform infrared spectroscopy, respectively. The correlations among the major elements of the minerals define a melting trend,...
Article
Recognizing juvenile and relict lithospheric mantle is crucial in unraveling the mechanism of lithospheric thinning (delamination vs. thermal/mechanic erosion). The H2O contents and Sr–Nd isotopic compositions of juvenile lithospheric mantle are expected to be similar to the MORB source (asthenospheric mantle), whereas those of the relict lithosphe...
Article
This study reports Ca-Fe isotope compositions of mineral separates in a set of peridotite xenoliths including ten lherzolites, one harzburgite, and one wehrlite from Hainan Island, south China. Iron isotope compositions show a small variation (<0.15‰ of δ56/54Fe) among olivine (ol), orthopyroxene (opx), and clinopyroxene (cpx). Δ44/40Caopx-cpx (δ44...
Article
It has been suggested that the longevity of cratons is related in part to the low water content of their deep mantle roots, which leads to a much higher viscosity than that of the underlying asthenosphere. Consequently, removal of cratonic roots is thought to be closely related to hydration of the lowermost lithospheric mantle. The North China Crat...

Anhydrous, medium/coarse-grained spinel bearing mantle xenoliths from the Subei Basin, Eastern China have mineral arrangements that reflect low energy geometry. Because of clinopyroxene modal contents, they are grouped into cpx-rich lherzolites (cpx ≥ 14percentage), lherzolites (8 < cpx < 14%), cpx-poor lherzolites (6 < cpx ≤ 8%) and harzburgites (...
Article
This work proposes an improved magnetic levitation (IML) method for measuring the density of minerals in outdoor exploration by horizontally setting the magnetic levitation device. The measuring characteristic of the method is analyzed and verified by a series of beads with known densities. Combined with the usage of different paramagnetic media, t...
Article
Mantle pyroxenite xenoliths were collected from Hannuoba, East China, and investigated for their H2O content and trace element contents, with particular regard to the H2O/Ce ratio. The pyroxenites were divided into three groups: Cr-pyroxenites, Al-pyroxenites, and garnet pyroxenites. The H2O contents and H2O/Ce ratios of the pyroxenites in this stu...

Understanding the concentration and distribution of water in the Earth's mantle plays a substantial role in studying its chemical, physical and dynamic processes. After a decade of research, a comprehensive dataset of water content in upper mantle samples has been built for eastern China, which is now the only place with water content data from suc...
Article
Both mantle-derived clinopyroxene and orthopyroxene are generally homogeneous in water concentration, while water content in the coexisting olivine is affected by partial or complete loss during the ascent of the hosting magma. Here, we report the first record of water content profiles (higher water in the cores than in the rims) in natural orthopy...
Article
Metasomatism induced by melts/fluids is ubiquitous in the lithospheric mantle and can potentially modifies the initial water content of the mantle. However, the preservation of correlations between H2O content and partial melting indices (e.g., Yb content in clinopyroxene, Cr/(Cr + Al) in spinel) and the lack of correlations between H2O content and...
Article
Full-text available
The major and trace elements and H2O contents of minerals in peridotite xenoliths hosted by the Cenozoic basalts in Northeast China (NEC) were evaluated using electron microprobe, laser-ablation inductively coupled plasma-mass spectrometry and Fourier transform infrared spectroscopy, respectively. Although a potential loss of H during the xenoliths...
Article
This study presents calcium isotope data for co-existing clinopyroxenes (cpx), orthopyroxenes (opx), and olivine (ol) in mantle xenoliths to investigate Ca isotopic fractionation in the upper mantle. δ44/40Ca (δ44/40Ca (‰) = (44Ca/40Ca)SAMPLE/(44Ca/40Ca)SRM915a − 1) in opx varies from 0.95 ± 0.05‰ to 1.82 ± 0.01‰ and cpx from 0.71 ± 0.06‰ to 1.03 ±...
Article
The oxygen isotope compositions of minerals of peridotite xenoliths from the Subei basin, Eastern China were investigated to detect a possible crustal signature in mantle rocks. The δ18O values of olivine (ol), orthopyroxene (opx) and clinopyroxene (cpx) vary from 5.10 to 5.98‰, 5.46 to 6.78‰, and 5.06 to 6.31‰, respectively. Olivine and opx have δ...

The lithospheric mantle is one of the key layers controlling the stability of continents. Even a small amount of water can influence many chemical and physical properties of rocks and minerals. Consequently, it is a pivotal task to study the distribution of water in the continental lithosphere. This paper presents a brief overview of the current st...

Nominally anhydrous phases (clinopyroxene (cpx), orthopyroxene (opx), and olivine (ol)) of peridotite xe-noliths hosted by the Cenozoic basalts from Beishan (Hebei province), and Fansi (Shanxi province), Western part of the North China Craton (WNCC) have been investigated by Fourier transform infrared spectrometry (FTIR). The H 2 O contents (wt.) o...

Clinopyroxene megacrysts hosted by alkali basalts are a common form of mantle material found in Nushan volcano, Anhui Province, SE China. Compositionally, the clinopyroxene megacrysts are Al-rich augites with no intra-mineral chemical zoning. Oxygen and hydrogen isotopic ratios are constant within single clinopyroxene megacrysts, but display large...
Article
The Subei basin is located east of the Tanlu fault, a major discontinuity which separates the Archean North China Craton from the Proterozoic Yangtze Craton. South-West of the Tanlu fault the two cratonic blocks collided during Triassic time, originating the well-known UHP (Ultra-High Pressure) belt of Dabie Shan. Central-eastern China experienced...

Nominally anhydrous minerals (olivine, clinopyroxene and orthopyroxene) from 15 peridotite xenoliths hosted by Cenozoic basalts in Nushan volcano, SE China have been investigated by micro-Fourier transform infrared spectrometry (FTIR). No distinct OH absorption bands can be found in olivines, whereas all the analyzed clinopyroxene (cpx) and orthopy...
Article
When the continental crust subducted to a certain depth (∼90-110 km), almost no hydrous minerals existed in the plate, and nominally anhydrous minerals (NAMs, such as garnet, pyroxene, quartz) in ultrahigh pressure (UHP) rocks became the main carriers transporting water into the mantle. Garnet and omphacite in UHP eclogites at Shuanghe, Dabieshan h...

Nominally anhydrous minerals (clinopyroxene, orthopyroxene, plagioclase) of granulite xenoliths in Cenozoic basalts from Nushan, eastern China have been investigated by Micro-FTIR. The results indicate that water occurs in all these nominally anhydrous minerals as structural OH with the concentrations up to, expressed by H2 O wt., ∼2340 ppm for cli...
